A few studies recently promoted by MSM suggest that some "masks" (medically approved surgical masks) only reduce transmission of SARS-CoV-2 by 30 to 50%. The same studies also concluded that cloth masks were less effective than that. Note that these studies required "social distancing" in order to achieve the 30% to 50% mask-wearing protection.

For example:
