A report published by the UK Health Security Agency (UKHSA) found that “no evidence could be presented” to prove medical-grade face masks protected vulnerable people from COVID.
The study investigated whether so-called high quality masks such as N95, KN95 and FFP2 coverings helped protect vulnerable people in the community from catching the virus.
“The review did not identify any studies for inclusion, and so could provide no evidence to answer the research question,” the authors concluded. “No studies matching the inclusion criteria were found, so no evidence could be presented.”
Well, there goes the narrative.
Prof Carl Heneghan, professor of evidence-based medicine at the University of Oxford, noted that it was a “significant failing” that there were virtually no high quality trials showing that face masks were effective at preventing infection.
“I do not understand why there’s been a lack of will to do high-quality trials in this area,” he told the Telegraph. “We have completely failed to address this issue and I actually consider that to be an issue that the [Covid] inquiry needs to look at.”
