Original Note:
The BBC article is misleading. Randomised trials for mask types are needed for "high quality evidence", but impossible, because participants know what type of mask they're wearing. A real-world study showed that switching to FFP3 masks reduced Covid infections by up to 100%. https://www.cam.ac.uk/research/news/upgrading-ppe-for-staff-working-on-covid-19-wards-cut-hospital-acquired-infections-dramatically
