The back and forth on masks and such has been based on:
A- it's a new virus that we are learning about and adjusting previous assumptions to follow the science
B- new strains are behaving differently, so back to A
C- many people don't want to get vaccinated and don't wear masks
D- a couple snafus in communication
E- but mostly A
The media wasn't happy with a rushed approval that Trump wanted before the election.... for similar unproven safety reasons you are claiming, ironically. Except today we are a year and 100's of millions of vaccinated people down the road.
Were you happy with Trump wanting to rush the vaccine last year?
