Agreed, but mask mandidates would have ended this in the US. Masks still work, even against Omnicron. We are idiots.
Some masks do, sure. But the masks most people are wearing aren't effective against Omicron.
But again, you'll NEVER get 100% compliance on anything, which is why the 'two weeks' has become two years. Acting as if all humans will always comply (or that all will even know to) is unrealistic. We were never going to beat this, not with masks, not with these vaccines.
We may end up with a vaccine that completely huts down the virus, but masks aren't alone were never going to solve this.
At this point, I'm happy to be vaccinated, I wish everyone was - but a mandate isn't stopping anything.
