Is vaccination voucher a personal privacy?

In general, your personal information is very confidential now, and you will not sell your personal information. Generally, the information about vaccination is sent to you by the Health and Epidemic Prevention Department of the National Health and Family Planning Commission. These departments keep personal information relatively confidential, so you basically don't have to worry, and your information will be leaked. I think your personal information is now available in many places in the community and property. Nothing can't be leaked.
