How Many Doses For Hepatitis B Vaccine

Hepatitis B Is Preventable With Safe And Effective Vaccines

Health ministry unveils 1.7 million doses of Hepatitis B vaccine

Immunization is the primary tool for prevention of hepatitis B virus infection. Given that infections acquired in infancy or childhood are more likely to become chronic than those acquired at an older age, reaching younger groups with timely vaccination and with at least 3 doses of hepatitis B vaccine is the core strategy for prevention.Additional measures such as screening of blood donations, provision of sterile injecting equipment and assuring infection control, and promotion of safer sex practices are also important aspects of a comprehensive plan for prevention and control of hepatitis B.

Dose And Administration Of Hepatitis B Vaccine

The dose for Engerix-B and Recombivax HB is 0.5 mL IM up to age 20 years or 1 mL IM for adults . The dose for HepB-CpG is 0.5 mL IM for adults 18 years.

The vaccine is typically given to children in a 3-dose series at age 0 months, at 1 to 2 months, and at 6 to 18 months.

Infants who did not receive a dose a birth should begin the series as soon as feasible.

All children not previously vaccinated with HepB vaccine should be vaccinated at age 11 or 12 years. A 3-dose schedule is used the first and second doses are separated by 4 weeks, and the third dose is given 4 to 6 months after the second dose. However, a 2-dose schedule using Recombivax HB can be used the second dose is given 4 to 6 months after the first.

Adults age 19 through 59 years who have not been previously vaccinated should complete a 2- or 3-, or 4-dose series. The usual schedule for adults using Engerix-B or Recombivax HB is a 3-dose series with 2 doses separated by 4 weeks, and a third dose 4 to 6 months after the second dose. HepB-CpG is given in 2 doses at least 4 weeks apart and can be given as a substitute in a 3-dose series with a different HepB vaccine.

HepB-CpG should not be given during pregnancy because safety data are not available on its use during pregnancy.

Unvaccinated adults who are being treated with hemodialysis or who are immunocompromised should be given 2 doses of Engerix-B 20 mcg/mL given simultaneously in a 4-dose schedule at 0, 1, 2, and 6 months.

Hepatitis B Vaccine Schedule: Standard Accelerated And Combination

Getting poked with a needle is never fun, but its an extremely important part of protecting yourself and others from infectious diseases! The hepatitis B vaccine is known to be one of the most effective vaccines in the world and very safe too! As a blood-borne disease that typically has no symptoms, hepatitis B can easily be spread by accident simply because people are unaware that they have it! Modes of transmission include mother-to-child during birth, unprotected sex, injection drug use, unsafe medical procedures, and the sharing of personal items that may contain blood remnants, such as body jewelry, razors, and toothbrushes. Although certain precautions can be taken to prevent transmission, the only way to completely protect yourself is to get vaccinated. Once you have been vaccinated, you are protected for life!

There are a few options for receiving the hepatitis B vaccination. In most countries, the vaccine is available through a doctors office or a health clinic. The most common option is the standard three-dose vaccine. This consists of three separate doses of the vaccine given through intramuscular injections. In order for the vaccine to be effective, there must be a minimum amount of time between doses. If the minimum amount of time is not followed, the vaccine will not provide full, long term protection from the infection.

3 Dose Schedule:

2-Dose Schedule :

  • 1st shot At any given time
  • 2nd shot At least 28 days after the first shot.

*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.

The hepatitis B vaccine is an injection that is generally given in the arm and as a three-dose series. The World Health Organization recommends a 0, 1, and 6-month vaccine schedule, though schedules may vary based on a countrys national immunization program. 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. Please note that the vaccine brand name, manufacturer and associated schedules for adults, children and infants may be unique to different countries, though there is a list of WHO prequalified vaccines.

3-Dose Vaccine Series for Infants

The World Health Organization recommends all infants receive the first dose of the hepatitis B vaccine within 24 hours of birth and to complete the vaccine series with additional shots at 1 month and 6 months of age. Beginning the hepatitis B vaccine at birth will ensure protection against hepatitis B for life.

    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:

    Does The Hepatitis B Vaccine Have Side Effects

    Some children will develop pain or soreness in the local area of the shot, and low-grade fever.

    There is one extremely rare, but serious, side effect. About 1 out of every 600,000 doses of the hepatitis B vaccine will cause a severe allergic reaction, called anaphylaxis, with symptoms including swelling of the mouth, difficulty breathing, low blood pressure or shock. Anaphylaxis usually occurs within 15 minutes of receiving the vaccine. Although anaphylaxis can be treated, it is quite frightening. People should remain at the doctors office for about 15 minutes after getting the vaccine.

    Although the hepatitis B vaccine is made in yeast cells, no one has ever been shown to be allergic to the yeast proteins contained in the hepatitis B vaccine .

    Is It Okay To Get An Extra Dose Of Hepatitis B Vaccine

    Association of Number of Doses With Hepatitis B Vaccine Series ...

    Yes. Although extra doses of vaccine are not recommended, you can think of the extra dose as another chance for the immune system to see the hepatitis B virus. A vaccine is not the only time the immune system will see the virus or bacteria contained in it. People may be exposed to the virus or bacteria at school or the store or when visiting family or friends. An extra dose of vaccine is like one more exposure, except the difference is that the virus or bacteria in any vaccine has been made safe, so it wont make you ill.

    How Is The Hepatitis B Vaccine Made

    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.

    Hepatitis B Vaccination Schedule For Children And Infants

    The Centers for Disease Control and Prevention recommends that babies and children receive three 0.5 milliliter doses of either Engerix-B or Recombivax HB, starting just after birth.

    The current recommended hepatitis B vaccine schedule for children and infants is as follows:

    Hepatitis B Vaccination Schedule for Infants and Children
    Hepatitis B Vaccine Dose
    3 618 months old

    If your child is undergoing hemodialysis, your healthcare provider may recommend that they receive additional doses of the HBV vaccine.

    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.
