EXCERPT:
RISCH: "No, there’s no adequate evidence to show that masks work for what’s called source control to prevent the spread of Covid to other people. And in fact, one of the reports said there's nothing new in the last week. That's not even true because the study from Spain came out in the last week or so showing that 5-year-olds who are not masked against 6-year-olds who are masked, the whole year had almost identical cases of Covid and secondary spread. It shows that masks are essentially useless."
