Coronavirus

[JohnK]

Given that Covid 19 messes with the immune system and it is mostly older folk that suffer the worst effects, it has set me to wondering if any research has/is being done into the possibility of a lifetime of immmunisation weakening the immune system, therefore when an older person that has 50, 60 years and more of being injected with all manner of man made cures for whatever contacts a natural virus such as Covid 19 the immune system has been weakened to such an extent that it cannot deal with it, whereas a younger person whose immune system is still relatively unadulterated suffers a lot less because there the immune system is stronger.

just a thought
