I had this test done at Mayo when I was telling my Neph it is hard to know if it is safe after 3 doses of vaccine. She offered to test me for it. I trust the lab test at Mayo far more than any a person can buy themselves. It was called SARS Cov-2 Spike AB.
I agree with you, about all these congressmen, Senators, public figures and others who despite having 2-3 vaccines, are still getting Covid.
I read recently they did a study in Europe and are saying getting too many Covid mRNA vaccines can lower a person’s immune system. Time will tell if they look at that here.
