Entirely anecdotal, I believe the immune system is already working at high capacity to stop you from becoming sick from the dozens of fungi, bacteria and viruses you come across on a daily basis.

The biggest metric I have for this is that when I am genuinely sick - with a cold or fever - it seems my body stops keeping things like HPV at bay and I start to see remnants of things like warts I haven’t seen for years start to pop up again - and of course disappear again along with the fever.
