Viruses have yet to be successfully attacked by allopathic medicine. Aside from symptomatic treatment, which does not address the root cause of viral infections, we've relied on plasma generated antibodies arising either naturally or artificially via vaccines to combat viral infections. It is worrisome that a non-trivial number of patients have gone from Covid-19 positive to Covid-19 negative and back to Covid-19 positive. If these "re-infection" tests are picking up different viral strains, then this is only a problem if the virus is mutating too fast for vaccines (or our own B-Cells) to keep up with. But if that's not the case and people are actually being re-infected with the same virus, then this is entirely new. Historically, surviving a viral infection resulted in antibodies to that virus - meaning you couldn't catch the same virus again while these antibodies were present. That may not be the case with Covid-19. It's far from certain, but if it turns out that naturally occurring antibodies are an insufficient defense against re-infection, then that would render out entire strategy of combating viral infections through vaccines utterly useless.
It's an interesting problem. That's all.
