Hepatitis B Vaccination In Pregnancy
Hepatitis B infection in pregnant women may result in severe disease for the mother and chronic infection for the baby.
This is why the hepatitis B vaccine is recommended for pregnant women who are in a high-risk category.
There’s no evidence of any risk from vaccinating pregnant or breastfeeding women against hepatitis B.
And, as it’s an inactivated vaccine, the risk to the unborn baby is likely to be negligible .
How Long Does Hep B Vaccine Last And Who Should Take It
Hepatitis B vaccine is one of the most common vaccines today. It is used to develop immunity to Hepatitis B, a heavily contagious disease caused by the virus of the same name.
According to the Centers for Disease Control and Prevention, Hepatitis B is in decline in recent years. The figures have dropped from around 200,000 new infections a year in the 1980s to an average of 20,000 in 2016.
Contracting the virus doesnt necessarily put you at risk of a chronic infection. For individuals above the age of five, the chances of that happening are between 5 and 10%. Younger children are at a much higher risk. Under the age of five, the estimation is 25-50%. Infants run a 90% chance of developing a chronic infection if they contract the Hepatitis B virus.
The Hep B vaccine is the most common prevention methods for Hepatitis B, with the first vaccine being approved in the United States in 1981. In 1986, the first recombinant version became available. But how long does Hep B vaccine last? This article will explore the question. The possible side effects, risk factors and risk groups will also be considered.

The hepatitis A & B virus is silent but violent. The virus is 50 to 100 times more contagious than HIV and can survive outside the body for at least seven days, making it much more infectious then most infectious diseases.
Nobody is immune to the first infection, and once contracted, it can lead to chronic illness and, in extreme cases, even death.

Two versions of hepatitis B vaccine are available. One, called Heplisav-B, contains a novel adjuvant that was not present in previous versions used by adults . Some people did not respond to the older version hepatitis B vaccine. In fact, in a group of adults younger than 40 years of age who received two doses of the older version vaccine 75 of 100 were protected. Following the third dose, this number increased to 90 of 100. However, people older than 40 years of age were less likely to respond to the vaccine with increasing age. On the other hand, 90 to 100 of 100 adults 18 years of age and older respond to Heplisav-B, which was approved for use in 2018.
About 5-10 of every 100 children and adults younger than 40 years of age do not respond to the third dose of the hepatitis B vaccine. Some of these people will be recommended to get vaccinated again. About 5 of 100 people will still not respond after getting all recommended doses of both series. Note that children younger than 18 years of age cannot get Heplisav-B.
If the people who do not respond to vaccination are determined not to have chronic hepatitis B, they will be reliant on taking precautions to reduce the chance of exposure and relying on those around them for protection. In other words, these people will be reliant on herd immunity.
How And When Do Doctors Give Vaccines
For the hepatitis A vaccine:
You should get two doses, given as shots, 6 months apart for complete protection. The virus in the vaccine is killed .
Children should get the first dose between 12 and 23 months of age. Children older than age 2 can get the first dose at their next doctorÃ¢s visit.
If you need the vaccine because of upcoming travel, get it at least 1 month before you go.
For the hepatitis B vaccine:
For long-lasting immunity, you need three to four doses, depending on which type of vaccine is used. You get them as shots.
Children should get their first dose at birth and complete the series by age 6 months. Usually, the baby would get a second dose at 1 month old and the third dose at 6 months.
Babies born to women who have hepatitis B need a shot of hep B antibodies, as well as their first hep B vaccine shot, when theyÃ¢re born. They will also need follow-up blood tests to make sure theyÃ¢re OK.
Catch-up vaccinations are recommended for children and teens who were never vaccinated or who did not get all three shots.
If youâre an adult who wants to be vaccinated, you should talk about it with your doctor or pharmacist. If you are considering both vaccines, ask your doctor about vaccines that combine hep A and B.

Other Important Hepatitis A Vaccine Facts
People who are on hemodialysis and those with AIDS shouldnt worry its safe for them to get vaccinated since its an inactivated vaccine. Whats more, there is no harm in receiving additional shots if a person lost his medical history.
In some cases, prevaccination testing may apply. This is usually done to keep the vaccination cost down and may include people of certain ethnic groups and those who live in areas with high hep A incidence rate. The same rule applies to intravenous drug users.
The protection usually begins two to four weeks after the first shot. In light of the long incubation period of the hepatitis A virus, the protection may start right away.
Hep A isnt treated with any antivirals and the liver has a remarkable ability to self-regenerate. Doctors usually prescribe sufficient hydration, plenty of rest, and proper nutrition, though some people might need to be hospitalized for additional medical care.
Who Should Get The Vaccine
The Hepatitis B vaccine is recommended for all infants and children aged between 0 and 18. In the case of infants, it is recommended to take the vaccine at birth, while still in hospital. In cases where the vaccine was omitted at birth, its important to complete the 3-shot series as soon as possible. Adolescents and adults who havent received the vaccine on time are also recommended to complete the vaccination as soon as they can.
Members of the following at-risk groups should take special care to get vaccinated: healthcare workers, people in treatment for another STD, the partners and household members of individuals with HIV/AIDS, prison inmates, intravenous drug users , sexually active people who are not in exclusive relationships, men who engage in sex with other men, residents and staff of homes and facilities that care for the developmentally challenged, and people with serious kidney diseases .
Some US populations have a substantially higher rate of HBV infections. This includes Pacific Islanders, Alaska Natives, as well as immigrants and refugees from endangered territories and countries. People who belong to these endangered groups are highly advised to take the vaccine.

Hepatitis Vaccine: What You Need To Know
Hepatitis is an inflammatory liver condition. There are five types of viral hepatitis: A, B, C,D, and E. Most cases are caused by a hepatitis virus. The condition can also be a result of excessive alcohol or drug use or a faulty inflammatory immune response that occurs when the immune system mistakes the liver as a threat to the body and begins to attack it.
There are two hepatitis vaccines that can help prevent hepatitis A and B infections. A third vaccine, developed for hepatitis E, is only permitted for use in China. This article discusses the types of hepatitis that can be prevented with a vaccine and what you need to know before getting one.

For How Long Is The Hepatitis B Vaccine Effective
The duration of immunity to hepatitis B virus from plasma-derived vaccine was generally believed to be around 10 years. However, rigorous determination of the upper time limit for immunity has not been carried out. Such information could be useful in devising vaccination schedules and possibly for developing public health policy with respect to the rationale for and timing of booster vaccinations.
McMahon and colleagues at the Centers for Disease Control and Prevention studied 1578 Alaska Natives vaccinated at age 6 months or older between 1981 and 1982. Subjects received three doses of plasma-derived hepatitis B vaccine appropriate for their age, and were tested annually for antibodies to hepatitis B surface antigen and HBV infection markers for the first 11 years.
Anti-HBs levels decreased in the study population from a mean concentration of 822 mIU/mL after vaccination to 27 mIU/mL at 15 years. Higher levels of anti-HBs were noted in males, individuals with higher initial anti-HB levels, and those who were older at the time of vaccination. After adjusting for initial anti-HBs level and sex, the lowest HBs levels at 15 years post-vaccination were observed in those vaccinated between 6 months and 4 years of age.
Researchers detected asymptomatic breakthrough infections in 16 participants. Infection occurred more frequently in vaccine non-responders than in responders .

- have household or sexual contact with / are frequently exposed to an infected individual
- come from, or are living in, a community where the rate of hepatitis A or B is high
Concurrent Administration Of Vaccines
HA vaccine may be administered concomitantly with other vaccines or with Ig. Different injection sites and separate needles and syringes must be used for concurrent parenteral injections.
If concurrently providing HA-containing vaccine and Ig, separate anatomic injection sites should be used for each injection.
Passive immunization with human Ig preparations can interfere with the immune response to measles-mumps-rubella , measles-mumps-rubella-varicella and univalent varicella vaccines . These vaccines should be given at least 14 days prior to administration of a human Ig preparation, or delayed until the antibodies in the Ig preparation have degraded. Refer to Blood Products, Human Immunoglobulin and Timing of Immunization in Part 1 for additional information.
Refer to Timing of Vaccine Administration in Part 1 for additional information about concurrent administration of vaccines.

Hepatitis A And B Vaccination
Effective and well-tolerated hepatitis A and B vaccines are available either as monovalent formulations or in various combinations. Although the benefits of a full primary vaccination course are clearprotection against potentially life-threatening diseasesthe requirement for a booster varies in different countries. Recommendations for the administration of hepatitis boosters in the United States, the United Kingdom, and Germany illustrate this. In the United States, a hepatitis B booster is not recommended for children and adults with a normal immune status , whereas in the United Kingdom, administration of a single booster dose 5 years after completion of the primary course is deemed necessary . In Germany, for example, Empfehlungen der Ständigen Impfkommission recommendations published in July 2004 state that immune response should be checked for persons who are immunodeficient and suggest the same for persons aged > 40 years. For persons with antihepatitis B surface antigen titers of < 100 mIU/mL, 1 extra dose is recommended, followed by an additional antibody test. In vaccinees with anti-HBs titers of > 100 mIU/mL, a booster is recommended after 10 years when the potential for risk continues . The World Health Organization has recognized that almost all children are protected against hepatitis B after vaccination, without a requirement for boosters, and that the protection is most likely lifelong .
Us Children And Adult Hepatitis B Vaccine Schedules
*Please note that the first dose should be given as soon as possible. Additional doses require minimum time intervals between doses in order for the vaccine to be effective.
3-Dose Vaccine Series for Children and Adults
The hepatitis B vaccine is an injection that is generally given in the arm as a three-dose series on a 0, 1, and 6-month schedule. Alternative schedules may be considered, noting that a third dose at 6 months, meeting minimum intervals between doses, is needed for maximum, long-term protection. Completing the hepatitis B vaccine series, preferably beginning at birth, will ensure protection against hepatitis B, hepatitis delta and lower the lifetime risk of liver cancer. Greater than 90% of babies and up to 50% of young children who are not vaccinated and are infected with hepatitis B will have lifelong infection, which makes the birth dose essential to their protection.
There are four, 3-dose vaccine brands approved in the U.S.
- PreHevbrioPreHevbrio is only approved for adults age 18 and over.
