His administration deserves at least some of the credit. Trump has always been pro-vaccine, hasn't he? Maybe I'm misremembering this...
He's been pro-vaccine since the measles outbreak a few years ago at least but prior to that he had made comments about there possibly being a link between vaccines and autism.
Personally I won't be getting this vaccine since I had a bad reaction to a flu vaccine a few years ago I decided that it was better if I avoided future vaccines.
