German pharmaceutical company BioNTech and its U.S. partner Pfizer say they have submitted an application for conditional approval of their coronavirus vaccine with the European Medicines Agency.

The two companies said Tuesday that the submission, which occurred Monday, completes the rolling review process they initiated with the agency on Oct. 6.

The move comes a day after rival Moderna said it was asking U.S. and European regulators to allow emergency use of its COVID-19 vaccine.

BioNTech said that if the vaccine, currently named BNT162b2, is approved, its use in Europe could begin before the end of 2020.
