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 infection 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 A infection can cause illness that leads to loss of appetite; diarrhea and vomiting; tiredness; jaundice (yellow skin or eyes); or pain in the muscles, joints, and stomach. It can also cause long-term illness that can lead to liver damage (cirrhosis), liver cancer, and death.

Hepatitis A vaccine exposes you to a small amount of the virus and helps your body develop immunity to the 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 research laboratories 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.

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.

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 research laboratories 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.

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.

Be sure to receive all doses of the hepatitis A vaccine recommended by your healthcare provider or by the health department of the state you live in. If you do not receive the full series of vaccines, you may not be fully protected against the disease.

Serious side effects from hepatitis A vaccine are very unlikely to occur. Getting hepatitis A virus is a much more dangerous risk to your health than the small chance that you will have a serious side effect from the hepatitis A vaccine.

What should I discuss with my healthcare provider before receiving 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.

Before receiving hepatitis A vaccine, tell your doctor if you are allergic to any drugs, or if you have:

• a bleeding or blood clotting disorder, such as hemophilia;

• any condition that weakens the immune system (such as HIV, AIDS, or cancer); or

• if you are receiving steroids, chemotherapy, or radiation treatments.

If you have any of these conditions, you may not be able to receive this vaccine, or it may need to be postponed until you are in better health.

You may still receive this vaccine if you have a minor illness such as a cold. If you are severely ill or have a high fever, wait until you are feeling better before receiving the hepatitis A vaccine.
