What Experts Say

Infectious disease specialists consider adult hepatitis B vaccination essential for anyone with an ongoing risk of blood or body fluid exposure. Healthcare workers, in particular, are strongly advised to complete the full course. Protection generally develops within weeks of the final dose.

Many adults in Pakistan missed routine hepatitis B vaccination as children, since the vaccine was added to the national program more recently. Doctors now recommend catch up vaccination for this group regardless of age. A blood test can confirm existing immunity before starting the course.

Public health experts emphasize that hepatitis B often causes no early symptoms, allowing the virus to silently damage the liver over years. Vaccination remains the most effective way to prevent this outcome. Completing all recommended doses offers the strongest, most durable protection.
