we are well on the way to a vaccine -which also produces herd immunity -
With normal vaccines, 80% of vaccines that get large-scale clinical trial completely fail. Best guess is Covid-19 will be worse. The immune reaction to Covid-19 is weak, so normal vaccines are failing. The novel proposed vaccines have much higher failure rates.
Then there is the issue of manufacturing the vaccines. trump has placed his hopes that everything will work out well, and so has "saved money" by not trying to overproduce vaccines. Given that the odds are extremely against us, we should be "wasting" money by building too much manufacturing. That way some of it will probably work.
