Question
Will delaying the hepatitis B vaccine injection have an impact? Do I need to go to the hospital for treatment? How long will it take to recover? Please help me!
Answer
It is recommended to follow the vaccination schedule and timeline for the hepatitis B vaccine. Delaying the injection by a few days may affect antibody production. It is still advisable to follow the doctor’s advice when getting vaccinated. In special circumstances, it may be possible to delay the injection by a few days, but it should not exceed a week, as the effect may not be ideal beyond that. As long as there is no significant delay, the hepatitis B vaccine is effective. It is recommended to have your antibodies tested at the hospital after vaccination, as some individuals may not produce enough antibodies and may need to be vaccinated again. The principle of vaccination is not to start early; the interval between two doses must be greater than 28 days, and a few days’ delay is acceptable, such as when encountering contraindications, in which case the vaccination time must be postponed.
