The most quality and powerful scientific study on masks which concluded no difference between those who wore masks and a control group who did not was not allowed to be published by any of the establishment medical journals. The study concluded that the “recommendation to wear surgical masks to supplement other public health measures did not reduce the SARS-CoV-2 infection rate among wearers by more than 50% in a community with modest infection rates, some degree of social distancing, and uncommon general mask use. The data were compatible with lesser degrees of self-protection.” Not only did it not reduce it by 50% as noted in the conclusion, the between-group difference was -0.3 percentage point – less than half of 1%, or essentially wearing a mask made NO difference in ones ability to test positive for a covid test. There were approximately 3000 in both the test group and the control group, a total of about 6000 participants and almost 5000 were able to complete the study successfully.
