I don’t see how anything like normal life returns without a vaccine. Zeke Emmanuel has said this on TV, and I believe he is correct. Because there is no herd immunity, fifteen cases on the way down is pretty much the same as fifteen cases on the way up. Set someone loose in a crowd with an R0 2.4 bug, and soon everyone who is not immune is sick. The thing must burn itself out virtually worldwide (unlikely), or we need to develop herd immunity by vaccination. (Social distancing prevents herd immunity.)

On vaccine development, I am curious as to how the annual flu vaccine is ready every year. The strains are different, so the vaccine must be different. But we don’t test each vaccine for a year, because we can’t. If a platform is deemed safe, the seasonal variant is assumed safe. Should we not be trying to do the same thing with coronavirus? Is that technologically beyond our capability?
