Europe's medicines agency announced on Tuesday it had began reviewing the COVID-19 vaccine developed by French pharmaceutical company Sanofi  and Britain's GlaxoSmithKline.


The decision to start the "rolling review" of the vaccine, Vidprevtyn, was based on preliminary results from lab studies and early stage clinical trials in adults, the European Medicines Agency (EMA) said in a statement.

Late-stage global trials for the protein-based coronavirus vaccine candidate began in May.

Sanofi and GSK hope to get approvals by the end of 2021 after early-stage results showed the vaccine produces a robust immune response. 

"EMA will assess the compliance of Vidprevtyn with the usual EU standards for effectiveness, safety and quality," the regulator said, without giving details on data it had received so far or an expected timeline for approval.

EMA's rolling reviews are aimed at speeding up the approval process by allowing researchers to submit findings in real time before final trial data is available.

Influenza vaccines

Sanofi said other rolling reviews of its vaccine were also about to start in Britain, Canada and Singapore, as well as with the World Health Organization.

Vidprevtyn uses the same technology as one of Sanofi's seasonal influenza vaccines. It will be coupled with an adjuvant, a substance that acts as a booster to the shot, made by GSK.

Other COVID-19 vaccine candidates in the EU's rolling review are those from CureVac (Germany,) Novavax (US,) Sinovac (China) and Russia's Sputnik V, developed by the Gamaleya Center of Epidemology and Microbiology in Moscow.
