How do we avoid a second wave of coronavirus until we get a vaccine?
Not sure it's possible unless people remain imprisoned at home for several months (the Wuhan model), or they isolate and wear hazardous equipment when leaving home (but there are equipment shortages).
Even going to the store means the virus will remain active, ready to reemerge.
Maybe until then we just live mostly isolated lives, avoid overwhelming health services, build community immunity and hope the thing ends soon.
Earliest date for a vaccine that I am aware of is September. 6 months of isolation would be VERY boring indeed.
