Patient Education

Hepatitis A Vaccine


Why get vaccinated against hepatitis A? Hepatitis A is a serious liver disease. It is caused by the hepatitis A virus (HAV). HAV is spread from person to person through contact with the feces (stool) of people who are infected, which can easily happen if someone does not wash his or her hands properly. You can also get hepatitis A from food, water, or objects contaminated with HAV. Symptoms of hepatitis A can include the following: fever, fatigue, loss of appetite, nausea, vomiting, and/or joint pain severe stomach pains and diarrhea (mainly in children) jaundice (yellow skin or eyes, dark urine, clay-colored bowel movements) These symptoms usually appear 2 to 6 weeks after exposure and usually last less than 2 months, although some people can be ill for as long as 6 months. If you have hepatitis A you may be too ill to work. Children often do not have symptoms, but most adults do. You can spread HAV without having symptoms. Hepatitis A can cause liver failure and death, although this is rare and occurs more commonly in persons 50 years of age or older and persons with other liver diseases, such as hepatitis B or C. Hepatitis A vaccine can prevent hepatitis A. Hepatitis A vaccines were recommended in the United States beginning in 1996. Since then, the number of cases reported each year in the United States has dropped from around 31,000 cases to fewer than 1,500 cases.
