Hepatitis A Vaccine Information
The Hepatitis A vaccine is made from inactive virus and is generally safe. In most cases, there are very few side effects. The most common potential side effect is soreness at or around the injection site. Other potential side effects include mild headache, loss of appetite among children, and fatigue. These side effects usually last 1 or 2 days. However, like any medicine, the Hepatitis A vaccine could cause serious problems, such as an allergic reaction, which may appear within a few minutes or hours after getting the shot. This occurs very rarely, but if you believe you are having a reaction to the vaccine you should call your provider right away.
The National Vaccine Injury Compensation Program may provide compensation for: (1) Shoulder Injury Related to Vaccine, known as SIRVA, which is a sometimes-painful injury to the shoulder where the vaccine was administered, and (2) Vasovagal Syncope, which is when a person faints because his or her body overreacts to certain triggers, such as the sight of blood or extreme emotional distress.
