90% of New York City adults are already vaccinated. Yet new cases in the city have tripled in the past month.
Eventually you have to admit that the vaccines failed... and the boosters aren't going to help, either. It doesn't matter how many antibodies you generate; the antibodies work against Delta, but it still spreads because Delta breeds in the nose, avoiding the antibodies altogether. So reformulating the vaccine won't work.
And because it produces so many more copies of the virus in the nose, it overwhelms flimsy paper masks, especially if the wearer has a beard and ruins the seal. So a mask mandate isn't going to do squat, either.
But public health is going to stay locked into the same failed schemes, instead of addressing why they failed.
