How Many Doses Of Hepatitis B Vaccine For Adults

How To Get Vaccinated Against Hepatitis B

Hepatitis B Vaccine

All babies in the UK born on or after 1 August 2017 are given 3 doses of hepatitis B-containing vaccine as part of the NHS routine vaccination schedule.

These doses are given at 8, 12 and 16 weeks of age.

Babies at high risk of developing hepatitis B infection from infected mothers are given extra doses of the hepatitis B vaccine at birth, 4 weeks and 1 year of age.

If you think youre at risk and need the hepatitis B vaccine, ask your GP to vaccinate you, or visit any sexual health or genitourinary medicine clinic.

If your job places you at risk of hepatitis B infection, its your employers responsibility to arrange vaccination for you, rather than your GP. Contact your occupational health department.

Accelerated 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.

In some instances, it may be necessary to vaccinate within a short period of time to ensure protection before travel. There are accelerated schedules to provide the highest level of protection over a short period of time. Individuals who need an accelerated schedule must have a booster dose at 1 year to ensure long-term protection. Note that the 2-dose Heplisav-B vaccine will also ensure maximum protection over a 1-month period without the need for a booster dose at 1 year.

4-Dose Vaccine Series for Children and Adults

Engerix-B is a 3-dose vaccine that can be given on an accelerated, four-dose schedule, with 3 shots administered within 2 months, and a booster dose at 1 year to provide maximum long-term protection.

4-Dose Combination Hepatitis A and B Vaccine Series

Twinrix is a 4-dose vaccine that can be given on an accelerated schedule to provide protection against hepatitis A and B. Three doses are administered within 1 month, followed by a booster shot at 1 year. This is a common choice of vaccine for those travelling on short-notice outside the U.S. It is important to complete the booster dose at 1 year, to ensure long-term protection.

Why Is The Hepatitis B Vaccine Important

Because of the vaccine, cases of acute hepatitis B have decreased by a lot in the United States. But chronic hepatitis B is still common up to 2.2 million people in the United States have it. Chronic hepatitis B can lead to serious liver problems and even death.

Getting vaccinated is the best way to prevent hepatitis B.

Hepatitis B is a liver disease caused by a virus. There are 2 types of hepatitis B:

  • Acute hepatitis B
  • Chronic hepatitis B

Many children who get acute hepatitis B dont have any symptoms, but most adults do. Symptoms may include:

  • Dark pee or clay-colored poop
  • Pain in the muscles, joints, and stomach

Acute hepatitis B symptoms usually last a few weeks but they can last as long as 6 months.

If the acute hepatitis B infection does not go away after 6 months, its considered a chronic hepatitis B infection. Most people who have chronic hepatitis B dont have symptoms at first. But chronic hepatitis B is a lifelong illness that can lead to serious and possibly deadly liver problems, like:

  • Has sex with a person who has hepatitis B
  • Touches the blood or open sores of a person who has hepatitis B

All children and most adults need to get the hepatitis B vaccine.

Infants and children

All children need to get the hepatitis B vaccine as part of their routine vaccine schedule.

Children need 3 doses of the vaccine at the following ages:

  • Birth for the first dose
  • 1 through 2 months for the second dose
  • 6 through 18 months for the third dose

Adults

Selected Safety Information For Recombivax Hb Selected Safety Information For Recombivax Hb

Do not administer RECOMBIVAX HB® to individuals with a history of severe allergic or hypersensitivity reactions after a previous dose of any hepatitis B-containing vaccine or to any component of RECOMBIVAX HB, including yeast.

The vial stopper and the syringe plunger stopper and tip cap contain dry natural latex rubber, which may cause allergic reactions in latex-sensitive individuals.

Apnea following intramuscular vaccination has been observed in some infants born prematurely. Decisions about when to administer an intramuscular vaccine, including RECOMBIVAX HB, to infants born prematurely should be based on consideration of the individual infants medical status and the potential benefits and possible risks of vaccination. For RECOMBIVAX HB, this assessment should include consideration of the mothers hepatitis B antigen status and high probability of maternal transmission of hepatitis B virus to infants born to mothers who are HBsAg positive if vaccination is delayed.

Hepatitis B vaccination should be delayed until 1 month of age or hospital discharge in infants weighing < 2000 g if the mother is documented to be HBsAg negative at the time of the infants birth. Infants weighing < 2000 g born to HBsAg positive or HBsAg unknown mothers should receive vaccine and hepatitis B immune globulin in accordance with ACIP recommendations if HBsAg status cannot be determined.

Vaccination with RECOMBIVAX HB may not protect all individuals.

What Are Side Effects Of Inactivated Viral Vaccines

Side effects of inactivated viral vaccines may include the following:

  • Injection site reactions include:
  • Triggering of shingles in pre-exposed individuals
  • Precipitation or aggravation of autoimmune disorders such as multiple sclerosis
  • Information contained herein is not intended to cover all possible side effects, precautions, warnings, drug interactions, allergic reactions, or adverse effects. Check with your doctor or pharmacist to make sure these drugs do not cause any harm when you take them along with other medicines. Never stop taking your medication and never change your dose or frequency without consulting your doctor.

    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 doctorâs 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 theyâre born. They will also need follow-up blood tests to make sure theyâre OK.

    Catch-up vaccinations are recommended for children and teens who were never vaccinated or who did not get all three shots.

    If you’re 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.

    How Common Is Hepatitis B

    One U.S. study following trends in hepatitis B infection over a three-year periodfound that 4.3% of the population had a past or present HBV infection.

    Estimates suggest that about 240 million people around the world have chronic hepatitis B. Up to 1.89 million people in the United States have a chronic HBV infection.

    Why Should I Vaccinate My Newborn Child If I Know That I Am Not Infected With Hepatitis B Virus

    Before the hepatitis B vaccine, every year in the United States about 18,000 children were infected with hepatitis B virus by the time they were 10 years old. This statistic is especially important because people are much more likely to develop liver cancer or cirrhosis if they are infected early in life, rather than later in life .

    About 9,000 of the 18,000 children infected in the first 10 years of life caught the virus from their mother during birth. However, many young children didn’t catch the disease from their mother. They caught it from either another family member or someone else who came in contact with the child. Because hepatitis B can be transmitted by relatively casual contact with items contaminated with the blood of an infected person, and because many people who are infected with hepatitis B virus don’t know that they have it, it is virtually impossible to be “careful enough” to avoid this infection.

    For these reasons, all young children are recommended to receive the hepatitis B vaccine. The best time to receive the first dose is right after birth. This will ensure that the child will be protected as early as possible from catching hepatitis B from people who dont know that they are infected with the virus.

  • How Is The Hepatitis B Vaccine Made

    How many hepatitis vaccines are there? | Dr. Vachan S Hukkeri | CARE Hospitals

    People are protected against hepatitis B virus infection by making an immune response to a protein that sits on the surface of the virus. When hepatitis B virus grows in the liver, an excess amount of this surface protein is made. The hepatitis B vaccine is made by taking the part of the virus that makes surface protein and putting it into yeast cells. The yeast cells then produce many copies of the protein that are subsequently used to make the vaccine. When the surface protein is given to children in the vaccine, their immune systems make an immune response that provides protection against infection with the hepatitis B virus.

    The first hepatitis B vaccine was made in the 1980s by taking blood from people infected with hepatitis B virus and separating or purifying the surface protein from the infectious virus. Because blood was used, there was a risk of contaminating the vaccine with other viruses that might be found in blood, such as HIV. Although contamination with HIV was a theoretical risk of the early, blood-derived hepatitis B vaccine, no one ever got HIV from the hepatitis B vaccine. That is because the blood used to make vaccine was submitted to a series of chemical treatments that inactivated any possible contaminating viruses. Today, there is no risk of contaminating the vaccine with other viruses because the surface protein is manufactured in the laboratory.
