WASHINGTON (Reuters) - U.S. President Donald Trump said on Thursday it was possible the United States would have a coronavirus vaccine before the Nov. 3 election, a more optimistic forecast than timing put forth by his own White House health experts.

Asked on the Geraldo Rivera radio program when a vaccine might be ready, Trump said, "Sooner than the end of the year, could be much sooner."
