How safe is Hepatitis A vaccine? Does it have any side effects?

Many studies have shown that Hepatitis A vaccine is very safe. Since 1995, more than seven million doses of Hepatitis A vaccine have been given in the U.S. with no report of serious health problems linked to the vaccine. Side effects might include soreness at the injection site, headache, and tiredness. These symptoms, if they occur, last for only a short time.
