The natural immunity conferred by having contracted the Chinese virus and recovered should last decades. Antibody testing is a short term thing, it won’t necessarily show the antibodies for more than a few months. I think they have to test for certain T and B cells or somesuch. This is the body “memory” of the specific virus, and is ready in reserve should it be exposed again down the road.
Why they are playing these games is inexplicable. If someone has natural immunity, it is not necessarily a good idea at all to take that particular vaccine. Why take the chance? The Chinese virus can really screw people up, but then, so can the vaccine.
Post-infection natural immunity is against the entire virus, not just the ever-changing spike protein. Of course natural immunity is better and longer lasting than these type of spike protein only gene therapy shots. There is no reason for the shots if someone already has natural immunity and all the shot could do is cause havoc, perhaps ADE or autoimmune attack. Sheesh, I want to slap someone, like Fraudci.
