No. That only explains why Trump pushed for the creation of the vaccine. It does not explain why he shilled for it and acted as its most enthusiastic cheerleader. He is very good with words and he had great speech writers. He could easily have spoken in such a way that everyone could have read whatever they wanted into his words. He didn't. He actively encouraged people to go jab themselves, even long after he needed to. He left no room for interpretation and even continued when people started boo'ing him at his rallies. He definitely did not act as someone stuck between a rock and a hard place and doing this out of necessity. He went full on rock.

No. This question definitely has NOT been answered.
