What is the most effective strategy to prevent hepatitis B infection?

• A. Vaccine
• B. Barrier protection during intercourse
• C. Covering open sores
• D. Avoid sharing toothbrushes

Answer: (A)

Preventing hepatitis B infection is best achieved through vaccination. The hepatitis B vaccine prompts the body to develop protective antibodies, producing long-lasting immunity that can prevent infection before exposure occurs. While barrier protection during sexual activity reduces risk, it does not eliminate all routes of transmission such as exposure to infected blood or fluids in other settings. Covering open sores or avoiding sharing toothbrushes may lower some risk, but they’re not dependable primary strategies because hepatitis B can spread through multiple routes and exposures can be unconscious. Vaccination provides the strongest, most comprehensive protection overall.
