Let's Talk About Ceps
And you're still not getting the point about herd immunity. It's not some arbitrary number; it does vary from disease to disease but it does have to be *most* people.
"Based on early estimates of this virus’s infectiousness, we will likely need at least 70% of the population to be immune to have herd protection." (Johns Hopkins)
"Researchers think that the R0 for COVID-19 is between 2 and 3. This means that one person can infect two to three other people. It also means 50% to 67% of the population would need to be resistant before herd immunity kicks in and the infection rates start to go down." (WebMD - slightly lower estimate, but it's still at least half, and it's still an order of magnitude that England's current rate of 6.3%)
"Even if infection with the COVID-19 virus creates long-lasting immunity, a large number of people would have to become infected to reach the herd immunity threshold. Experts estimate that in the U.S., 70% of the population — more than 200 million people — would have to recover from COVID-19 to halt the epidemic." (Mayo Clinic - which also points out that relying on natural herd immunity might be a really bad idea for this disease, since "it isn't yet clear if infection with the COVID-19 virus makes a person immune to future infection.")
