The large-scale tests in the United States this summer may provide another opportunity. On Monday, Moderna announced partial data of its first-phase trial, saying its vaccine candidate had proven safe and that it had provoked an immune response in 8 of 45 people. It is also working on an accelerated timetable with partners at the National Institute of Allergy and Infectious Diseases and the Swiss company Lonza. Moderna received approval to move to a second phase involving 600 people and said it would also begin a third stage in July with thousands of healthy people.
