Russia released the vaccine to the public directly without doing a phase 3 trial. That's the reason they could widely distribute the vaccine so early. China, on the other hand, are conducting proper phase 3 trails (randomized, double blind) for 3 vaccines currently, the most in the world. That's the reason why many think China will be the first one actually to have a clinically proven vaccine.
Indeed and considering that the US as far as I know doesn't have a phase three that is conducted around the world as of now, it stands to say that the US isn't going to be the place they people around the world will place trust in in regards to medicine anymore. In the past, the world may have looked at the USA as a pioneer in medication but those days are long gone. I wonder how the US must feel knowing the Trump has exposed the nation as becoming more and more irrelevant if only relevant due to there weapons of mass destruction.
