Talk to your health care professional for more details.

Before receiving this vaccine, tell your health care professional your medical history, especially of: current illness with fever.

If you have immune system disorders (such as due to HIV infection, certain cancers such as leukemia/lymphoma, cancer or radiation treatment), your body may not make enough antibodies to protect you from hepatitis A infection. Antibody levels should be checked after the vaccine series.

During pregnancy, this vaccine should be used only when clearly needed. Discuss the risks and benefits with your health care professional.

Hepatitis A spreads very easily, often through contaminated food or water, infected food handlers, sexual contact with an infected individual, eating raw shellfish from contaminated water, poor sanitary conditions, and rarely by blood transfusions or sharing needles with actively infected people.

Keep vaccine records for yourself and all of your children, and after your children are grown provide their records to them and their health care professionals. This will prevent unnecessary re-vaccinations.
