National Institute of Allergy
and Infectious Diseases Director Anthony Fauci said COVID-19 vaccine candidates
will start moving into late-stage clinical trials by the end of July,
continuing through the summer and into fall. "We may be able to at least
know whether we are dealing with a safe and effective vaccine by the early
winter, late winter, beginning of 2021," Fauci said.
