The United States is planning to test “half a dozen or so” of the most promising potential coronavirus vaccines with 100,000 to 150,000 volunteers, Reuters reported on Friday, citing scientists familiar with the matter.

The Oxford vaccine may be tested side by side with Moderna’s vaccine starting in July, US health officials told Reuters. “Vaccines from J&J, Sanofi and Merck may be added this summer as they complete phase I safety studies.”
