This needs to be pointed out:
CDC Dir. Rochelle Walensky defends new mask guidance for vaccinated Americans, telling @MarthaRaddatz: "We now have science that has
really just evolved even in the last two weeks that demonstrates that these vaccines are safe, they are effective."
So is she saying they had no idea what the risks/effectiveness would be for people who got the vax prior to May? Is she talking out of her ass, or did the CDC push a vaccine that they were unsure of. Either one is deeply concerning.
