There’s been growing backlash against the anti-vaxxer movement due to a measles outbreak in Oregon. It’s safe to say the outbreak is a direct correlation since vaccines help prevent these diseases.
Advertisements on Facebook promoted by anti-vaxxer organizations have been specifically targeting pregnant women. Popular parenting groups on Facebook are also a source for misinformation on vaccines. A Facebook spokesperson told Business Insider:
We are committed to accurate and useful information throughout Facebook. We remove content that violates our Community Standards, down-rank articles that might be misleading, and show third-party fact-checker articles to provide people with more context. We have more to do, and will continue efforts to provide educational information on important topics like health.
It’s unknown when Facebook plans to remove content or if that process has already begun.
