Physical interventions to interrupt or reduce the spread of respiratory viruses - Jefferson, T - 2023 | Cochrane Library

The pooled results of RCTs did not show a clear reduction in respiratory viral infection with the use of medical/surgical masks.

Opinion | The Mask Mandates Did Nothing. Will Any Lessons Be Learned? - The New York Times

But when it comes to the population-level benefits of masking, the verdict is in: Mask mandates were a bust. Those skeptics who were furiously mocked as cranks and occasionally censored as “misinformers” for opposing mandates were right. The mainstream experts and pundits who supported mandates were wrong. In a better world, it would behoove the latter group to acknowledge their error, along with its considerable physical, psychological, pedagogical and political costs.

How Some Parents Changed Their Politics in the Pandemic - The New York Times

In interviews, 27 parents who called themselves anti-vaccine and anti-mask voters described strikingly similar paths to their new views. They said they had experienced alarm about their children during pandemic quarantines. They pushed to reopen schools and craved normalcy. They became angry, blaming lawmakers for the disruption to their children’s lives. Many congregated in Facebook groups that initially focused on advocating in-person schooling. Those groups soon latched onto other issues, such as anti-mask and anti-vaccine messaging. While some parents left the online groups when schools reopened, others took more extreme positions over time, burrowing into private anti-vaccine channels on messaging apps like WhatsApp and Telegram. Eventually, some began questioning vaccines for measles and other diseases, where inoculations have long been proven effective. Activists who oppose all vaccines further enticed them by joining online parent groups and posting inaccurate medical studies and falsehoods.
