We have now added the ability to add a third shot or booster for the Pfizer, Moderna and Johnson & Johnson vaccines.
All you need to do is add an additional certificate to your wallet for the information from the third shot like you did for the initial doses or if you have a QR code from a supported provider, scan the QR code and the My Bindle app should add an additional certificate to your wallet.
It's very important to note however that you MUST have additional certificates in your Bindle wallet for your initial vaccination doses in addition to your booster to be able to successfully create an entry pass. When determining if a user is eligible to receive an entry pass, we evaluate both their initial vaccination records AND the booster information. The booster information extends the length of time an entry pass is valid but the initial vaccination information is critical to ensure the validation is successful.
You can find more information about uploading vaccine certificates in this help article.
