The question I get more than any other:
"I had Covid. I had an antibody test to prove it. Am I protected (and do I need to get the vaccine)?"
Let me start with the usual disclaimer: THIS IS NOT MEDICAL ADVICE. I AM NOT A PHYSICIAN.
But the answer is now increasingly clear: natural immunity from Covid following infection and recovery is HIGHLY protective against future Covid infections. Rates of reinfection are very low.
Perhaps natural immunity eventually wanes, but we don’t know when. In fact, a little-noticed paper from June suggests it may actually strengthen for at least a year - and provide plenty of protection from Delta and other variants.
I am not going into the problems with vaccine-generated protection today or with our political unwillingness to recognize natural immunity. (Remember, GOOD NEWS - we could all use it).
Let’s just look instead at why natural immunity works so well.
