There is currently no internationally approved vaccine to prevent COVID-19, the illness caused by the new coronavirus, which has killed over 1 million worldwide.
France's public research body Inserm, which is in charge of the project, did not name the vaccines that would be assessed and said it was currently holding discussions with drugmakers, adding it would pick the “most promising” candidates for the trials.
More than 150 potential vaccines are being developed around the world and tested to stop the COVID-19 pandemic, with 38 in human trials, according to the World Health Organization (WHO).
