I should have been clearer.
What is the main impact right now on keeping hopsitalisations/deaths low? It's the vaccines.
The evidence that masks aren't really that important is surely that right now, in this 'third wave' of cases, we're hitting similar case numbers as we were last autumn - back when masks were compulsory too. Had they had so much impact, we would surely have seen a bit more of a dent in the numbers.
Now, obviously, on a crowded train or public place or shop, I wear a mask and I'm happy to do it and honestly, like I've said, I'm surprised that they're not keeping them as mandatory.
But if the data really, really did suggest that they were so vital, I don't think they'd be dropping them...
They're an extra safety precaution, but social distancing (as in the most literal sense when we had to do that) was much more effective than masks, and the vaccination is much more effective than that because it allows stuff to open again.
I can't wait to go to a gig, hopefully the one I've got booked in August goes ahead. I'm sure everyone can't wait to be back in Goodison in a month too.
Obviously if you run a search there'll be plenty of articles either way on the subject. But just going off the actual numbers, I really can't see masks have been as effective in saving lives as the poster seemed to suggest.
