Moderna CEO: vaccine should protect for 'couple of years'

The U.S. biotech company, which stunned the world last year by coming up with a vaccine against the disease caused by the new coronavirus in just a few weeks, received approval for its shot from the European Commission on Wednesday (January 6).

Given vaccines development and pharmacovigilance usually requires years, the protection duration of COVID-19 shots is a lingering question for scientists and regulators.

"The nightmare scenario that was described in the media in the spring with a vaccine only working a month or two is, I think, out of the window," Moderna CEO Stephane Bancel said at an event organized by financial services group Oddo BHF.
