Following on the heels of Pinterest, Facebook is launching a new initiative aimed at combating anti-vaccine misinformation. Moving forward, whenever Facebook users search for vaccine-related content, including through groups and hashtags, the social network will display a card that prompts those individuals to instead obtain information from a credible source. In the US, the notification will direct people to the website for the Centers for Disease Control and Prevention (CDC). In other parts of the world, those same notifications will send people to the World Health Organization (WHO). Instagram will do the same on its platform.
