Several French social media influencers say they have received a mysterious financial offer to spread negative publicity about the Pfizer vaccine.
They say an agency claiming to be based in the UK has contacted them by email offering a "partnership".
He said the LinkedIn profiles of the agency's alleged employees he had managed to find later disappeared, but not before he noticed that "everybody there has worked in Russia".
It also asked him to spread among his followers a false claim that the death rate among the vaccinated by Pfizer is almost three times higher than among those who have received AstraZeneca.
In April, a European Union report said Russian and Chinese state-run media were systematically trying to sow public mistrust in Western Covid vaccines - a claim denied in Moscow.
