Hepatitis A Vaccine
WHAT YOU NEED TO KNOW:
What is the hepatitis A vaccine?
The vaccine is an injection that helps protect you from the virus that causes hepatitis A. Hepatitis A is a serious liver disease. The virus is usually spread by person-to-person contact or through food and liquid contaminated with the virus. The vaccine is given in 2 or 3 doses. The vaccine can be given with other vaccines.
Who should get the hepatitis A vaccine?
You may need the hepatitis A vaccine if:
- You have a chronic liver disease or HIV.
- You are a man who has sex with men.

What are the risks of the hepatitis A vaccine?
The area where you got the shot may be sore or tender. This is usually mild and goes away in a few hours. You may also have a headache, loss of appetite, or feel tired for up to 2 days.
