What is hepatitis A pediatric vaccine?

Hepatitis is a serious disease caused by a virus. Hepatitis causes inflammation of the liver, vomiting, and jaundice (yellowing of the skin or eyes). Hepatitis can lead to liver cancer, cirrhosis, or death.

The hepatitis A pediatric vaccine is used to help prevent this disease in children.

This vaccine works by exposing your child to a small amount of the virus, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body.

Vaccination with hepatitis A pediatric vaccine is recommended for all children who are 12 months of age or older. This vaccine is also recommended in children who travel to certain areas of the world where hepatitis A is a common disease.

Like any vaccine, the hepatitis A pediatric vaccine may not provide protection from disease in every person.

Hepatitis A pediatric vaccine side effects

Get emergency medical help if your child has signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Your child should not receive a booster vaccine if he or she had a life-threatening allergic reaction after the first shot.

Keep track of any and all side effects your child has after receiving this vaccine. When the child receives a booster dose, you will need to tell the doctor if the previous shot caused any side effects.

Call your child's doctor at once if the child has:

• extreme drowsiness, fainting;

• fussiness, irritability, crying for an hour or longer;

• a seizure; or

• high fever (within a few hours or a few days after the vaccine).

Common side effects of hepatitis A pediatric vaccine may include:

• fever;

• irritability, drowsiness;

• loss of appetite;

• headache; or

• swelling, tenderness, redness, or warmth where the shot was given.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report vaccine side effects to the US Department of Health and Human Services at 1-800-822-7967.

Warnings

Your child's doctor may recommend treating fever and pain with an aspirin free pain reliever such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil, and others) when the shot is given and for the next 24 hours.
