Genel Bilgiler

Vaccination has reduced the number of new cases of hepatitis B by more than 75% in the United States. The hepatitis B vaccine contains a protein (antigen) that stimulates the body to make protective antibodies. Examples of hepatitis B vaccines available in the United States include hepatitis b vaccine-injection (Engerix-B, Recombivax-HB). Three doses (given at 0, 1, and 6 months) are necessary to assure protection.

other vaccine is Gen Hevac B pasteur in Türkiye.

There are also combination vaccines on the market that provide protection against hepatitis B and other diseases. For example:

• hepatitis-b-hepatitis-a-vaccine injection (Twinrix), which provides protection against both hepatitis A and hepatitis B;
  
• Haemophilus B/hepatitis B vaccine - injection (Comvax) provides protection against hepatitis B and Haemophilus influenzae type b (a cause of meningitis)

Hepatitis B vaccines are effective and safe. Up to 95% of vaccinated individuals develop protective antibodies when they get the vaccine and are protected from infection with hepatitis B.

A blood test for hepatitis B antibodies is recommended after vaccination to ensure that antibodies have been produced. For the few who do not form antibodies, revaccination may improve the response, especially in infants. However, a small proportion of individuals will never respond to hepatitis B vaccination. Side effects from the vaccine usually are mild, primarily soreness at the site of injection. The risk of serious allergic reactions (anaphylaxis) is less than one per million doses.
