The tweet follows a ban on importing the vaccines from the two countries, with Khamenei saying they were “completely untrustworthy.” “The import of American and British vaccines is prohibited… It is not unlikely they would want to contaminate other nations,” the Iranian leader said in a speech, which was also posted on Twitter. He also said: “Given our experience with France’s HIV-tainted blood supplied, French vaccines aren’t trustworthy either.” The tweet has since been taken down on Khamenei’s English and Arabic accounts, but is still available on his Persian account. Twitter said the tweet violated the social media platform’s rules.
