Hey 02Hook,
Sounds like you're having an issue where the QR code you scanned for your vaccine records to upload to the Health app is showing the wrong vaccine. We can certainly understand the concern and are happy to help!
The resource you came from, Add verifiable COVID-19 vaccination information to Apple Wallet and Health, indicates that this QR code is provided by the COVID-19 vaccination or test provider. Because of this, if you're having issues with the information being provided by them, it'd be best to get back in contact with them and let them know that the QR code you were provided has incorrect information.
Apple is not part of the third party’s verification process and will not have access to this data...
We hope this information helps out!
Take care.
