Schedule: All children and teens in the U.S. should get 3 doses of hepatitis B vaccine. Infants should receive the first dose within 24 hours of birth. Many adults are at risk of hepatitis B and should be vaccinated. Adults should receive 2 or 3 doses of hepatitis B vaccine depending on the brand of vaccine.
Hepatitis B is a liver infection caused by the Hepatitis B virus (HBV). Hepatitis B is transmitted when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth. For some people, hepatitis B is an acute, or short-term, illness but for others, it can become a long-term, chronic infection. Risk for chronic infection is related to age at infection: approximately 90% of infected infants become chronically infected, compared with 2%–6% of adults. Chronic Hepatitis B can lead to serious health issues, like cirrhosis or liver cancer. The best way to prevent Hepatitis B is by getting vaccinated.
