Patient's question:
Doctor, my family took the baby to the health center today for the second dose of the hepatitis B vaccine. After they came back, I noticed that in the "Child Immunization Certificate," the doctor had noted the vaccine manufacturer and batch number as "20080719-4," while the first dose of the hepatitis B vaccine had the doctor's note as "200910A3103."Doctor's answer:
Hello, 200910A3103/20080719-4 is the batch number of the vaccine. You need to consult the staff who administered the vaccine to check when it is valid; the batch numbers of the first and second doses of the vaccine are different, but as long as the manufacturers are the same, it is acceptable.Advice: Hello, please trust our prevention staff. If the vaccine is invalid, our prevention staff would neither dare nor would they use it. If you still have concerns, you can visit the vaccination unit to inquire about the production date and validity period of this batch of vaccine.
