According to experts ( the real ones, like Dr Peter McCullough) it is so rare to catch covid twice that is statistically an anomaly.
More likely some people get covid and do not completely clear the virus…it remains latent ( like HIV) and then can reemerge. This seems to occur in some people after they take the vaccine.
Yes one of the big lies is that you can get COVID 2x. According to Dr. McCullough most of those that get COVID 2x are the result of false positives.
As we have discovered the test for COVID was amplified to such an extent that any virus detected would appear as COVID, which is also why there were virtually no flu cases last year.
Likely someone that claims they have gotten COVID a second time actually had something else one of those times.
