You keep quoting that 97% vs 3% but I don't think you understand what it means.

It's the end result of using a cloth mask for 4 weeks all day, and counting all infections. This is important because some viruses are transmitted through aerosol and there the mask is useless.

It's like if I did a study to test the effectiveness of body armor. I shoot 3 full mags of AK-47 on very courageous subjects, and after the 90 rounds I see that only 3% survived. That's my study. Then you come along and conclude that "body armor has only 3% effectiveness, and therefore it's useless to wear it".

That's what you're doing.

You don't wear a body armor thinking that it'll save you from 100 AKs, you wear it hoping that it might help your chances against a stray bullet.

Similarly, you don't wear a cloth mask to enter a ward of 100 covid patients all coughing at you. It would be almost useless in that case. But it can help if you're in a store where one of the customer is infected and might breathe in your general vicinity.
