The European Medicines Agency (EMA) is due to hold a meeting today, two days ahead of schedule, that could decide to recommend approving Moderna's Covid-19 vaccine, a spokesperson said.
The EMA's human medicines committee (CHMP) had previously been scheduled to meet on Wednesday to discuss the potential approval of a second Covid-19 vaccine for use in Europe.
The agency has set a January 12th deadline for whether to recommend Moderna's vaccine having already given approval to the Pfizer BioNTech vaccine on December 21st.
"In the event that the CHMP reaches an opinion at today’s meeting, we would send out a press release as soon as possible after the meeting," it said in a statement.
A CHMP meeting scheduled for Wednesday was still planned "in case the committee does not reach a decision today," it added.
The Moderna vaccine has already received approval for use in the US.
