Dr. McCullough says studies show that getting covid twice is very rare. He says the tests are giving false-positives which make it seem that they are getting it twice, but it is the faulty, inaccurate tests. He mentions another study that people who had the similar SARS-Cov1 (2003) still have immunity 18 years later. So he believes this SARS-Cov-2 (covid 19) will be the same.

I think those studies were done before the vax became available. Those who get covid after the vax may not have the same immunity and maybe are able to become reinfected.

I can't remember if I read it, but it seems that those who have had covid then have worse reactions to the vaccine. So not only do they not need the vaccine, but they actually are more likely to be damaged from it.
