Excuse me, president who?
You know this but someone needs to say it for the befefit of any cognitively-impaired in the audience:
Trump prioritized resources for the development of a vaccine, which has proven to be the most effective way of reducing loss of life from disease.
In no way does that shift any responsibility to him for the safety or efficacy of the specific vaccines that were developed. That is the sole reason the FDA was created and why it exists.
