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 is 15 days late. 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 the first shot is given, and then the second and third shots are administered 1 and 6 months later, respectively. It is best for newborns to receive the hepatitis B vaccine as early as possible, and it is recommended to be vaccinated within 24 hours of birth. The second and third shots are booster doses for hepatitis B. In normal circumstances, antibodies are usually produced after the first shot. The vaccine will produce antibodies regardless of when it is administered. Moreover, your child's third shot on April 9th was given within the six-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.
