A top FDA official says he'll resign if the Trump administration pushes a coronavirus vaccine through before it's ready.
For many, a vaccine is the benchmark for when life can go back to normal. The administration is hoping to push one out before the end of this year.
But — for context — the fastest vaccine ever created was the mumps vaccine, and that took four years.
There's concern the president will pressure the FDA to authorize a vaccine before the election. FDA official Peter Marks told Reuters that approving anything unsafe crosses a line for him and he'd have to step down.
