Researchers at Stanford University—in partnership with several nonprofits that have received government funding—worked with social media platforms to flag and suppress commentary on COVID vaccines, science, and policy that contradicted public health officials' stances, even when that commentary was true.

This new information comes from yet another Twitter Files entry of screenshotted emails and reports from independent journalist Matt Taibbi that reveals the back and forth between the Stanford-led Virality Project and receptive Twitter executives about policing alleged COVID misinformation on its platform.

Beginning in February 2021, and continuing with regular reports, Virality Project researchers encouraged Twitter to expand its misinformation policies to include true reports of vaccine side effects, criticism of vaccine passport systems for their imposition on rights and freedoms, and even discussion of legitimate scientific research on breakthrough infections on natural immunity.
