Basics

What should you do if you are exposed to the hepatitis B virus?

If you know you were recently exposed to the hepatitis B virus, you may get protection from a shot of hepatitis B immunoglobulin (HBIG) within 24 hours after your exposure. This will protect you for three to six months, but it is also strongly recommended that you begin the three-shot hepatitis B vaccine series, starting within seven days of your exposure.
