Patient's question:
My child was born on 9.24 and received the first dose of the hepatitis B vaccine. The second dose was given on 10.30. Due to a cold, the third dose of the DTP vaccine was administered on 3.12. According to this calculation, the third dose of the hepatitis B vaccine can only be given on 4.09, which means it was delayed by 15 days. Will it still produce antibodies?Doctor's answer:
The full course of the hepatitis B vaccine requires 3 shots, following the 0, 1, 6-month schedule. This means that after the first shot, the second and third shots should be administered 1 and 6 months later, respectively. It is best to administer the hepatitis B vaccine to newborns as early as possible, and it is required to be given within 24 hours after birth. The second and third shots are booster doses for hepatitis B. In normal circumstances, antibodies are usually produced after the first shot. Antibodies will be produced regardless of when the vaccine is administered. Moreover, your child's third shot on April 9th is within the 6-month window, so it is not too late.Advice: Antibodies will be produced, so there is no need to worry. I hope this helps, and I wish your child good health.
