The fully vaccinated population of the USA is around 50%. Canada is now around 60%.

As of 16 July, 48.45% of Canadians are fully vaccinated against Covid-19, compared with 48.05% of Americans.
Canada is flying toward 80%+ because we still have a huge chunk waiting the 4 weeks for the second vaccine. USA has had vaccines for months longer so they are barely moving in that regard and will end up in the 55-60% range for now.
I have no idea why you think there is a >0% chance Fauci would be there if Trump won again. He was barely there at the end of his first term. If Trump won again he would fire all the "grown ups in the room" instantly and replace them with people that would do his bidding. Why would he care, he can't lose another election at that point, which was probably the one thing holding him back in his first term.
If you think derps are derping now, just imagine if Trump won and he and his quack doctor and staff were out there doing constant freedom rallies. He probably would not even bother suggesting people should take the vaccine.
