Markets dipped, Trump's numbers dipped. Fauci was praised for publicly his boss claim that it would be out by December. Fauci lied.
If you don't know something, you say, "i don't know". But in Fauci's position, to categorically state that the vaccine will not be available unitl Jan 2021 IF NOT LATER when that statement proves to not to be true is a flat out lie. Fauci could have said that "It's possible, but not likely that what Trump said about the vaccine coming out by Dec is true". But he did not. He had a specific intent to undermine the president before the election. And the president proved to be correct. Just another lying bureacrat who Trump should not have retained.
