It is not going to stop... new variants, booster shots, masks, lock downs, tests for everyone everyday. Get over it. It's like airport security, once setup, the system is not going away and soon nobody will remember how life used to look like before all of it happened.
It actually differs from airport security in one crucial way: vaccination actually works, and it will continue to work. Airport security measures, at least the ones commonly discussed, the ones that spring up after 9/11, have zero effect these days, since the threats they were supposedly intended to combat were solved the moment cockpit doors were required to remain locked at all times. Vaccines work, boosters work,…
Before you flame me - I don't think they are to be used constantly, or all at the same time. They are all valuable tools to reducing the pain, suffering, and lost productivity of respiratory illnesses. I'd like to see universal masking in schools during flu season, for example. Limited group of people, limited time, but would happen every year. Maybe there's a trigger for a "bad" flu season.
It's insane to say we should not use things that work because they might be useful in the future. We just need to be smart about how we use all these interventions, WHICH WE ABSOLUTELY ARE.
