Earlier quoted context omitted.
Remember, the game plan that virologists came up with for COVID acknowledged that most people will get it eventually. The point of the lockdowns was not to eliminate spread, which is impossible, but to not overwhelm the system.
The plan is/was also to understand it, find effective protocols for managing it, etc. (And we also have pretty good chances of coming up with a vaccine in about 1 year.) It's not "just the same amount of death, but slower, so the crematoriums don't get overwhelmed".
This is just wishful thinking. We've never had effective vaccines for this sort of virus. (The yearly flu vaccine is like 30% effective.) Sure lots of research groups are working on vaccines, but many of them are academics who have no particular duty to work on research likely to have an immediate payoff. The researchers who do have such a duty, i.e. those who work for private drug firms, are mostly developing treatments like the antiviral remdesivir. Effective treatments of various sorts are closer than any vaccine, for COVID-19. IMHO, the most likely eventual winner will be a scaled-up version of the convalescent plasma therapy, which unlike the current version will be able to produce effective antibodies without drawing blood from humans.
