WHO knows?
Funny... No they don’t.
We didn’t have a vaccine for the Spanish flu, the Asian flu or the Hong Kong flu... We don’t need a vaccine for this one either. It will peter out like all the other previous flu viruses we have endured and we endured all the previous viruses without destroying our economy... Next virus outbreak... Shut down international travel and wear a mask... Keep everything open and practice social distancing as much as possible... Lessons learned.
