I logged in just to clarify a couple things. The first few posts mention the CDC's tracking. The information being passed to the CDC has all of its personal identifying information removed. The CDC will not have your name and will not be able to verify your vaccination status.
Almost every state for many many years has had a state wide vaccine registry. I dealt with those in Ohio [

The state collected names and date of birth plus some other data such as vaccinating office for every vaccine given in public health clinics and voluntarily from private offices. This data was very useful for school vaccine records and for patients who moved often and did not retain their vaccine records as I could look at the child's records and know what shots had been given and what was needed. The Covid data is piggy-backing on this system and is nothing new.
