Hepatitis B vaccine is a vaccine to prevent hepatitis B. The first dose is recommended within 24 hours of birth with either two or three more doses given after that. This includes those with poor immune function such as from HIV/AIDS and those born premature. In healthy people routine immunization results in more than 95% of people being protected.Additional doses may be needed in people with poor immune function. In those who have been exposed to the hepatitis B virus but not immunized, hepatitis B immune globulin should be given in addition to the vaccine. The vaccine is given by injection into a muscle.Serious side effects from the hepatitis B vaccine are very uncommon. Pain may occur at the site of injection. It is safe for use during pregnancy or while breastfeeding. It has not been linked to Guillain–Barré syndrome. The current vaccines are produced with recombinant DNA techniques. They are available both by themselves and in combination with other vaccines.
The first hepatitis B vaccine was approved in the United States in 1981.A safer version came to market in 1986. It is on the World Health Organization’s List of Essential Medicines, the most effective and safe medicines needed in a health system. As of 2014, the wholesale cost in the developing world is US$0.58–13.20 per dose.In the United States it costs US$50–100.
