Hepatitis is an inflammation of the liver, most often caused by a viral infection. There are three common types of hepatitis caused by viruses: hepatitis A, hepatitis B, and hepatitis C. Vaccines have been developed that protect people from contracting hepatitis A and B. There is no vaccine for hepatitis C. Hepatitis A and hepatitis B can be spread from person to person, although in different ways. The vaccination for hepatitis B is given as 3 injections over a 6-month period--an initial dose, followed by a second dose 1 month later, and a third dose 5 months after the second. If you need hepatitis A vaccination in addition to hepatitis B, you can do these individually or as a combined vaccine that covers both. The combination vaccine is given as 3 injections over a 6-month period--an initial dose, followed by a second dose 1 month later, and a third dose 5 months after the second.  Descriptions. Hepatitis A vaccine is used to prevent infection caused by the hepatitis A virus (HAV). The vaccine works by causing your body to produce its own protection (antibodies) against the disease. Hepatitis A is a serious disease of the liver that can cause death.  Hepatitis A vaccine was approved in 2005. PRESCRIBED FOR: Hepatitis A vaccine is used to prevent hepatitis A. Hepatitis A vaccine can be used in persons 1 year of age and older. Although anyone can be infected with hepatitis A, certain people are at high risk and should be routinely vaccinated. DRUG CLASS AND MECHANISM: Hepatitis A vaccine (Havrix, Vaqta) is used to prevent hepatitis A, a type of liver disease that is caused by the hepatitis A virus (HAV). Hepatitis A vaccine is a vaccine against the hepatitis A virus. The first successful vaccine against it was invented by Maurice Hilleman at Merck. The vaccine protects against the virus in more than 95% of cases and provides protection from the virus for at least fifteen years. There are two types of vaccines: one type contains inactivated hepatitis A virus, the other contains a live but attenuated virus. The vaccine should be given in the muscle of the upper arm and be given in two doses for the best protection. The initial dose of the vaccine should be followed up by a booster six to twelve months later. The hepatitis A vaccine is given through a shot. It is approved for use in children (age 1 year and older), teens, and adults. For Havrix ® , the second dose is given 6 to 12 months after the first dose. For Vaqta ® , the second dose is given 6 to 18 months after the first.  Twinrix (GSK) is an inactivated combination vaccine containing both hepatitis A virus (HAV) and hepatitis B virus (HBV) antigens. The vaccine contains 720 EL.U. of hepatitis A antigen (half of the Havrix adult dose) and 20 mcg of hepatitis B antigen (the full Engerix-B adult dose). Yes. Other inactivated and/or live virus vaccines can be administered at the same time as hepatitis A vaccine, but should be given at a different anatomical site, if possible. If given in the same muscle, separate the injections by a minimum distance of 1 inch. 3 Some people should not get hepatitis A vaccine or should wait. • Anyone who has ever had a severe (life threatening) allergic reaction to a previous dose of hepatitis A vaccine should not get another dose.• Anyone who has a severe (life threatening) allergy to any vaccine component should not get the vaccine. • Anyone 1 year of age or older who wants protection from hepatitis A.Hepatitis A vaccine is not licensed for children younger than 1 year of age. WHENFor children, the first dose should be given at 12 through 23 months of age. Children who are not vaccinated by 2 years of age can be vaccinated at later visits. For others at risk, the hepatitis A vaccine series may be started whenever a person wishes to be protected or is at risk of infection
