Generally speaking, there will be no typographical errors in the QR code scanning system for vaccine boxes.

During the vaccination process, use the electronic supervision code of the vaccine to be vaccinated to scan the code. If the scanned vaccine is correct, the vaccination result will be automatically confirmed; if the scanned vaccine is incorrect, the system will prompt and then restart. Just take out the vaccine with the correct batch number and scan the code.

However, any manual operation may have errors, so if you have any doubts, it is recommended to consult the relevant staff.
