My first two COVID shots were Pfizer and I chose Moderna as my booster back in November 2021. Why is my booster still not showing up on my digital vaccination card today 3/3/2022?

I don’t know if this will work for you, but this is what I did.

I received my booster in August of 2021. All three of the vaccinations were Pfizer. However, my third shot was issued by a different provider than my first two shots which were give to me by my health provider. I struggled for a number of months trying to get the third shot to show up on my Apple Wallet vaccination card. I took a photo of my Covid vaccination card and sent it to my health care provider. They were able to plug the information into their system and I was than able to use the code to add the updated card to my Apple Wallet and into the health app.

You may need to contract your COVID-19 vaccination or test provider.
