Why is there no electronic vaccination certificate?

The reason for this situation may be that the inoculation point did not provide the voucher seal, so it is necessary to contact the inoculation point or the disease control department for consultation. 1. After vaccination, you can click "Inoculation" on the "Nucleic Acid Vaccine Service Query" page, and click the "Export or Print Inoculation Voucher" button at the bottom of the page to get the voucher download link. 2. Copy the link to the browser to download the electronic vaccination certificate. After vaccination, use the "Health Treasure" button to export the voucher! 3. If you are prompted that the vaccination certificate has not been generated, please try to obtain it again later.
