Twitter restricts Dr. Brett Giroir's tweet: Former Assistant Secretary for Health Dr. Brett Giroir shared a tweet saying, "It's now clear #COVID19 natural immunity is superior to #vaccine immunity, by ALOT. There's no science justification for #vax proof if a person had prior infection. @CDCDirector @POTUS must follow the science. If no previous infection? Get vaccinated!" The tweet included a link to a study comparing SARS-CoV-2 natural immunity to vaccine-induced immunity. Twitter censored the post, claiming it was "misleading," according to a screenshot shared on Alex Berenson's Substack. The notice said, "Learn why health officials recommend a vaccine for most people." The platform prevented users from sharing or interacting with the tweet. Giroir said Twitter never responded to his appeal.
