What is the most important information I should know about hepatitis A vaccine?

Hepatitis A vaccine will not protect you against infection with hepatitis B, C, and E, or other viruses that affect the liver. It may also not protect you from hepatitis A if you are already infected with the virus, even if you do not yet show symptoms.

You will most likely receive 2 separate injections of the hepatitis A vaccine at 6 months apart, depending on your exposure or risk of infection. Children should receive their first hepatitis A vaccine between 12 months and 23 months of age.

Your individual booster schedule may be different from these guidelines. Follow your doctor's instructions or the schedule recommended by the health department of the state you live in.

Vaccination with hepatitis A adult vaccine is recommended for all adults who travel in certain areas of the world where hepatitis A is a common disease.

Other risk factors for hepatitis include: being a homosexual male; having chronic liver disease; using intravenous (IV) drugs; receiving treatment for hemophilia or other bleeding disorders; working in a research laboratory or around animals (especially monkeys) where you may be exposed to the hepatitis A virus; or being in an area where there has been an outbreak of hepatitis A.

Be sure you receive all recommended doses of this vaccine. If you do not receive the full series of vaccines, you may not be fully protected against the disease.

You can still receive a vaccine if you have a cold or fever. In the case of a more severe illness with a fever or any type of infection, wait until you get better before receiving this vaccine.

You should not receive a booster vaccine if you had a life-threatening allergic reaction after the first shot.

Keep track of any and all side effects you have after receiving this vaccine. When you receive a booster dose, you will need to tell the doctor if the previous shots caused any side effects.

Becoming infected with hepatitis A is much more dangerous to your health than receiving the vaccine to protect against it. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.

What is hepatitis A vaccine?

Hepatitis is a serious disease caused by a virus. Hepatitis A is spread through contact with the stool (bowel movements) of a person infected with the hepatitis A virus. This usually occurs by eating food or drinking water that has become contaminated as a result of handling by an infected person.

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 adult vaccine is used to help prevent this disease in adults. The vaccine works by exposing you 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 adult vaccine is recommended for all adults who travel in certain areas of the world where hepatitis A is a common disease.

Other risk factors for hepatitis include: being a homosexual male; having chronic liver disease; using intravenous (IV) drugs; receiving treatment for hemophilia or other bleeding disorders; working in a research laboratory or around animals (especially monkeys) where you may be exposed to the hepatitis A virus; or being in an area where there has been an outbreak of hepatitis A.

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