Exactly, we were built by the Lord to be walking laboratories so as to normalize everyone's immunity within a community of people, this was proven when the first settlers came to America and their immune systems infected the American Indians with the viruses from Europe. Herd Infection leads to Herd Immunity. The Tribal Medicine Man believed the Settlers were filled with evil spirits and that's what started the many Indian wars the Colonies had to contend with. You can't jump-street into a vaccine like Edward Jenner did with Small Pox, but his observation had to do with noticing that people with Cow Pox didn't get Small Pox so he gave dead cow pox virus to people and that prevented small pox. Covid19 is nothing more then Influenza and it'll change (mutate) year after year. SARS CoV2 is a laboratory made Bat Corona Virus with a contagious Spike Protein built into it, this never left China and in China, it died. Secondary infection is Covid19, a virion copy that makes a Flu type sickness but recovery is within 14 days.
