Medically reviewed by Drugs.com. Last updated on Dec 2, 2022.
What is the hepatitis A vaccine?
The vaccine is an injection that helps protect your child 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.
When should my child get the hepatitis A vaccine?
The vaccine is given in 2 doses at least 6 months apart. The vaccine can be given with other vaccines.
- Children 12 to 23 months of age should get the vaccine routinely.
- Babies 6 to 11 months old who are traveling outside the U.S. may be given the vaccine.
- Children 2 years and 18 years of age can still get the vaccine, if needed. Talk to your child's healthcare provider about when to get make-up doses.
- Your pregnant adolescent should get the vaccine if she is at risk for hepatitis A. Her healthcare provider will tell you when she should get it.
What increases the risk for hepatitis A?
Your child or adolescent is at increased risk if he or she:
- Was exposed to hepatitis A within the past 2 weeks
- Will be living or travelling internationally
- Will be living in or going to an area where hepatitis A is common or has an active outbreak
- Will be in close contact with a child adopted from another country
- Has a chronic liver disease, HIV, or a weak immune system
