How Long Is the Hepatitis Vaccine Good for?

Hepatitis A is a liver disease than causes flu-like symptoms, yellowing of the skin and eyes, and stomach problems. Because there is no cure for Hepatitis A and the condition can prove deadly in some patients, the Hepatitis A vaccine can prevent the virus's transmission in both children and adults.

When Is the Vaccine Given?

• The Hepatitis A vaccine is considered to be safe in infants 12 months and older. Once the first vaccine is given, a follow-up vaccine should be administered six months later.

How Long Does the Youth Vaccine Last?

• When children receive both doses of the Hepatitis A vaccine, it is expected to provide protection for 14 to 20 years.

Adults Vaccinations

• Certain adult demographics should have a Hepatitis A shot:
  • those who travel to countries with a high population of those with Hepatitis A, such as Mexico, Africa, Central America and others (visit www.cdc.gov/travel for more information on travel vaccines).
  • those who live in areas where cases of Hepatitis A have been diagnosed
  • those with chronic liver disease
  • those who share needles or use street drugs
  • men who have sex with men
  • those who are treated for blood clotting disorders
  • those who work with Hepatitis A (animals or strains) in a laboratory

How Long Adult Vaccinations Last

• Adult vaccinations are given in higher doses and have been shown to last up to 25 years in adults.

Side Effects

• Side effects from the vaccination include mild disorders, such as soreness, headache, appetite loss and tiredness.

Vaccine for Travelers

• Those who are traveling out of the country to Hepatitis A-infected areas, should receive the Hepatitis A shot at least two weeks before traveling out of the country.
