The US is not the only country to produce a vaccine and Trump is not the reason it produced a vaccine. That Pfizer vaccine we are talking about? Developed by the Krauts in a couple of hours in January 2020.People can say what they want about Trump's handling of covid but America is the only country who had a coherent plan to develop and produce a covid vaccine.
The US was always going to be at the forefront of vaccine development and production, whether it was Trump, Biden, or your neighbor's Golden Retriever sitting in the Oval Office.
And the Russians have the best vaccine.
