29 September 2020 - The FDA, under commissioner Stephen Hahn, is in the middle of one of the most highly charged debates in US politics.
The head of the US FDA has risked sparking a fresh conflict with Donald Trump over the timing of a coronavirus vaccine, after insisting his scientists would stick to a set of guidelines that the US president has threatened to overrule.
Stephen Hahn, FDA commissioner, said on Tuesday his officials would assess any vaccine application against a set of criteria that experts say make it all but impossible that one will be available before November’s election.
