I think they knew it was rather unnecessary to wear a mask after being fully vaccinated, but waited for a lull in vaccinating to give that guidance. It gives people a potential motivation to go get vaccinated. Call me dumb, but they should have just given people stimulus checks to go get it. Vaccinations jumped 25%+ in Ohio after they started their little lotto game. Can you imagine if you were guaranteed $1K in your bank account if you went and got it? I think I recall some politicians floating the concept, but it didn't gain traction. I know I know, people should just get it for free, but that just is not reality.
