US President Donald Trump said Tuesday that a coronavirus vaccine may be available within a month -- an acceleration of even his own surprisingly optimistic predictions -- but added that the pandemic could go away by itself.
"We're very close to having a vaccine," he told a town hall question-and-answer session with voters in Pennsylvania.
"We're within weeks of getting it you know -- could be three weeks, four weeks," he said.
Only hours earlier on Tuesday morning, Trump had said a vaccine could come in "four weeks, it could be eight weeks."
