Massive Peer-reviewed Mask Study Shows ‘Little to No Difference’ in Preventing COVID
A massive international research collaboration that analyzed several dozen rigorous studies focusing on “physical interventions” against COVID-19 and influenza found that they provide little to no protection against infection or illness rates.
The study, published in the peer-reviewed Cochrane Database of Systematic Reviews, is the strongest science to date refuting the basis for mask mandates worldwide.

And of course, the CDC still recommends masking in areas with “high” rates of transmission (fewer than 4% of US counties, as Just the News notes), along with indoor masking in areas with “medium” rates of transmission (27%).
Masks are still required in educational institutions in Democratic strongholds such as New York, New Jersey, Massachusetts, Pennsylvania, Washington and California, according to the Daily Mail. Boston Public Schools denied its “temporary masking protocol” in early January was a “mandate,” following a public letter against the policy by student Enrique Abud Evereteze.

According to the Cochrane study, which included the work of researchers at institutions in the U.K., Canada, Australia, Italy and Saudi Arabia, a total of 78 studies were analyzed. Most recent additions to the meta-analysis were 11 new randomized controlled trials.
As unlisted study author Carl Heneghan – who directs the Centre for Evidence-Based Medicine at the University of Oxford noted on Twitter: “Wearing masks in the community probably makes little or no difference to the outcome of influenza‐like illness (ILI)/COVID‐19 like illness compared to not wearing masks.”
We included 11 new RCTs and cluster‐RCTs (610,872 participants) in this update, bringing the total number of RCTs to 78.— Carl Heneghan (@carlheneghan) January 30, 2023
Wearing masks in the community probably makes little or no difference to the outcome of laboratory‐confirmed influenza/SARS‐CoV‐2 compared to not wearing masks (RR 1.01, 95% CI 0.72 to 1.42; 6 trials, 13,919 participants; moderate‐certainty evidence).— Carl Heneghan (@carlheneghan) January 30, 2023
Bottom line, mask wearing “probably makes little to no difference,” when it comes to influenza-like or COVID-like illnesses, regardless of type of mask used.
2/ LARGE Cochrane Rev (just published 1/30/23) of RCT data ALSO CONFIRMS NO BENEFIT of N95 masks vs. med/surg masks, in either community (n~8K) or HCW (n~8K) settings for prevention of flu-like illness or lab confirmed flu https://t.co/N4TkgI4uUR pic.twitter.com/0DCdYAPo7x— Andrew Bostom, MD, MS (@andrewbostom) January 31, 2023
