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.
