does natural immunity change over time?
-
I know someone who was just diagnosed with COVID for at least the third time, if not 4th time, over the last 2-3 ears and they claim to have never been jabbed. No reason to think they would be lying about the jab. Assuming no jab ever, doesn’t natural immunity make a situation like this highly unlikely? Or is it that some people just have weak natural immunity system and will always be susceptible to newer variants as they move through a population?
