Which statement correctly describes the Hepatitis B vaccination schedule?

• A. It requires two doses over three months
• B. It requires three doses over six months
• C. It requires one dose
• D. It requires four doses over a year

Answer: (B)

Protecting against hepatitis B relies on a vaccine series that builds and boosts the immune response through multiple exposures. The standard approach is three injections given over several months to achieve durable protection. For infants, the typical schedule is at birth, then at about 1–2 months, and again at 6–18 months, totaling three doses over roughly six months. Completing all three doses is essential because a single dose doesn’t provide reliable protection, and two doses aren’t considered complete for routine immunization. Four doses over a year isn’t the usual routine schedule, though some accelerated regimens exist in special situations.
