Although Hepatitis A does not cause chronic liver disease like Hepatitis B or C, it can still have serious effects on the body — especially in individuals who already have existing liver conditions.
Getting vaccinated against Hepatitis A is a safe and effective way to prevent infection, reduce the risk of transmission, and allow you to live with confidence — without worrying about this disease.

What is the Hepatitis A vaccine?
The Hepatitis A vaccine is an inactivated (killed) virus vaccine that helps prevent infection caused by the Hepatitis A virus — a contagious virus that affects the liver and is commonly transmitted through the digestive tract. It is a safe and effective way to protect yourself from Hepatitis A infection.
Who should get the Hepatitis A vaccine?
People Who Should Receive the Vaccine
Certain groups are at higher risk of contracting Hepatitis A and should consider vaccination:
- Travelers to areas where Hepatitis A is common (should get vaccinated at least 1 month before travel)
- People living in areas experiencing an outbreak
- Individuals in close contact with someone infected with Hepatitis A
- People who use recreational drugs
- Patients with chronic liver disease
- People who require frequent blood transfusions
- Healthcare and laboratory personnel
- Food handlers and restaurant workers
- Military personnel
- Men who have sex with men (MSM)
People Who Should Avoid the Vaccine
-
Those with a history of severe allergic reaction to a previous Hepatitis A vaccine dose or to any component of the vaccine
-
Individuals who are currently infected with the Hepatitis A virus
-
People with a high fever or severe acute illness should postpone vaccination until recovery (however, those with mild illness and no fever can still receive the vaccine)

What are the side effects of the Hepatitis A vaccine?
Side effects are generally mild and usually resolve within 1–2 days, such as low-grade fever, pain, swelling, and redness at the injection site. Other possible side effects include loss of appetite, headache, dizziness, nausea, diarrhea, and muscle aches.
Is the Hepatitis A vaccine necessary?
Hepatitis A infection can cause liver damage. Infected individuals may experience no symptoms or severe illness, and people of all ages—from young children to the elderly—can be affected.
The virus spreads easily through contaminated food and water or contact with surfaces carrying the virus.
Therefore, vaccination is an effective and necessary method of prevention, especially for those at higher risk of exposure or transmission.
Do you need a booster dose after getting the Hepatitis A vaccine?
If you receive the full 2-dose Hepatitis A vaccine series, it provides 100% effectiveness in generating immunity against infection.
This protection can last for over 20 years, or even a lifetime, so no booster dose is necessary.
