Funny how the COVID deniers/anti-vaxxers get all crazy about there being no long term safety data for the vax but then are suddenly certain that there couldn't possibly be any long term implications for COVID infections. There is a growing body of evidence that natural COVID infection can weaken the immune system with some parallels to HIV. Worse still, there is evidence that recent infection with Omicron provides no protection from B.A4 and 5 variants due to the immune escape those variants have against earlier Omicron variants. The good news is that B.A4 and 5 have not been producing nearly as much hospitalizations and death. But COVID infections may be weakening immune systems and setting the stage for less resistance to future COVID infections. That is a scary prospect that is unique to COVID.
