Inactivated Hepatitis A Vaccine

Inactivated Hepatitis A Vaccine, also known as Havrix or Vaqta, is an injectable medication that protects against hepatitis A, a contagious liver infection caused by the hepatitis A virus (HAV). This vaccine is made from inactivated or “killed” virus particles, which cannot cause the disease but stimulate the body’s immune system to produce an effective response.
The vaccine is a combination of two doses given at 0 and 6-18 months for the initial vaccination series, with a second dose administered 6 to 12 months after the first to provide long-lasting immunity. Certain high-risk groups, such as people with chronic liver disease, homosexual men, and travelers to high-risk areas, may receive additional doses or booster shots.
Inactivated Hepatitis A Vaccine is generally well-tolerated, but possible side effects may include pain and redness at the injection site, fever, headache, and fatigue. Severe allergic reactions to the vaccine are rare but can occur. As with any medication, it’s essential to consult with a healthcare provider to determine the appropriate course of action based on an individual’s medical history and risk factors.
