It won't happen like that.
It's like curing cancer. We won't ever have this giant headline that cancer is cured. It's more complicated. There will be trials that will be followed closely, good results and bad results. Even at this point a vaccine isn't a huge deal as it's only 2% fatal. The bigger issue is understanding contagious periods and getting (at risk) people to cooperate and behave. The concern is legit, but I agree it's likely also transient. The equity drop is a good housecleaning, but we're getting into an area where there will be material economic slowing from quarantining and closing so much stuff in more and more areas.
Cancer is quite different in almost every way. Coronavirus is a virus after all and vaccinating for a virus has been done, for a cancer though...


Still profitable though.
