Even in countries where a second wave is happening, it’s a wave of infection only, not deaths. There is not reason to be scared of a disease that don’t kill. International travel restrictions should be lifted. We don’t need to wait for a vaccine that might be more a dangerous than to virus it’s supposed to fight. Current practices in East-Asia have shown to be enough to handle the thing.
This is not universally true. In parts of California there was a jump in death rate reasonably close to a partial reopening. And has very slowly been trending downwards since they re-closed everything.
My point is insofar as one would/should fear death, they would/should fear a decent probability long term nonfatal consequences to some degree. Incomplete information doesn't obviate that.
