Biden's former COVID adviser tries to discredit randomized controlled trial that found no statistically significant real-world performance difference between surgical masks, N95s. Fauci reportedly can't cite any evidence masks work in deposition.
The science is retardedly easy, how many microns is a virus and how many microns is a particular mask rated for? IE can a chain link fence prevent me from pissing through it.
