action to stem a wave of omicron infection, but what can be done? what action specifically are you calling for? well, i think there are a number of things that can be done and need to be done. first of all, obviously, pulling out all stops on vaccinations, especially trying to get folks who have not yet been vaccinated at least get a primary series. getting boosters into folks who have not yet been boosted. but we need to do more to step up non-pharmaceutical interventions. those things that we had and we effectively used before we had access to vaccines. that s things like wearing face masks indoors, and in the u.s., certainly, mandatory face mask ordinances in a number of state and local areas had a significant impact. also, limiting large indoor gatherings and attempting to contain and control spread in congregant environments, such as school.
