What is the routine dosing schedule for Hep B vaccination?

• A. Day 0, Day 7, Day 21
• B. Day 0, Day 30, Day 180
• C. Day 0, Day 14, Day 28
• D. Day 0, Day 60, Day 180

Answer: (B)

Hepatitis B vaccine is given as a three-dose series to build long-lasting protection, with specific minimum time between doses. The first dose is started at day 0, then the second dose is given after about a month, and the third dose is given around six months after the first. This spacing meets the required minimum intervals (at least 4 weeks between the first and second doses and at least 8 weeks between the second and third, with the third dose no earlier than 16 weeks after the first). The schedule that shows Day 0, Day 30, and Day 180 fits this recommended timing and aligns with the typical routine plan of 0, 1 month, and 6 months. The other options place doses too close together and don’t reflect the standard timing for a routine Hep B vaccination series.
