Funny, CDC said the same thing back in 2010..........
Somewhere early on in the Covid last year, there was a report (from the Surgeon General before he got on board?) that stated the CDC had conducted something like 10 statistically significant double blind trials with masks since the 1960's. Exactly zero of the 10 showed any statistical reduction in the transmission of cold and flu like viruses (eg: Covid). That report / comment was quickly covered over in the rush to gain control of the narrative.
They used the charade to crash the strongest economy ever, and to get Trump out of office. They can allow some modicum of truth to start trickling out again now that Uncle Joe is in control...
