It's a Quantum superposition. If you are trained, and use your mask correctly, it provides some protection. This represents about 15% of the general public that wear masks. I firmly believe a study would show that the rest make it worse by overly touching their face, and believing that the mask is a bulletproof vest. My mother, the nurse, thinks that is incredibly crazy.
Some protection means nothing because it doesn’t take much to get infected in the first place. There are lots of studies about respiratory viruses and minimum infective dose rate.

I agree. Masks of the proper quality, used by trained medical professionals, offer some protection.
Heart-lung machines work, but I would not trust someone to be given one and use it without instruction.
