Who Are Hepatitis B Carriers
Hepatitis B carriers are people who have the hepatitis B virus in their blood, even though they dont feel sick. Between 6% and 10% of those people whove been infected with the virus will become carriers and can infect others without knowing it. There are over 250 million people in the world who are carriers of HBV, with about 10% to 15% of the total located in India. Children are at the highest risk of becoming carriers. About 9 in 10 babies infected at birth become HBV carriers, and about half of children who are infected between birth and age 5 carry the virus. A blood test can tell you if you are a hepatitis B carrier.
Who Should Receive Hepatitis B Vaccination
- All newborns before hospital discharge. Infants born to hepatitis B-positive women need hepatitis B vaccine and HBIG within 12 hours of birth.
- All children and adolescents not previously vaccinated.
- Children born in the U.S. to individuals born in a country with high hepatitis B endemicity.
- All individuals at risk of hepatitis B infection:
- Sex partners of hepatitis B-positive persons
- Sexually active persons who are not in a long-term, mutually monogamous relationship
- Persons seeking evaluation or treatment for a sexually-transmitted disease
- Men who have sex with men
- Persons who inject drugs
- Household contacts of hepatitis B-positive persons
- Persons born in countries where hepatitis B infection is endemic should be tested and vaccinated if susceptible
- International travelers to regions with high or intermediate rates of endemic hepatitis B infection
- Health care and public safety workers that may be exposed to blood or blood-contaminated body fluids
- Residents and staff of facilities for developmentally disabled persons, corrections facilities, and other facilities that serve adults at risk for hepatitis B infection
- Persons with end-stage renal disease, including pre-dialysis, hemodialysis, peritoneal dialysis, and home dialysis patients
- Persons with chronic liver disease
- Persons to age 60 years with diabetes
- Persons with HIV infection
- All other persons seeking protection from hepatitis B infection.
Babies And Hepatitis B Vaccination
Pregnant women have a routine blood test for hepatitis B as part of their antenatal care.
Babies born to mothers infected with hepatitis B need to be given a dose of the hepatitis B vaccine within 24 hours of their birth, followed by further doses at 4, 8, 12 and 16 weeks of age, plus a final dose when they’re 1 year old.
Babies of mothers identified by the blood test as particularly infectious might also be given an injection of HBIG at birth on top of the hepatitis B vaccination to give them rapid protection against infection.
All babies born to mothers infected with hepatitis B should be tested at 1 year of age to check if they have become infected with the virus.

Vaccination Lasts for More Than 10 Years, Italian Study Shows
Oct. 13, 2005 — The hepatitis B vaccine lasts for more than 10 years, so a booster vaccine may not be necessary, Italian researchers report.
“Booster doses of vaccine do not seem necessary to ensure long-term protection,” write Alessandro Zanetti, PhD, and colleagues in The Lancet.
The CDC recommends the hepatitis B vaccine for these groups:
- All babies
- All children aged 0-18 who haven’t already been vaccinated
- People whose behavior or job puts them at high risk for hepatitis B infection
The CDC doesn’t routinely recommend hepatitis B vaccine boosters for people with healthy immune systems.

What Is Involved In A Liver Transplant
A liver transplant is considered necessary when the liver is damaged and cannot function or in some cases of liver cancer. Your liver is very important. It is responsible for many functions related to making sure that your body stays healthy and is able to digest foods.
You may be eligible for a transplant if you have chronic hepatitis B infection or some of the diseases that may result from it, including liver cancer and cirrhosis. You will have to complete testing and be evaluated before being approved for a transplant. It is likely that you will be placed on a waiting list while an appropriate organ is found.
Donated livers come from two types of donors: living and deceased. Because the liver can regenerate, it is possible to use part of a liver for transplant. The remaining sections in both the donor and the receiver will grow into livers of adequate size.
People who get liver transplants must take anti-rejection drugs for the rest of their lives. These drugs make you more susceptible to infection. However, liver transplants have become more successful over time and continue to improve.

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.
Serological Testing After Hepatitis B Vaccination
It is recommended that levels of hepatitis B surface antigen in infants born to mothers with chronic hepatitis B are measured 312 months after they complete the infant vaccine course. Do not test the infant before 9 months of age, to avoid detecting anti-HBs
Post-vaccination serological testing is recommended 48 weeks after completing the vaccine course for:
- people at significant occupational risk, such as healthcare workers whose work involves frequent exposure to human tissue, blood or body fluids
- people at risk of severe or complicated hepatitis B, such as people who are immunocompromised and people with pre-existing liver disease not related to hepatitis B
- people who may respond poorly to hepatitis B vaccination, such as haemodialysis patients and people with bleeding disorders who received the vaccine subcutaneously
- close contacts of people who are infected with hepatitis B virus, including sexual partners, household contacts and household-like contacts22
If serological testing 48 weeks after the vaccine course shows levels of antibody to hepatitis B surface antigen of < 10 mIU per mL, check the person for acute or chronic hepatitis B virus infection by testing for serological markers, including antibodies to anti-HBs and hepatitis B core antigen.
After the booster dose, check for anti-HBs

Can I Catch Hepatitis A From My Husband
Contact with feces of an infected person through sexual activity, including anal sex or oral-anal activity, can result in the spread of hepatitis A to a sexual partner. Even a condom may not be protective, because handling a contaminated condom may lead to spread of the virus onto hands and into the mouth.

Study Design And Subjects
In 2001, healthy adolescents aged between 11 and 15 years were enrolled into a single-blind, randomised, multi-country study conducted in Belgium, Australia and Ukraine. The subjects received either two doses of Engerix-B Adult formulation following a 0, 6 months schedule or three doses of Engerix-B Paediatric formulation following a 0, 1, 6 months schedule . Group HBV_2D additionally received an injection of physiological saline as placebo at second vaccination time point to maintain the blinding. The vaccines were administered as deep intramuscular injections in the deltoid region of the arm .
The study was conducted respecting the Good Clinical Practice guidelines and Declaration of Helsinki. Two of the four centres were eliminated from the evaluation of anamnestic response to the challenge dose the investigator from the study centre was not confident that their team would be able to recruit a sufficient number of subjects and therefore did not participate in this phase of the study while the subjects at another study centre were excluded from the primary analysis due to GCP non-compliance.
