KEY POINTS
  • The Trump administration's coronavirus vaccine program Operation Warp Speed expects to have up to 100 million doses by the end of the year, Health and Human Services Secretary Alex Azar said.
  • Azar said the U.S. is currently manufacturing doses for all six potential vaccines backed by the U.S. government across more than 23 manufacturing facilities.
  • U.S. health officials have been accelerating the development of vaccine candidates even though doing so could be for naught if the vaccine ends up not being effective or safe.

Health and Human Services Secretary Alex Azar said Thursday the U.S. could have enough Covid-19 vaccine doses for every American as early as March, a more optimistic estimate than President Donald Trump has publicly said.

The Trump administration's coronavirus vaccine program Operation Warp Speed expects to have up to 100 million doses by the end of the year, Azar said during a keynote speech at the Goldman Sachs Healthcare virtual event on the coronavirus. That's "enough to cover especially vulnerable populations," he said.
