What Experts Say

Paediatricians across Pakistan encourage the birth dose of Hepatitis B vaccine within 24 hours of delivery, since mother to child transmission is a major route of infection in the region. Shanvac-B is one of the recombinant vaccines used for this purpose in both public and private clinics nationwide.

Infectious disease specialists explain that the vaccine works by training the immune system to recognize a piece of the Hepatitis B virus surface, without exposing the body to the actual virus. A full course, usually three or four doses depending on the schedule, gives the most reliable long term protection against chronic infection.

Doctors also stress that missing doses or delaying the schedule can lower protection, so families are advised to keep the full series on time. Anyone unsure about their vaccination history can ask their doctor about a blood test or a completion schedule tailored to their age and exposure risk.
