At this rate it will take 10 years to get natural immunity.
All healthy and not-so-old people should expose themselves to any and all viruses and build herd immunity. Covid has been lethal mainly to people with existing serious health problems. Only those people should be “quarantined” and let the rest go on with life.
IMO we have national natural immunity already. All adults already vaccinated, plus all those already carrying the anti-bodies having had the virus, I believe gives us a huge percentage of the population carrying the anti-bodies and therefore enough for natural immunity.
There will always be a handful to defy the antibodies and come down with covid, and then the pesky illegals who are systematically spreading the virus around the country - mostly red states like Texas and Louisiana. That’s another story!!
