Understanding Hepatitis A Vaccine Reactions and Your Right to Compensation

The hepatitis A vaccine is highly effective in preventing a serious viral liver infection. Transmitted through contact with contaminated feces—often via food, water, or close personal contact—hepatitis A can cause severe liver damage and, in rare cases, death.

While most people receive the vaccine without issue, some individuals, including children, may experience side effects. If you’re traveling internationally, especially to regions with high rates of hepatitis A, vaccination is strongly recommended. Keep reading to learn more about the hepatitis A vaccine, its potential side effects, and what to do if you suffer an adverse reaction.

What Is Hepatitis A?

Hepatitis A is a contagious liver infection caused by the hepatitis A virus (HAV). The virus is found in the stool of infected individuals and spreads through:

• Contaminated food or water

• Close contact with an infected person

• Poor sanitation or hygiene

While children are less likely to show symptoms, both adults and children can contract hepatitis A. According to the CDC, common symptoms include:

• Flu-like symptoms (fever, fatigue, nausea, chills)

• Dark-colored urine

• Stomach pain or diarrhea

• Jaundice (yellowing of the skin and eyes)

Who Should Get the Hepatitis Vaccine?

Children typically receive two doses of the hepatitis A vaccine between ages 1 and 2.

Adults should get vaccinated if they:

• Are traveling to high-risk regions (Asia, Africa, Mexico, Central/South America, or Eastern Europe)

• Live with or care for an international adoptee from a high-risk country

• Use injectable illegal drugs

• Are men who have sex with men

• Have chronic liver disease

• Work in labs with hepatitis A or infected primates

People who should not receive the hepatitis A vaccine include:

• Pregnant individuals (unless directed by a physician)

• Those with a current illness

• People with a history of severe allergic reactions to vaccine components like alum or 2-phenoxyethanol

Side Effects of the Hepatitis A Vaccine

The hepatitis A vaccine is administered in two doses: the first dose at least one month before potential exposure, and the second six months later. Most people experience no side effects. However, some individuals may experience:

• Mild flu-like symptoms: Headaches, fatigue, and low-grade fever that last 1–2 days

• Shoulder pain or swelling: Discomfort near the injection site is common; if it persists for over six months, it may be a sign of SIRVA (Shoulder Injury Related to Vaccine Administration)

• Allergic reactions: Rare but serious reactions can occur within hours of vaccination. Warning signs include hives, wheezing, dizziness, fast heartbeat, high fever, or behavioral changes

Can You Get Compensation for a Hepatitis A Vaccine Injury?

Yes. If you’ve suffered a serious reaction, you may be eligible for compensation through the National Vaccine Injury Compensation Program (VICP)—a federal no-fault program that pays medical bills, lost wages, and more to people injured by vaccines.
