The United States plans a massive testing effort involving more than 100,000 volunteers and a half dozen or so of the most promising vaccine candidates in an effort to deliver a safe and effective one by the end of 2020, scientists leading the program told Reuters.

Between 100,000 and 150,000 people may be enrolled in the studies, said Dr. Larry Corey, a vaccine expert at Fred Hutchinson Cancer Center in Seattle, who is helping design the trials. Human testing begins with a small safety trial in healthy volunteers, followed by a larger study to find the right dose and get an early read on efficacy. The final stage consists of large-scale testing in thousands of people. Only then would a vaccine developer commit to manufacturing millions of doses.
The U.S. government has committed billions of dollars to help manufacturers produce doses of vaccines that may never prove successful.To get the quickest answer, vaccines will be tested in healthcare workers and communities where the virus is still spreading to show whether they reduced new cases of COVID-19.
