Facebook's Policies on Immunization Misinformation

Evaluating the Efficacy of Facebook's Vaccine Misinformation Content Removal Policies

Social media platforms have attempted to remove misinformation about vaccinesbecause it obstructs efforts to end the covid-19 pandemic.

We examined whether social media platforms have attempted to remove misinformation about vaccines because it obstructs efforts to end the covid-19 pandemic.

We examined whether social media platforms have attempted to remove misinformation about vaccinesbecause it obstructs efforts to end the covid-19 pandemic.

We found that posts and engagement in anti-vaccine pages were reduced to 29% and 23% of pre-policy levels, respectively, but recovered over the subsequent six months.

Posts and engagement in pro-vaccine pages were also reduced to 68% and 30% of pre-policy levels, but recovered over the subsequent six months.

Low-credibility content became more prevalentin anti-vaccine pages and groups, and high-credibility content became lessprevalent in pro-vaccine pages.

Links between anti-vaccine pages and coordinated inauthentic behavior were also reduced.

Our results suggest that social media platforms were only partially successful in removing misinformation about vaccines.
