The world’s biggest COVID-19 vaccine study is now underway 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.

There’s still no guarantee that the experimental vaccine, developed by the National Institutes of Health and Moderna Inc., will really protect against infection.

Volunteers won’t know if they’re getting the real shot or a placebo. 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. Dr. Stephen Hahn, the Food and Drug Administration commissioner, said Monday that testing is taking place at 89 sites across the country. At an event with Vice President Pence in Miami, he said that over 100 vaccines around the world are in different stages, and he expects at least two more to be in phase 2 in the coming weeks.

Several other vaccines made by China and by Britain’s Oxford University began smaller final-stage tests in Brazil and other hard-hit countries earlier this month.

But the U.S. requires its own tests of any vaccine that might be used in the country and has set a high bar: Every month through fall, the government-funded COVID-19 Prevention Network will roll out a new study of a leading candidate — each one with 30,000 newly recruited volunteers.

The massive studies aren’t just to test if the shots work. They’re also needed to check each potential vaccine’s safety. Following the same study rules will let scientists eventually compare all the shots.

Next up in August, the final U.S. study of the Oxford shot begins, followed by plans to test a candidate from Johnson & Johnson in September and Novavax in October, if all goes according to schedule. Pfizer Inc. plans its own 30,000-person study this summer.

That’s a stunning number of people needed to roll up their sleeves for science. But in recent weeks, more than 150,000 Americans filled out an online registry signaling interest, said Dr. Larry Corey, a virologist with the Fred Hutchinson Cancer Research Institute in Seattle, who helps oversee the study sites.

“These trials need to be multigenerational, they need to be multiethnic, they need to reflect the diversity of the United States population,” Corey told a vaccine meeting last week. He stressed that it’s especially important to ensure enough Black and Hispanic participants as those populations are hard-hit by COVID-19.

A new poll by CBS News suggests that if a vaccine became available this year, many Americans could approach it cautiously, and 20% say they would “never” get the vaccine. Only 30% say they would get one “as soon as possible.” Many more, half of the country, say they would consider it, but would first “wait to see” what happened to others.
