Optimism shmoptism! We need the rationers, the confiscators, the controllers, and the military to wage WAR on this non-plague. World War V is a week away.
I am betting on Sunshine. It is effective against all seasonal flu and colds. Lacking sufficient sun exposure as in winter, vitamin D3 supplements substitute nicely. My whole family and i have not had any respiratory viruses since we started taking the supplements 14 years ago and we do not get flu shots. Ever. I may be wrong on this one but it is, at least, prophylactic that I can use right now and is better than hermetically sealing my house and hoping the gummint will save me with a WuHanFlu shot.
