Facebook's vaccine misinformation policy reduces anti-vax information

Following years of growing vaccine opposition and several outbreaks of measles—a vaccine-preventable disease—Facebook established in 2019 its first policy to stop the spread of misinformation about vaccines. Researchers at the George Washington University wondered if the new policies actually worked to stop the spread of misinformation. Jiayan Gu, Ph.D. student along with Lorien Abroms, Professor of Prevention and Community Health and their colleagues created a new paradigm for evaluation of the policy. The team found that Facebook's policy did reduce people's interactions with vaccine misinformation.
