Vidcast: https://youtu.be/rRY3emWBAEo If you weather Covid-19 infection, there is a 99.3% chance that you will avoid a second infection. A collaborative study by investigators at Cornell and Qatar Universities reviewed data from 43,044 CoVid patients. Only 0.7% of this group developed another CoVid-positive PCR test. Only 41% of that tiny group had convincing clinical evidence of a second infection. And these re-infections were less severe than the initial ones. Immunologic testing of this group indicated persistent CoVid immunity for at least 7 months. As more of us attain this immunity from surviving natural infections and, more importantly, via vaccination, there will be fewer new coronavirus infections and less circulating virus in our communities. https://www.medrxiv.org/content/10.1101/2021.01.15.21249731v1.full.pdf #covid #reinfection #immunity
