EMA has received an application for conditional marketing authorisation (CMA) for a COVID-19 mRNA vaccine by Moderna Biotech Spain, S.L. (a subsidiary of Moderna, Inc.). The assessment of the vaccine known as Moderna Covid-19 vaccine (also referred to as mRNA1273) will proceed under an accelerated timeline. An opinion on the marketing authorisation could be issued within weeks, depending on whether the data submitted are sufficiently robust and complete to show the quality, safety and effectiveness of the vaccine.

Such a short timeframe is only possible because EMA has already reviewed some data on the vaccine during a rolling review. During this phase, EMA assessed data from laboratory studies and also started assessing data on immunogenicity (how well the vaccine triggers a response against the virus) and safety from an early study.

EMA will now assess the data submitted as part of the formal application for conditional marketing authorisation. The Agency and its scientific committees will continue working on the assessment over the Christmas period. If the data submitted are robust enough to conclude on the quality, safety and effectiveness of the vaccine, EMA’s scientific committee for human medicines (CHMP) will conclude its assessment during an extraordinary meeting scheduled for 12 January at the latest. These timelines are based on the type of data assessed so far in the context of the rolling review and may be subject to change as evaluation proceeds. EMA will communicate on the outcome of its assessment accordingly.

During the review, and throughout the pandemic, EMA and its scientific committees are supported by the COVID-19 EMA pandemic task force, a group that brings together experts from across the European medicines regulatory network to facilitate rapid and coordinated regulatory action on medicines and vaccines for COVID-19.
