The world’s biggest COVID-19 vaccine study has begun with the first of 30,000 planned volunteers helping to test shots created by the U.S. government -- one of several candidates in the final stretch of the global vaccine race.

The study began Monday. Volunteers won’t know if they’re getting the real shot or a dummy version.

After two doses, scientists will closely track which group experiences more infections as they go about their daily routines, especially in areas where the virus still is spreading unchecked.
