Which vaccine is given to prevent hepatitis A?

The hepatitis A vaccine is specifically designed to prevent hepatitis A, a viral infection that primarily affects the liver and is often transmitted through contaminated food and water. This vaccine is effective at inducing immunity against the hepatitis A virus, thereby reducing the risk of infection. It is typically recommended for individuals traveling to areas where the virus is prevalent, as well as for those who may be at higher risk due to their occupation or lifestyle.

Other vaccines listed do not provide protection against hepatitis A. The hepatitis B vaccine targets a different virus responsible for hepatitis B, which is transmitted mainly through blood and bodily fluids. The influenza vaccine protects against influenza viruses, unrelated to hepatitis. The MMR vaccine provides immunity against measles, mumps, and rubella, and does not include coverage for hepatitis A. Thus, the hepatitis A vaccine is the only option that directly addresses the prevention of hepatitis A.
