1. WHY GET VACCINATED?
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:
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 U.S. has dropped from around 31,000 cases to fewer than 1,500 cases.
2. HEPATITIS A VACCINE
Hepatitis A vaccine is an inactivated (killed) vaccine. You will need 2 doses for long-lasting protection. These doses should be given at least 6 months apart.
Children are routinely vaccinated between their first and second birthdays (12 through 23 months of age). Older children and adolescents can get the vaccine after 23 months. Adults who have not been vaccinated previously and want to be protected against hepatitis A can also get the vaccine.
You should get hepatitis A vaccine if you:
Ask your healthcare provider if you want more information about any of these groups.
There are no known risks to getting hepatitis A vaccine at the same time as other vaccines.

4. RISKS OF A VACCINE REACTION
With any medicine, including vaccines, there is a chance of side effects. These are usually mild and go away on their own, but serious reactions are also possible.
Most people who get hepatitis A vaccine do not have any problems with it.
Minor problems following hepatitis A vaccine include:
If these problems occur, they usually begin soon after the shot and last 1 or 2 days.
Your doctor can tell you more about these reactions.
Other problems that could happen after this vaccine:
As with any medicine, there is a very remote chance of a vaccine causing a serious injury or death.
The safety of vaccines is always being monitored. For more information, visit: www.cdc.gov/vaccinesafety/

What should I do?
VAERS does not give medical advice.
6. THE NATIONAL VACCINE INJURY COMPENSATION PROGRAM
The National Vaccine Injury Compensation Program (VICP) is a federal program that was created to compensate people who may have been injured by certain vaccines.
Persons who believe they may have been injured by a vaccine can learn about the program and about filing a claim by calling 1-800-338-2382 or visiting the VICP website at www.hrsa.gov/vaccine-compensation/index.html There is a time limit to file a claim for compensation.
