What does the hepatitis A vaccine protect children from?

• A. Measles
• B. Hepatitis A infection
• C. Influenza
• D. Hepatitis B infection

Answer: (B)

Vaccines create targeted immunity against specific pathogens. The hepatitis A vaccine trains the immune system to recognize the hepatitis A virus and develop antibodies that block infection if the person is exposed later. This protection is specific to hepatitis A and does not extend to other viruses or diseases. So, this vaccine is designed to prevent hepatitis A infection. It doesn’t protect against measles, influenza, or hepatitis B, which are caused by different viruses and require their own vaccines.
