Patient's question:
My child is 6 years old. I remember he received an hepatitis B vaccine when he was 2, but I forgot. Coincidentally, my friend's child didn't get a vaccine when he was 2. For convenience, I'd like to check the batch numbers of children's vaccines. Different vaccines have different batch numbers, and I want to know all of them. Who can tell me? If you know, please let me know. Thank you.Doctor's answer:
The batch number on the vaccine label is basically indicated by the production date. For example, 200910A3103/20080719-4 is the batch number of the vaccine. You should consult the staff who administered the vaccine to you. As long as the production unit of the vaccine is the same, it is acceptable. Generally, the validity period of the hepatitis B vaccine is 2 years. If you want to know the detailed information, you can check with the Drug Administration.
