Unravelling the Role of the Mandatory Use of Face Covering Masks for the Control of SARS-CoV-2 in Schools: A Quasi-Experimental Study Nested in Population-Based Cohort in Catalonia (Spain), Coma, 2022
I have updated this paper today with the editor of Brownstone to include the new Catalonia Spain retrospective study on face masks in children, now totally 168 pieces of evidence on ineffectiveness of COVID face masks (blue surgical masks and white cloth masks/man made face coverings). To date, the evidence has been stable and clear that masks do not work to control the virus and they can be harmful and especially to children.
Updated op-ed paper of over 150 studies/pieces of evidence:

“FCM mandates in schools were not associated with lower SARS-CoV-2 incidence or transmission, suggesting that this intervention was not effective.”
