Vaccinations

Hepatitis B is preventable with a vaccine that has been available for over 20 years. The vaccine provides an easy and effective method for preventing Hepatitis B Virus (HBV) infection and its deadly implications. All people, including children, adolescents and adults should be vaccinated provided they are not already chronically infected with HBV. 

The Hep B Vaccine

If both your blood tests (HBsAg and anti-HBs) are negative, you have not been infected with hepatitis B nor are you protected. Get vaccinated to protect yourself.

Your options include 2 FDA approved and CDC recommended vaccines, a 2 shot vaccination series (recommended for adults 18 and older),* or a 3-shot hepatitis B vaccination series**.

Vaccination usually protects you for life. All newborns should receive the hepatitis B vaccine at birth. Ask your medical provider which vaccine is right for you. 

*Approved in 2017, this vaccine is taken in 2 doses, 1 month apart.

**Approved since 1989, this vaccine is taken in 3 doses, the 2nd shot 1 month after the first and the 3rd, 6 months after the first shot.
