Have you ever read the Americans with Disabilities Act (ADA)? The Act offers EXTENSIVE protections for people with disabilities traveling on private transportation that’s open to the public (air, rail, taxi, etc). It makes it very difficult to discriminate on the basis of medical infirmity.
But, even setting aside the profound problems the ADA presents for this system, what’s the enumerated power that allows the federal government to establish a database of your medical history?
How would that medical history collection not be a violation of the 4th Amendment?
In my post I acknowledged that disability would be an exception. It would also be a violation if the employer only required women or people over 50 to be vaccinated, but that's a civil rights violation.

I haven't thought much about it but I'd say tracking vaccination status during a pandemic could be good for the general welfare of the nation.

At least in my state the vaccine consent I agreed to explicitly allows my health care provider to give my vaccine status to the state and the state to share it with the federal government.
The 4th doesn't apply to information freely offered by the individual and no government in the US is mandating the vaccine as far as I know.
