Clinical trial for COVID-19 vaccine to begin in US
(AP) -- A clinical trial evaluating a vaccine designed to protect against the new coronavirus will begin Monday.
A government official says the first participant in the trial will receive the experimental vaccine that day.
The National Institutes of Health is funding the trial that is taking place at a Kaiser Permanente research facility in Washington State.
Public health officials say it will take a year to 18 months to fully validate any potential vaccine.
