My personal approach has been to try to get dancing in now as much as possible, since the risk level has looked like it's as low as it's going to be for the foreseeable future. Of course, I'm in the US, and have lost faith in the reasonableness of my fellow countrypeople.Probably. It's a rolling risk based on current observation. 16 months ago vaccines were hoped for but were expected to take a year at least to develop. They've now arrived, but not as effective as hoped (although that was hope over reality).
