Moderna starts dosing patients in mid-stage coronavirus vaccine study

Moderna Inc said on Friday it had started dosing patients in a mid-stage study with its experimental coronavirus vaccine and eventually plans to enroll 600 patients for the trial.

There are currently no approved treatments or vaccines to treat COVID-19, the respiratory disease caused by the new coronavirus, and experts predict a safe and effective vaccine could take 12 to 18 months from the start of development.
