Hepatitis A Vaccine for Children


The hepatitis A 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 your child should get the hepatitis A vaccine:

The vaccine is given in 2 doses at least 6 months apart. The vaccine should be given routinely between 12 and 23 months of age. It can be given between 2 years and 18 years of age, if needed. 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. The hepatitis A vaccine can be given with other vaccines.

Call your local emergency number (911 in the US) if:

  • Your child has signs of a severe allergic reaction, such as trouble breathing, hives, or wheezing.

Seek care immediately if:

  • Your child has a high fever or any behavior changes that concern you.

Call your child's doctor if:

  • You have questions or concerns about the hepatitis A vaccine.

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
  • Uses illegal drugs or is a male who has sex with another male

Who should not get the hepatitis A vaccine or should wait to get it:

If your child is sick, wait to get the vaccine until his or her symptoms go away. Do not let him or her get a second dose if he or she had a severe allergic reaction to the first dose.

Risks of the hepatitis A vaccine:

The area where your child got the shot may be sore or tender. This is usually mild and goes away in a few hours. He or she may also have a headache or loss of appetite, or feel tired for up to 2 days. He or she may have an allergic reaction to the vaccine. This can be life-threatening. If your child has severe allergies, including to latex, ask if the vaccine contains ingredients that can trigger an allergic reaction.

Apply a warm compress

to the area where your child got the vaccine to relieve swelling and pain.

Follow up with your child's doctor as directed:

Write down your questions so you remember to ask them during your visits.
