The goal of the flattening of the curve by social distancing and quarantining was to prevent the medical facilities and resources from being overrun. It was meant to buy time, build hospital capacity and stock resources. There is no vaccine, and waiting for one is not an option. It takes a year and a half to develop a vaccine. By that time, 50 million people would be unemployed and there would be death and devastation everywhere. They are experimenting with treatments to reduce the death rate, but they still don't have a cure. The only option is to start moving forward by taking safety precautions and dealing with flare ups as they occur until they hit on a medication treatment or a vaccine.
