I mean, we probably can’t be immune to 100 trillion diseases because that’s more than the number of cells in the body. So is it more likely that our immune system can recognize closer to 50 diseases? 100 diseases? 1,000,000 diseases?
The fact that organisms can mutate/evolve is irrelevant because the question is about the “memory” capacity of the immune system
