In some instances, when there is extensive formation of immune complexes, these large molecules may be deposited in certain organs of the body and result in inflammation of local tissue resulting in immune complex disease. A shot of fresh Wheat Grass Juice. They are supposed to have a non-immunogenic phenotype and their growth in this phase lasts for around a few years — the longest phase of the three. Dear Sunil We advise her to try 1. However, vaccine ineffectiveness is most often a result in failure, whether knowingly or unknowingly, to follow the manufacture's recommendation for schedule, storage and administration.
Tetanus toxoid, for instance, is usually adsorbed onto alum. This presents the antigen in such a way as to produce a greater action than the simple aqueous tetanus toxoid. People who have an adverse reaction to adsorbed tetanus toxoid may be given the simple vaccine when the time comes for a booster. In the preparation for the Persian Gulf campaign, whole cell pertussis vaccine was used as an adjuvant for anthrax vaccine. This produces a more rapid immune response than giving only the anthrax vaccine, which is of some benefit if exposure might be imminent.
Vaccines may also contain preservatives to prevent contamination with bacteria or fungi. Until recent years, the preservative thimerosal was used in many vaccines that did not contain live virus.
As of , the only childhood vaccine in the U. Preservatives may be used at various stages of production of vaccines, and the most sophisticated methods of measurement might detect traces of them in the finished product, as they may in the environment and population as a whole.
In order to provide the best protection, children are recommended to receive vaccinations as soon as their immune systems are sufficiently developed to respond to particular vaccines, with additional "booster" shots often required to achieve "full immunity". This has led to the development of complex vaccination schedules. In the United States, the Advisory Committee on Immunization Practices , which recommends schedule additions for the Centers for Disease Control and Prevention , recommends routine vaccination of children against: In order to combat declining compliance rates, various notification systems have been instituted and a number of combination injections are now marketed e.
Besides recommendations for infant vaccinations and boosters, many specific vaccines are recommended for other ages or for repeated injections throughout life—most commonly for measles, tetanus, influenza, and pneumonia.
Pregnant women are often screened for continued resistance to rubella. The human papillomavirus vaccine is recommended in the U.
In , a vaccine was introduced against shingles , a disease caused by the chickenpox virus, which usually affects the elderly. Prior to the introduction of vaccination with material from cases of cowpox heterotypic immunisation , smallpox could be prevented by deliberate inoculation of smallpox virus, later referred to as variolation to distinguish it from smallpox vaccination. The earliest hints of the practice of inoculation for smallpox in China come during the 10th century.
They implemented a method of "nasal insufflation " administered by blowing powdered smallpox material, usually scabs, up the nostrils.
Various insufflation techniques have been recorded throughout the sixteenth and seventeenth centuries within China. In , Jenner took pus from the hand of a milkmaid with cowpox, scratched it into the arm of an 8-year-old boy, James Phipps , and six weeks later inoculated variolated the boy with smallpox, afterwards observing that he did not catch smallpox.
The second generation of vaccines was introduced in the s by Louis Pasteur who developed vaccines for chicken cholera and anthrax ,  and from the late nineteenth century vaccines were considered a matter of national prestige, and compulsory vaccination laws were passed. The twentieth century saw the introduction of several successful vaccines, including those against diphtheria , measles , mumps , and rubella.
Major achievements included the development of the polio vaccine in the s and the eradication of smallpox during the s and s. Maurice Hilleman was the most prolific of the developers of the vaccines in the twentieth century. As vaccines became more common, many people began taking them for granted. However, vaccines remain elusive for many important diseases, including herpes simplex , malaria , gonorrhea , and HIV.
One challenge in vaccine development is economic: Many of the diseases most demanding a vaccine, including HIV , malaria and tuberculosis, exist principally in poor countries.
Pharmaceutical firms and biotechnology companies have little incentive to develop vaccines for these diseases, because there is little revenue potential. Even in more affluent countries, financial returns are usually minimal and the financial and other risks are great. Most vaccine development to date has relied on "push" funding by government, universities and non-profit organizations.
The filing of patents on vaccine development processes can also be viewed as an obstacle to the development of new vaccines. Because of the weak protection offered through a patent on the final product, the protection of the innovation regarding vaccines is often made through the patent of processes used in the development of new vaccines as well as the protection of secrecy.
According to the World Health Organization, the biggest barrier to local vaccine production in less developed countries has not been patents, but the substantial financial, infrastructure, and workforce expertise requirements needed for market entry. Vaccines are complex mixtures of biological compounds, and unlike the case of drugs, there are no true generic vaccines.
The vaccine produced by a new facility must undergo complete clinical testing for safety and efficacy similar to that undergone by that produced by the original manufacturer. For most vaccines, specific processes have been patented. In the case of a few relatively new vaccines such as the human papillomavirus vaccine, the patents may impose an additional barrier. Vaccine production has several stages. First, the antigen itself is generated. Viruses are grown either on primary cells such as chicken eggs e.
Likewise, a recombinant protein derived from the viruses or bacteria can be generated in yeast, bacteria, or cell cultures. After the antigen is generated, it is isolated from the cells used to generate it. A virus may need to be inactivated, possibly with no further purification required.
Recombinant proteins need many operations involving ultrafiltration and column chromatography. Finally, the vaccine is formulated by adding adjuvant, stabilizers, and preservatives as needed.
The adjuvant enhances the immune response of the antigen, stabilizers increase the storage life, and preservatives allow the use of multidose vials. Vaccine production techniques are evolving. Cultured mammalian cells are expected to become increasingly important, compared to conventional options such as chicken eggs, due to greater productivity and low incidence of problems with contamination. Recombination technology that produces genetically detoxified vaccine is expected to grow in popularity for the production of bacterial vaccines that use toxoids.
Combination vaccines are expected to reduce the quantities of antigens they contain, and thereby decrease undesirable interactions, by using pathogen-associated molecular patterns. Beside the active vaccine itself, the following excipients and residual manufacturing compounds are present or may be present in vaccine preparations: Many vaccines need preservatives to prevent serious adverse effects such as Staphylococcus infection, which in one incident killed 12 of 21 children inoculated with a diphtheria vaccine that lacked a preservative.
Thiomersal is more effective against bacteria, has a better shelf-life, and improves vaccine stability, potency, and safety; but, in the U. The development of new delivery systems raises the hope of vaccines that are safer and more efficient to deliver and administer. Notable developments in vaccine delivery technologies have included oral vaccines. Early attempts to apply oral vaccines showed varying degrees of promise, beginning early in the 20th century, at a time when the very possibility of an effective oral antibacterial vaccine was controversial.
An oral polio vaccine turned out to be effective when vaccinations were administered by volunteer staff without formal training; the results also demonstrated increased ease and efficiency of administering the vaccines. Effective oral vaccines have many advantages; for example, there is no risk of blood contamination. Vaccines intended for oral administration need not be liquid, and as solids, they commonly are more stable and less prone to damage or to spoilage by freezing in transport and storage.
A microneedle approach, which is still in stages of development, uses "pointed projections fabricated into arrays that can create vaccine delivery pathways through the skin". An experimental needle-free  vaccine delivery system is undergoing animal testing. The use of plasmids has been validated in preclinical studies as a protective vaccine strategy for cancer and infectious diseases. However, in human studies, this approach has failed to provide clinically relevant benefit.
The overall efficacy of plasmid DNA immunization depends on increasing the plasmid's immunogenicity while also correcting for factors involved in the specific activation of immune effector cells. Vaccinations of animals are used both to prevent their contracting diseases and to prevent transmission of disease to humans. In some instances, wild populations may be vaccinated. This is sometimes accomplished with vaccine-laced food spread in a disease-prone area and has been used to attempt to control rabies in raccoons.
Where rabies occurs, rabies vaccination of dogs may be required by law. Other canine vaccines include canine distemper , canine parvovirus , infectious canine hepatitis , adenovirus-2 , leptospirosis , bordatella , canine parainfluenza virus , and Lyme disease , among others. Cases of veterinary vaccines used in humans have been documented, whether intentional or accidental, with some cases of resultant illness, most notably with brucellosis.
With the advent of aerosol vaccination in veterinary clinics for companion animals, human exposure to pathogens that are not naturally carried in humans, such as Bordetella bronchiseptica , has likely increased in recent years.
DIVA Differentiating Infected from Vaccinated Animals vaccines make it possible to differentiate between infected and vaccinated animals. DIVA vaccines carry at least one epitope less than the microorganisms circulating in the field. An accompanying diagnostic test that detects antibody against that epitope allows us to actually make that differentiation.
Monoclonal antibodies were produced against that deletion and selected to develop an ELISA that demonstrated antibodies against gE. In addition, novel genetically engineered gE-negative vaccines were constructed. The DIVA strategy has been applied in various countries and successfully eradicated pseudorabies virus.
Swine populations were intensively vaccinated and monitored by the companion diagnostic test and, subsequently, the infected pigs were removed from the population. Bovine herpesvirus 1 DIVA vaccines are also widely used in practice. Scientists have put and still, are putting much effort in applying the DIVA principle to a wide range of infectious diseases, such as, for example, classical swine fever,  avian influenza,  Actinobacillus pleuropneumonia  and Salmonella infections in pigs.
Vaccine development has several trends: Principles that govern the immune response can now be used in tailor-made vaccines against many noninfectious human diseases, such as cancers and autoimmune disorders.
Transgenic plants have been identified as promising expression systems for vaccine production. Complex plants such as tobacco, potato, tomato, and banana can have genes inserted that cause them to produce vaccines usable for humans. From Wikipedia, the free encyclopedia.

What we need to know is missing from your report. Please see your doctor about getting these additional tests, then you will be in a better position to judge if your hepatitis B is active — and causing liver damage — or inactive. If you continue to test positive for the hepatitis B surface antigen HBsAg , yes, you are still infected with hepatitis B.
Hi there, if I got my second dose May but never received my third shot, should I restart the series? I do have lab test results showing my immunity. You do no need to repeat the series.
Get your third shot of the series now and you will be good. If you have concerns regarding immunity generated, you can always choose to have an anti-HBs titre test weeks following this last shot of the series. This is not standard, but only if you have specific concerns. Will I still be protected?
Just take basic precautions while traveling — not only for HBV, but for other infectious agents. Is there a max time frame to get shot 3 from the time shot 2 was administrated? I have an employee that received shot 2 over ten years ago, can he just get shot 3 now or would it be best to start over? We have documented proof of shot 1 and shot 2. The time noted on the schedule is the minimum time in between shots in the series. Since you are sure he has had shot 1 and 2, he can go on to get shot 3 despite the length of time.
Hi, i just had my 1st shot of vaccine today before i took hepatitis B test. False-positive HBsAg results can occur during the postvaccination period. Transient antigenemia of up to 4 weeks has been reported.
Interpreting the result during this period should be made with caution. So it means the result i just had with the vaccination with the hepatitis test on that same day will be more likely negative?? If you had an HBsAg test, or hepatitis B surface antigen test then it is possible it will be positive, which could be a false positive because you were just vaccinated. If your HBsAg result it negative, then it is negative. Be sure to keep copies of your test results so you can confirm your results.
A month after the shot. The time on the schedule is the minimum amount of time in between injections in the series. Next time have the blood drawn first before getting your shot. I was really worried because i might fail my medical and my work is on the line here. Assuming you generated adequate immunity as a result of your 3 shot vaccination series, you are good.
However, if it will put your mind at ease, ask your doctor to test you for HBV. Does it mean the person can still infect even having 3 shot series? Most people who undergo the full three shots of the hepatitis B develop enough hepatitis B antibodies to protect them against infection. To be sure, you can have your surface antibodies tested one or two months after you finish the full series.
To be sure, you can be screened for antibodies. Usually, healthcare workers may try two courses of the hepatitis B vaccine series to see if a patient responds. If 1st hep b vaccination of 0,1,6 is taken on 19 nov. The shortest time between shot 1 and shot 2 is one month. You can get shot 2 after 19 December. Shot 3 is should be given 6 months after shot 1. Sir my last 3 shot dose take 5 month after 1 dose …. As long as you have had three doses over the five-month period, you should be fine.
The CDC says an accelerated vaccination dose can be used: Hi I got my heb b vaccine 1st dose in July n 2nd dose in Aug now can I take my 3rd dose in April or should I start from 1 dose Different vaccine name can take in third shot? The CDC says if you miss a dose, simply pick up where you left off. So, get your third dose as soon as possible. As long as it is a hepatitis B vaccine, it will work. You do not need the same vaccine brand for all three shots.
Good luck and congratulations on protecting your health. What are the risks of getting your 3rd shot earlier? You may not generate adequate immunity. Hi, I have shot 1 and 2 and my work is requiring my third shot done before 6 months when is schedule my last. Is something to consider? I appreciate any help. Medical guidelines recommend at least a two-month minimum between your second hepatitis B vaccine shot and your third.
If at least two months have passed, it is safe to get your third shot. If I had all 3 shots in the series years ago do I have to have them again since I am starting a job in a health related field? I am a nurse. You should be in good shape since you had your vaccine series and a booster shot, but if you did not run an anti-HBs titre, one month to two months after your last booster shot or the last shot of your 3 shot series, then you can have can one run now.
You should get your results back in a day and that will alleviate your concerns. Please try not to worry. Hello, If i am required to take the 3shot Hep B vaccination for a medical office job and only took the 1st shot, what are my risk of working with patients and blood?
I would encourage you to get the 2nd and then the third shot to complete the series. The 1 month between shot 1 and 2 may be any length greater than 1 month, so if that is your concern, you do not need to re-start the series. So do I have it or not? It sound like you may have had HBV and resolved the infection prior to being vaccinated, though you do not mention if your HBsAb is positive or negative. Your HBsAb should also be positive. This would indicate that you have immunity to HBV.
Without a previous infection and vaccine, a positive HBsAb would indicate immunity as a resolve of vaccination. If you do not know if you are HBsAb pos or neg, then you need to be sure to have this test run.
She did a hep profile chronic ,undifferentiated and it just gave the core and antigen results. I am not sure of your question. The HBV vaccine is a 3 shot series given at month 0, 1 month, and 6 months. The anti-HBs titre is run to determine if you have generated adequate immunity as a result of the vaccine series. Sept I was again able to get a booster shot from the healh company I work in. I sometimes had small wounds on my hands but cant keep that latex gloves worn the whole time.
You are most likely good, but I think the best way to alleviate your concerns about your HBV immunity is to have your anti-HBs titres checked.
Thanks for the response. I got another question though, i had my titre test done a month after the last dose. How possible is that where in fact i already got a series of shots and recently had my boosters last sept 13 followed by nov 22 and had my titre done on december 25? You need to talk to your boyfriend about your HBV.
He needs to be tested and if he is not infected, then he needs to complete the vaccine series. Please be sure you are being monitored by a liver specialist about your HBV. Am i protected somehow? And does it have a situation like you have a sex contact with chronic hepa b for several time but you have a good immune system, can you get the infection easily? Hepatits B is transmitted through direct contact with HBV infected blood and body fluids, which means it is also a sexually transmitted disease.
If you have not completed the vaccine series and you believe you have been exposed, then you need to be tested. Look through these blogs and our website www. Have some information available for him to refer to about HBV so he can learn.
Is there a risk in taking more than 3doses? There is no risk in getting the vaccine repeated if you need the vaccine for your records. However, check to see if they are willing to take the titre as a substitute for the repeated vaccine series. The vaccine is safe to have even if you are vaccinated while you are pregnant.
Have you been tested to be sure that your husband did not transmit HBV to you prior to vaccination? Please check with your doctor. I am about to start taking classes for a health field, and we are required to have HB vaccinations.
If I got it when I was an infant, do I have to get a whole new round, a booster, or am I still protected? Everyone is a little different, but most likely you are protected. However, you will need to have your anti-HBs titres checked so you can confirm you have adequate immunity.
If not, then you should get a booster shot. One month following the booster shot, you will want to repeat the anti-HBs titre test. That being said, you will want to see what your school is going to require — proof of vaccination, or proof of immunity. If your job will put you at risk then I would encourage you to have the anti-HBs titre test to confirm immunity.
Hello, I am getting ready to start medical school in a few months. I did a titer count and found out that I have no immunity for Hep B.
It looks like I had my first shot in However, when I asked the school nurse at my college, she said I had to restart from the first shot since the first one was back in The Health Department nurse is correct. You do not need to restart the series. The time in between shots in the series is the minimum amount of time necessary to generate adequate immunity. How safe is to have sex Unprotected after 2 doses? If it is not safe now, when exactly she would be completely protected?
What treatment is recommended Oral Medicine or Interferon? We consulted couple of doctors and we got different opinions. I would encourage that you practice safe sex until she has completed the series. She can also have an anti-HBs titre run 1 month after the last shot of the series to ensure she is adequately protected. Be sure to avoid sharing personal hygiene items that may have traces of infected blood on them such as razors, toothbrushes or nail clippers.
Was your wife screened for HBV to be sure she was never infected? Talk to your doctor about whether treatment is a good option at this time. You may want to be closely evaluated and monitored to see if there is a change in your viral load, ALT going up and down, family history, HBe positive or negative HBV?
I received my first shot in November, second shot in December and the last in June. The time in between shots in the series is the minimum amount of time. However, the fact that you were off by a couple of days is hard to know for sure if you will be able to generate adequate immunity. An extra shot will not hurt you, so if you believe the shortened time in between shots 1 and 2 will be an issue, then you can repeat it.
One month after the 3rd shot in the series you can have an anti-HBs titre test run to see if you have generated adequate immunity. Once again you can confirm immunity with a follow up titre test one month later. Thanks for your help and this website. It sounds like you have completed the series and you are concerned that you may not have generated adequate immunity?
That should do it, but if you do not generate adequate immunity you can literally repeat the series one shot at a time followed by titre testing one month later.
There are also accelerated schedules. You can do 0, 1 month, 4 months, or you can even try: I had hep b when i was little do i need to get the shots or does it matter.
If you have or have had HBV then you do not need to be vaccinated. The vaccine does nothing for those already infected or previously infected. Are you sure you resolved your childhood infection?
My husband is hep positive, I had receive all 3 doses of hep b vaccine before I met my husband, I tested negative after he was diagnosed.. I have immunity when my doctor checked my titter levels last year. Does it matter if I recently this year got an extra dose of the hep b vaccine by mistake?
It was a medical error and am worried I will now be less immune. Will that hurt my already immunue system to hep b? I guess my worry is due to the random one dose would I become less immune?
Also, being that I a at continue exposure to hep b from my husband positive status, do I at any point need a booster shot, how often should I check my immunity level. Am I immune for life…. Your extra shot would be considered a booster shot and it will not hurt you. If you want to ensure that your immunity generated is adequate, you can ask your doctor to run an anti-HBs titre test months following your booster shot.
If you do not generate immunity following your booster shot, you can continue with the series and test anti-HBs titre 1 month after the last shot of the series. Do they test for Hep B before giving Hep B series vaccine? I want to confirm that if a person has completed the series vaccination they are negative for Hep B.
It is not standard to test someone for HBV prior to vaccination. However, you can always have a hepatitis B panel run before vaccination to confirm the person does not have HBV. If you are concerned that someone that is already vaccinated has HBV then you can still run the hepatitis B panel to see if they have a current or previous infection, or if they have immunity from the vaccine or from a previous infection HBsAg, HBcAb, HBsAb.
Hopefully your child was vaccinated within 12 hours of birth and was also able to receive a shot of HBIG at the same time, since you are a HBV carrier.
Extending the time in between shots in the HBV vaccine series is okay. Shortening them is not okay. Please be sure your child is tested for HBV at 18 months. It is recommended that any child born to a hepatitis B-infected mother get the first vaccine shot within 24 hours of birth to prevent infection. If this could not happen, please get your child immunized as soon as possible, and also see if the baby can be given a dose of HBIG hepatitis B antibodies to also prevent infection. Make sure your baby gets the second hepatitis B vaccine shot 30 days after the first dose, and the third shot five months after the second dose.
Im so scared now… Please help…. Did you talk to your doctor? Prophylaxis is available, but it is really only effective in the first 48 hours. Since you are beyond that, you should get a hepatitis B panel weeks after having sex with your girlfriend since there is a window before you would actually test positive, if you were infected.
Please be sure to have protected sex until you have been tested and until you have your 3rd shot of the series. Take basic precautions to avoid transmission to others. I recived my Hep B shots in November is there a chance that I would come up with positive test results after getting the shots?
I was not positive before I got my shots. If you were tested within a month of one of the shots of the series, it is possible you will generate a false positive. You cannot get hepatitis B from the vaccine, but if you happened to be infected prior to receiving the vaccine, it will not help and you would test positive. Please retest to clarify. Unfortunately your child received the final shot of the series too soon. The time in between shots is the minimum amount of time.
I am reading these posts hoping and praying that these folks have been properly informed that just because youve had these shots doesnt mean you cannot get it.
I took the shots myself. Idrove a school bus for handicap children it was required of me. I Couldnt believe me ears when this doctor told me this. Im still being treated with viread this medaacine makes me so evil.
Moody you name it. I was remarried you see Sept. I never ever used a needle. The only way i could have caught it was unprotected sex or by one of the 2 blood transfusions i had in or ,. I will tell you i sit here sick today i took the HBV vaccinations.
I am very sorry to hear of your chronic HBV infection. The HBV vaccine is very effective, but there is a certain percentage of the population that are non-responders to the vaccine. This happens with all vaccines.
The other possibility is that you were infected before you received the HBV vaccine series. The vaccine is not effective for those already infected. It may be impossible for you to determine the source of your infection. Please know that there is no shame in having this virus.
However, having a chronic illness, and one that often has a stigma associated with it can be difficult to cope with. I had my antiHBs titers since its required in my univ.. Your anti-HBs titres look good. You do not need a booster shot, nor do you need to repeat the series.
The titre should be adequate to show proof of immunity at your school. I would encourage you to get the 3rd shot of the series. You might also want to consider getting tested prior to vaccination. I was wondering, I got my first shot in Oct 25, and they rescheduled me to come in for my 3rd shot in February 25, I just got the shot, but now I was just informed that I was supposed to get my 3rd shot 6 months after my first shot… Are there any effects if I got the shot too early?
About 2 months early? There is no danger in getting the vaccine early. You can determine this by getting an anti-HBs titre test months following the last shot of the series. The additional shot will not hurt you. I got the three shot series, checked my titer and it was less then 0. What do I do? Please read the following blog: Options for vaccine non-responders http: These are good options for people who have difficulty generating an immune response to the HBV vaccine. You may want to print this out and bring it to your doctor.
You need to complete the series by getting the third and final shot. It does not matter that it has been a long time. If you believe you were exposed to HBV, please know that you were not fully protected with the 2 shots of the vaccine series. Consider being screened for HBV prior to the 3rd and final shot. You have been very fortunate to not get infected. It is possible that your partner is currently in the inactive phase and not as infectious.
However, that can change, and you would not be aware of it. We are so fortunate to have a vaccine available to protect against hepatitis B. I plan on starting a Phlebotomy program just as soon as i finish my hepatitis B vaccine series. Yesterday, I received my first shot in my left arm, and also another shot for taking hepatitis A in my right arm. Today I spoke with the recruiter for school and she informed me that that taking those 2 vaccines together cancel each other out, and that I would now have to wait an entire year to start class because i would need a booster shot.
I informed her that the shot was not the twinrec but two seperate, adult vaccines… Has anyone ever heard of this? Also, is it possible to take the 3rd shot in 5 months instead of 6? The travelers accelerated schedule for HBV is 0, 7 days and days and then a booster shot at month Since you will dealing with blood, you would want to have an anti-HBs titre to be sure you have generated adequate immunity. Should you decide to do the 3rd shot at 5 months, definitely get your titres checked months following the last shot to be sure you generated adequate immunity.
I would think if you show you have generated adequate immunity, that would be enough to ensure you are good from the program. The vaccine can sometimes result in a false-positive if tested within a month of the vaccine. Additional testing and reading of the results by a liver specialist will clear this up for her. Please encourage her to look into this situation more closely.
However, some schools and jobs may require a titre test to confirm adequate immunity before being accepted into a program or position. This would be for people who had already completed the 3-shot series. If they find their titre has waned, they would need a booster followed by a titre test a months after the booster to confirm immunity and permit them into the program.
Would you be capable to information me personally in your webmaster or the dude which looks after your blog post, I must know if it could be simple to be a visitor poster. If you would like to post about your HBV experience, you can send an email to info hepb. I had titers drawn which showed no immunity. I just completed my third vaccine today for the series. I am scheduled to get new titers drawn in four weeks. The nurse informed me that if i am still not immune, i probably have hepatitis b and need an antigen level checked.
Is this true because i am freaking out. Wait to see how your anti-HBs titre test comes back in a month. Please know that there is a percentage of the population that are vaccine non-responders. This is true for all vaccines. My friend had donated blood last December and the bloodbank told him that he was Hepa B core antibody positive but Hepa B surface antigen negative. He only know that he had the symptoms of having hepa 12 years ago. His wife had a 2 vaccine dose prior to their marriage and he doesnt know if he will transmit it to his wife.
He has also a 3 years old daughter to another woman, will it be possible that the child may have it. It sounds as though your friend had a previous HBV infection which he has resolved. He is not infectious since he has resolved the infection, but since his wife has had two out the three shots of the HBV vaccine series, she may as well complete the series so she can be protected in case of future exposure. It does not matter if the time between shot 1 and 3 is well beyond 6 months. I think it would be a good idea to see if the mother of his child and his daughter were infected.
Unless he can confirm an infection, and clearing of the infection 12 years ago, it would be best to just be sure neither of them are infected. He has not yet been positive to HbsAb because it have not been tested with him. Now his wife has 3 doses of vaccine and is positive to HbsAb already.
Are the wife safe now because they want to have a baby. Do you know if you generated adequate immunity after your vaccination? This would have entailed having your anti-HBs titre checked months following the last shot of the vaccine series.
You can have those titres checked at this time, but it is possible they have waned and not enough is circulating. The booster shot of the vaccine will not hurt you, but there is a good chance, but no way to prove if you have adequate protection. I got all Hep B shot , doctor office gave me one month one shot so I completed all 3 in 3 months. A week later they told me to get blood work done. I did, the result show I still negative. Doctor sent me to get another blood work it about 3 weeks after I got the first blood work done.
In fact I should have it on month six. In this case I would like to know is anything about this mistake from this treatment HepB third shot wrong time will cause me any health issue?
Getting the 3rd shot of vaccine series will not hurt you or cause a health issue. However, you did not generate adequate immunity as a result of the vaccination since you did not get the 3rd shot of the series at 6 months.
Please be sure it has been 6 months since shot 1 of the series and get a booster shot. A month after the booster shot, ask your doctor to run an anti-HBs titre test so you can see if you generated adequate immunity. Most likely you will and you will be protected. Hello, I got the third shot in May at 20 months of age and was exposed to Hep b one month ago. Should i check for HBV?
Does the immunity last for such long time in patients vaccinated early in childhood? Assuming that you generated adequate immunity following the 3-shot series completed at 20 months of age, you will be fine. If you are concerned, ask your doctor to run a hepatitis B panel, just to be sure. Remember there is a week window after exposure when you would not test positive even if you had been infected.
It is not at all uncommon to do a titre test 1 month following the last shot of the vaccine series for those working in health care. Most likely you will be fine, though there is a small percentage of the population that are vaccine non-responders which means they failed to generate adequate immunity following 2 complete series of the HBV vaccine.
I have had my shot 1 and 2, but my parents did not give me the 3rd it has been 20 year since these 2 shots, can I just get my 3rd shot and be good after this time? And will the titer show if I am good? The time in between shots in the series is the minimum amount of time between shots in the series. Get your 3rd and final shot and then get an anti-HBs titre run months following the series if you want to confirm you immunity.
I have a question, i am 24 male I have completed my hep b regimen when i was little, with booster shots growing up I took up nursing as my premed course and we are required to have hep b vaccine before our exposure in the community and hospital. I was 19 that time.. I have only recieved 2dose of hep b vaccine and did not have the chance to take the 3rd dose. But im sure i have no exposure before getting the vaccine..
I am now 24yrs old.. I had exposures like needle pricks, assisting a delivery with a hep b mom, and a few sex oral sex done to me, never for vaginal or anal sex , im perfectly fine. Does it possible that i am have been infected for hep b?? I never had a hepatitis before neither their signs and symptoms of it? Its possible that i am a chronic carrier now??
It sounds like you were vaccinated to protect against HBV — perhaps more than once, and now you will be required to take an anti-HBs titre test? Were you vaccinated later in childhood where you could have been exposed prior to vaccination? Did you actually complete the entire series?
If you know you have completed the HBV vaccine series and close family members do not suffer from chronic HBV, then I would try not to worry about it. Get the titre test and most likely it will be fine. If you do not show adequate titres, then get a booster and repeat the titre months later. If you still do not generate adequate immunity then you should ask your doctor to run a hepatitis B panel.
HBV is typically a silent disease and often has few or no symptoms. Its been 4 yrs since i got another hep b vaccine and i dont know if my vaccines are enough to protect me with the infection full dose regimen in infant and 2dose only not completed 3rd dose and after 4yrs a hep b vaccine. I can only encourage you to have your anti-HBs titres tested, or if you believe you may have been exposed to HBV, then have a hepatitis B panel run to confirm one way or the other.
If you received HBV vaccination at birth and you were not born to an HBV infected mom, then you are most likely fine and protected by the vaccine. There is a small percentage of the population that are non-responders to the vaccine, which it is why it is important to have your titres checked to confirm immunity if you are considering working in medicine. I completed the 3 shots of hepa b but I lost my records.
Get an anti-HBs titre test run. I have done my shots on an accelerated schedule. Do you think there will be a problem doing the 3rd shot 10 days early? Or staying on schedule and doing the titre 24 days after the 3rd shot? I have to have all this done in order to apply to RN program and nothing can be pending. What are my chances that the result will show quantative immunity? The amount of time between injections is the minimum amount of time which should enable the person to generate adequate HBV immunity.
There is a small percentage of the population that are non-responders in general, but most likely you will not fall into that category. You can always repeat the titre. You might well generate a titre if you get the shot early, but you do want to be sure you generate longterm immunity.
On the much accelerated travel schedule, the person gets a 4th additional shot at 12 months. Hi, I need to show a paper in a months that I have been vaccinated, but I just found out that I have only got 2 shots.. It was done approximately 5year ago. I am going to the clinic to sort this out but I also wanted to ask here.
Is it possible to get the booster shot now? If possible, what is the possibility of getting enough titer after it? The time in between shots is the minimum amount of time between injections. Get your 3rd and last booster shot now and have your titres tested months afterward to confirm you have generated adequate immunity.
Hello again, I found out that I had completed the 3shots 16years ago and had a booster in Then I got 2shots 5year ago…. Honestly you should be fine since you have nearly completed 2 series of the vaccine, but if you have not had your titres tested, you will want to do that to be sure you generated adequate immunity.
Thank you for your responces. I will receive the results in a week or 2. I hope I have enough titer. How is the effectivity of hepaB vaccine? It is an effective vaccine, though it sounds as though you did not complete all 3 shots of the series. I am not sure based on your comment. It sounds like you may have only had 2 out of the 3? If that is the case, then you may not be adequately protected.
Please be sure to have your doctor run a hepatitis B panel so you can determine whether or not you have HBV. This is very important. If you find you do not have HBV, please be sure to complete the vaccination series so you can be sure you are protected. If you are working in health care, I would recommend that you get an anti-HBs titre drawn months following the last shot of the series.
Is there any significant findings about this timing? And why CDC choose to recommend vaccination as early at this age around 12 hrs afterbirth? Because babies and young children are most susceptible to hepatitis B. I am not sure about the 12 hours.
I would like to ask if two live vaccines were given less than 4 weeks, say first dose was mmr followed by chicken pox. Which is the failure vaccine? How will you give now their booster doses?
It is not at all uncommon for multiple vaccines to be given at the same time. I was vaccinated for hepatit b in ,vacine was not respondet so I get anouther cours of vacination. I went to check if I got immunity for the vacine and after that they sad to me that they need to make anouther blood test becouse is posible to hepatit b positive.!!! I believe I addressed this. Sorry for any redundancy. If a person does not generate immunity after 2 complete vaccine series, then they are considered a non responder and would be tested to be sure they do not actually have HBV and that is why they are unable to generate immunity.
This is standard procedure, so please do not panic. If you find you do not have HBV, you can look at some of the recommendations from the blog: I had my 1st shot and then my 2nd shot but its been 7 months for the 3rd shot does that pose a problem? I am in the nursing program and it is required but I was suppose to get the 3rd shot 6months from the 2nd.
I am concerned that I will have to start the series of shots over and if thats the case I want to start now before September and the school tells me I can not start. The time in between injections is the minimum amount of time according to schedule.
Please get your 3rd shot to finish up the series. It will not be a problem. If you are vaccinated on the accelerated schedule, please be sure you have your anti-HBs titres checked one month following 3rd and last injection to confirm immunity.
Many nursing schools require this titre check so keep your lab records. They will not respond like those who do not have HBV. You already have large amounts of HBsAg circulating in your blood and your body is not able to generate an immune response.
Getting a vaccine will not help that response. That does not make any sense. Perhaps he is having an HBV injection and also getting other injections at the same time? The vaccine is administered at 0, 1 month and 6 months. This is the minimum amount of time in between injections in the series. He will not generate immunity to HBV if he receives all 3 injections at the same time! Hello, I have had the Hep B vaccine 6 times in the past 10 years due to not keeping good records.
Is this harmful to me in any way? No, it is not harmful to repeat the series, but there is certainly no reason to repeat at that level. Get an anti-HBs titre and see if you have adequate titres. Hi hepbtalk, can you help me with my case.. I was vaccinated as infant, full 3 doses, and i received boosters till Lately i pricked myself with a lancet needle of a patient of unknown status… I work in a pharmacy where we do regular glucose monitoring tests..
I have never done anti-HBs titers, but again i had my fair share of boosters… What are my risks of getting infected… Thank you. Your risks are low, but for peace of mind, I would consider having your titres run. So consider getting a booster and have the titres checked months after the booster. Hepatitis B Series completed, titre negative. Received 2 booster shots — and repeat titre negative.
Should full hep B Vaccine series be received again? How many times can you receive the full Hep B Vaccine series — if you continue to not develop the level of immunity needed for protection? A person is not considered an HBV vaccine non-responder until he has gone through 2 complete vaccine series. It will not hurt you if you get more than one series of the vaccine.
You may benefit from vaccination with a higher concentration of the vaccine. I took 3 shot of HB vaccine early , though the the 3 shot was given a month interval for each. I have been given the next appointment. Though I work in the hospital as hospital attendant. It is natural for hepatitis B surface antibodies anti-HBs , which indicate we are immune and protected from infection, to decline over time.
When people have an accelerated vaccine schedule, as you did, one of the recommendations is to go and get one more shot a booster at one year. You can wait a month and get tested again for antibodies, or just undergo the full three-dose series again. It will not harm you. Thank you for your response and one final question. The other scenario that can occur is when someone is vaccinated to protect against HBV, but they may already have an infection.
When this occurs the vaccine is not effective and the person may assume they are protected when they are not. There is a week window where you would not test positive even if you had been infected due to your exposure. That means I cannot tell you if you have hepatitis B as a result of your exposures as a result of unprotected sex. I would encourage you to practice safe sex until you clear the week window. Then you should be re-tested.
If you do not have HBV, then be sure to continue with the 3-shot series to protect you from getting HBV from your gf, or others means of transmission. Okay, so it looks like you completed the 3-shot HBV vaccine series, which is good.
The only way you will know for sure whether or not you contracted HBV before you received the vaccine is to get tested. Ask your doctor to run a hepatitis B panel. You might also consider getting a titre test should be done months following the 3rd shot of the series to ensure that you generated adequate immunity as a result of your vaccine.
Hi, I got my Hep B vaccine 3 doses when I was younger. I am going to med school this year and I went to get blood work to prove I was immune. So now, I am getting the whole series done again. How does this happen and why? It's sort of stressful too because I need the vaccines in order to start med school. The problem is there is no way to confirm you generated immunity when you were first vaccinated.
That should do it, but if not, then you can complete the series and then do the titre a month after the last shot of the series. The time between shots in the series is the minimum amount of time between injections. You may not generate adequate immunity if you do not wait an adequate amount of time!
You can consider the accelerated schedule for travel which is a 4 shot series, which is given at 0, 7 days, 21 days and month The booster shot at 12 months provides long-term protection. If you will be performing any at-risk activities, you may wish to consider an anti-HBs titre months following the last shot of your series to be sure you generated adequate immunity.
I got it though last July 19, Does the vaccine still have an effect on me? When should i get my third shot considering that my second shot was moved? The time noted on the vaccine schedule is the minimum amount of time in between shots. Get your 3rd shot of the series 6 months after the first shot of the series. The goal it to be fully protected a soon as possible, but if you are a little late in between shots, then it will not affect generating immunity. But when i took him to his reg ped, his ped said the shot 3 was injected too early so he said to do it again.
The shot 3 was injected when he was 5 months, not even 6 months old yet. So do u think he has to repeat the 3 shot again? You can either do a blood test to check the anti-HsAb titre of your child and if it is adequate skip the 3rd shot, or you can just repeat the 3rd shot. I got my hepa b vaccine last april and i didnt took the 2nd and 3rd shot since now.
What should i do? Should i took 2nd and 3rd shot or repeat the whole thing? Sounds like you have had only the first shot. You do not need to repeat the first shot, but continue with the 2nd shot, and then the 3rd. If you want to confirm your immunity to ensure you are protected against HBV, then you can have your anti-HBs titres checked months following the 3rd shot of the series. I work in a hosp setting i got my vaccine 6 yrs ago i have checked my titer 5 mos ago and it was Am i totally safe if i will b exposed to hep b?
Your anti-HBs titres are fine. You did not need to repeat the vaccination series. There is no reason for you to complete the 2nd series, though it will not harm you. An anti-HBs titre of From the first February 2 and third shot it will be in 7 months. Is it to late or not? The time on the schedule in between shots in the series is the minimum amount of time, so if you need to extend the time, that is fine.
How is that possible? Sometimes the titres will wane over time. Get a booster shot of the HBV vaccine and have your titres checked months later. I get my 1st booster and wait a month for my 2nd booster. Is this the first time you are being vaccinated or are you getting a booster shot?
The HBV vaccine series is a 3 shot series, so you need to complete all shots in the series to confer longtime immunity. If you wish to confirm immunity you can have your anti-HBs titres checked months following the last shot of the HBV vaccine series.
I got my first hep b vaccine last february twinrix and completely forgot to return for the rest. I got my 2nd dose of twinrix in may. Do i have to start the whole thing all over again, or can I just get the hep b vaccine and still be immunized??
The time in between injections of the series is the minimum amount of time, so you do NOT need to restart the series. You want to wait at least 5 months between shot 2 and shot 3 for twinrix so get it in October. It is safe for you to get the third and final shot of the series while you are pregnant, but if you decide to wait, that is okay too. So yes, you can wait until after the baby is born if you would prefer. Please help me My hisband and i would like to have a baby. I have just finished my 3 shots.
Is it already safe to concieve? And when would be the best time is it weeks or months or could it be Days after i jave completed my vaccine to try to have a baby. Glad to hear you completed all 3 shots of the series. Wait one month from the time of your shot of the vaccine series and ask your doctor to run an anti-HBs titre test. This is a test that returns a number. Just be sure to have baby receive the first shot of the HBV vaccine series before he or she leaves the hospital and follow up according to schedule for the other 2 shots in the series.
I have been tested postive for hbv, the doctorl told me that I recovered I was Immune. I took the first two shots, my anti-hbs is currently 10 and negative for hbsag I just want to know If I am immune and completely recovered! You are recovered and immune, but in the future be sure to remind your doctor or future specialists of your resolved HBV infection.
This is particularly important in the event that you require longterm use with immune suppressing medications. The doctor told me the vaccine is stil appropriate because the viral replication takes 40 days.
I cannot sleep at night thinking I might have hep b. Is anything else I can do? HBV is transmitted through direct contact with infected blood — literally blood to blood his blood to open abrasions on your hand. It was good that you were vaccinated after the exposure to a patient with hep B.
Please complete the vaccine series to protect against future exposures. Be sure you are screened for hepatitis B weeks after the exposure to be sure you were not infected. While you wait take care with sexual partners by practicing safe sex and do not share personal items such as razors, toothbrushes, nail clippers, body jewelry or items that may have very small amounts of blood on them.
Hopefully you will learn you were not infected and you will complete the series and be protected. How much time to take my HBsAg become negative. Dr told that it was acute. My partner take 2 dose of vaccines.
Can acute hep b come again if it is previously cured?? Can i take hep b vacine after recovering from acute hep B. After recovering from this also is their any chance to spread heb b to my partner? It may take as long as 6 months though certainly may be less to clear an acute hepatitis B infection. Once the infection is resolved and they develop immunity, they cannot get HBV again and they will no longer transmit the virus to others.
Most employment screening tests screen only for HBsAg, so once you have cleared the virus, you are good. There is no reason to get the hepatitis B vaccine. Be sure to confirm that you have resolved your HBV infection. In the future, you need only tell the doctor about your resolved acute infection if you are in need of long term immunosuppressive drugs in the future for conditions such as rheumatoid arthritis, psoriasis, cancer etc. Otherwise, you are good.
I am a Registered Nurse and completed my course of hep b vaccinations in This indicated I was immuned which is a requirement to work for the health service i am in. How is it possible to be immuned then 2 years later not be? It is a scary prospect to think there are others out there that think they are immuned but are not. I would have never known if I didn't get pregnant. How common is this? Since you had your titres checked following the last shot of your vaccine series you are protected.
The titre level may drop below the acceptable range with time. Immune memory would protect you in the event of an HBV exposure where you would once again generate surface antibody.
The levels may not be high enough to trigger the test, but your immune system will launch an attack if exposed. Often people do not check their immunity months following the HBV vaccine series, so they never no if they ever generated immunity. That being the case, since immunity was not confirmed, a booster shot would be recommended since there would be no way to confirm one way or another if they had ever generated immunity.
On going studies show those that have generated immunity will be protected 25 years, or the length of these ongoing studies. I took my second hep b shot only 3 weeks after the first shot due to some confusion with my general physician and OBGYN, and my forgetfulness.
