Facebook bans firm behind Pfizer, AstraZeneca vaccine smear campaign

Facebook said Tuesday that it has removed hundreds of accounts linked to a mysterious advertising agency operating out of Russia that sought to pay social media influencers to smear COVID-19 vaccines made by Pfizer and AstraZeneca.

A network of 65 Facebook accounts and 243 Instagram accounts was traced back to Fazze, an advertising and marketing firm registered in the United Kingdom. Facebook said Fazze's work was primarily done from Russia on behalf of an unknown client. The network used fake accounts to spread misleading claims that disparaged the safety of the Pfizer and AstraZeneca vaccines. One claimed AstraZeneca's shot would turn a person into a chimpanzee. The fake accounts targeted audiences in India, Latin America and, to a lesser extent, the U.S., using several social media platforms including Facebook and Instagram.
