New Study Adds to Growing Body of Evidence Suggesting Mask Mandates Are Ineffective

A new study published this month revealed that COVID-19 mask mandates in schools have little to no effect.

“Our findings contribute to a growing body of literature which suggests school-based mask mandates have limited to no impact on the case rates of COVID-19 among K-12 students,” researchers at the University of Southern California and the University of California–Davis said in a preprint study published on Research Square.

Researchers evaluated two school districts in Fargo, North Dakota, in which one had a mask mandate and the other did not during the 2021–2022 academic year.

“We observed no significant difference between student case rates while the districts had differing masking policies nor while they had the same mask policies,” they noted, adding that the “impact of school-based mask mandates on COVID-19 transmission in children is not fully established” amid mandates nationwide.

A number of other studies have found no link between mask mandates and a drop in COVID-19 cases.

In one study published in May, researchers found that COVID-19 mask and vaccine rules implemented by Cornell University had limited impact against the transmission of Omicron in late 2021 and 2022.

“Cornell’s experience shows that traditional public health interventions were not a match for Omicron. While vaccination protected against severe illness, it was not sufficient to prevent rapid spread, even when combined with other public health measures including widespread surveillance testing,” the paper said.

And researchers in Spain found that mask mandates for children in Spain weren’t linked to a lower rate of COVID-19 cases or transmission.

In an evaluation of schoolchildren, kids aged 6 and older in Catalonia were required to wear masks once school reopened during the COVID-19 pandemic, the researchers said.

Researchers compared the incidence of COVID-19 in older children to younger children to try to determine whether the mandates had been effective in the aim of reducing transmission of the CCP (Chinese Communist Party) virus, which causes COVID-19, in schools.

Their study identified a much lower case rate in preschool, where there were no mandates when compared to older groups who were required to wear masks. Five-year-olds, for instance, had an incidence of 3.1 percent, while 6-year-olds had an incidence of 3.5 percent.

Researchers in Toronto, Canada, and California replicated a 2021 Centers for Disease Control and Prevention study of counties in Arizona, published in The Lancet in May, that expanded the number of data points and extended the time period. They discovered that cases quickly declined in the weeks after the CDC cut off its study and decreased more quickly in the counties that didn’t have mask mandates.

“School districts that choose to mandate masks are likely to be systematically different from those that do not in multiple, often unobserved, ways. We failed to establish a relationship between school masking and pediatric cases using the same methods but a larger, more nationally diverse population over a longer interval,” the researchers said.

“It was known long before COVID-19 that face masks don’t do anything,” Former Pfizer VP Michael Yeadon, a toxicologist and allergy research specialist, told The Epoch Times in May.  “Many don’t know that blue medical masks aren’t filters. Your inspired and expired air moves in and out between the mask [and] your face. They are splashguards, that’s all.”
