Facebook fact checks Liz Wheeler video about hepatitis B vaccine for newborns: Conservative commentator Liz Wheeler shared a video speaking about the backlash she faced when she declined the hepatitis B vaccine for her newborn child. She captioned the video, "Why is it that, as soon as a mom trusts her intuition and pushes back against the 'science,' pediatricians start bullying her?" Facebook flagged the video for containing "false information" and linked to a Health Feedback article that claimed the hepatitis vaccine was safe for children under six years old. Fact-checked posts lose exposure and are negatively affected by the platform's algorithm.
