Hepatitis A
Hepatitis A is a serious liver disease caused by the Hepatitis A virus (HAV). HAV is found in the stool of persons with Hepatitis A and is spread by close personal contact with an infected person or by eating food or drinking water contaminated with HAV. The incubation period (time you were infected to the time you contract the disease) is from approximately 20 to 50 days. More information.

HAV causes a wide variety of symptoms that range from mild flu-like symptoms to more serious problems such as "yellow jaundice", severe abdominal pains, nausea, diarrhea, and fatigue, possibly requiring hospitalization. In some cases HAV can cause death.

About the Vaccine
HAV is a vaccine-preventable disease. The vaccine is an inactivated whole virus derived from HAV grown in a human cell culture. It is harvested, purified, formalin inactivated (so it cannot give you the disease!), and prepared in a sterile suspension for injection. Side effects of the vaccine can include soreness at the site of injection and fatigue. Severe allergic reactions are rare.

The vaccination schedule includes one injection with a booster dose 6 to 12 months later. Vaccination should be started at least 2 weeks before anticipated exposure to HAV. Immunity appears to be at least 20 years, but there are no studies as of yet to confirm longevity of the immunity.
