Is an immune system more like a tire or a muscle when it comes to wear and tear? I’m an engineer so I have zero medical expertise, but I thought that antibodies make you more resilient to a particular disease and getting sick is the usual way to get antibodies.
- tehjoker 4y agoThe particular biology of sars2 is concerning. It has a super antigen, supresses mhc1, and is very fast and stealthy. Long covid is very real. A recent study found vaccination only protects against it by 15%. Another major study found serial reinfection incurs significant risks each infection. A. Leonardi hypothesizes that naive T cells are protective. Older people have fewer. Hyperstimulation due to antigen will cause the process from naive to effector to proceed and over time deplete that population. In any case, COVID is slightly better controlled with vaccination to the point where it doesn't outright kill you, but that doesn't mean that with a seatbelt I'm looking to crash my car on the reg. You don't walk away healthier each time.
