Why vaccination is important

Getting vaccinated is the best way to prevent hepatitis B infection.

Hepatitis B vaccine dosing

Hepatitis B vaccine is a series of two or three shots depending on the vaccine brand.

Missing a dose

If you miss a dose of hepatitis B vaccine, it's okay. Be sure to get the next dose as soon as possible.

Pregnancy considerations

Hepatitis B vaccine is safe for pregnant people. Talk to your doctor about the best option for you.

Boosters are often not necessary

A "booster" dose is an extra dose of vaccine that can increase or extend the effectiveness of the vaccine. Most healthy people do not need a booster dose.

What to expect

If you get the three-shot series, your doctor will give them over a 6-month period. If you get the vaccine that is two doses, you will get them about one month apart. You need to get all of the shots to be fully protected.

Safety and effectiveness

Hepatitis B vaccine is safe and effective. It gives you long-term protection against illness from acute and chronic infection.

Possible side effects

Hepatitis B vaccine is safe, and most people don’t experience any side effects. Soreness at the injection site is the most common side effect.

Available vaccines

There are several types of hepatitis B vaccines available in the United States. Talk to your doctor to determine which vaccine is right for you.
