Even if vaccines are available there may be many who just don't take them, so if that happens, you're back where you started. I hope that doesn't happen though.
C&CR going virtual may not be a bad idea, but I haven't heard anything about that possibility. But then again, I'm not in the loop so who knows? If that were to come to pass, I wonder how sightreading would be handled? Would they email a score and parts to the school after a band did their concert performance? And for concert and sightreading how would any technical issues such as freezes or power outages be handled?
