Also, with the vaccine we can now start to approach "herd immunity" as the concept was initially intended -- 60-70% exposure and inoculation through vaccination rather than the definition that has been employed recently by Dr. Atlas and others as 60-70% immunity through contracting the virus. It will take a long time to reach the 60-70 percent vaccination threshold. Assuming that all goes well with the vaccine and it performs as intended. For a long time vast portions of the population will continue to be at risk.
