Yes, that is my understanding. The CDC proclamation is just guidance. I have heard figures in states that say things like 70% fully vaccinated in Maryland, 65 in WV, etc...before the masks can come off. And then the stores can make their own rules Re: Giant/Martins can say Masks required even if the Gov does not. So it may be a bit of a mixed bag.
Some of your stats may support vaccines like you mentioned. Not sure what their rates are though.
