Multiple France-based influencers with sizable audiences on Twitter, Instagram and other platforms said they were contacted with offers of hush-hush payments to make bogus claims about supposed deadly Pfizer vaccine risks.

YouTuber Léo Grasset, among those contacted, said the shady advertising agency that sought to recruit him “wanted me to talk about the Pfizer vaccine in a way that would be detrimental to the Pfizer vaccine reputation.”He and others said they refused. They got a thumbs up Wednesday from French government spokesman Gabriel Attal.

“I want to salute the great responsibility of these young YouTubers or influencers who not only didn't fall for this and didn't, through cupidity, allow themselves to be manipulated but also denounced it publicly," Attal said. “I really want to salute that.”Grasset, who has 1.1 million subscribers on YouTube, said he and other social media and internet content-creators are “at the center of something going on like an information war.”The person who contacted Grasset identified himself as Anton and said his ad agency has a “quite considerable” budget for what he described as an “information campaign” about “COVID-19 and the vaccines offered to the European population, notably AstraZeneca and Pfizer.”Specifically, “Anton” asked for a 45- to 60-second video on Instagram, TikTok or YouTube to say that “the mortality rate of the Pfizer vaccine is 3 times greater than the AstraZeneca” and querying why the European Union is buying it.

He refused in a follow-up email to divulge who is financing the campaign, saying: “The client prefers to remain incognito.”Instructions he sent also said that if influencers agreed to take part then they shouldn't say that they were being sponsored and should "present the material as your own independent view.”Grasset shared the email exchanges with The Associated Press. He said that given his large YouTube following, he might have earned tens of thousands of euros (dollars) had he agreed to take part.

Instead, he wrote back that “I can't work for a client that won't give its name and who asks me to hide the partnership.”The AP sent emails requesting comment to a contact address listed on ad agency's website and to the email address used by “Anton.” Neither elicited a response.
