The Mask Mandates Did Nothing. Will Any Lessons Be Learned?
The most rigorous and comprehensive analysis of scientific studies conducted on the efficacy of masks for reducing the spread of respiratory illnesses — including Covid-19 — was published late last month. Its conclusions, said Tom Jefferson, the Oxford epidemiologist who is its lead author, were unambiguous.
“There is just no evidence that they” — masks — “make any difference,” he told the journalist Maryanne Demasi. “Full stop.”
But, wait, hold on. What about N-95 masks, as opposed to lower-quality surgical or cloth masks?
“Makes no difference — none of it,” said Jefferson.
What about the studies that initially persuaded policymakers to impose mask mandates?
“They were convinced by non-randomized studies, flawed observational studies.”
