It's not "Trump's vaccine". He made a promise to the people that there would be a vaccine before the end of his first term which he fulfilled. The reason nobody wants to take it is due to the fact that money grubbing corps with legal protection in case of side effects made it and is technically still experimental. The same as him backing up Fauxi. He was told these people can be trusted and went along with it. Trump is not to blame or associated with the vaccine other than removing the red tape to get it released fast.
