Key takeaways:
- The three most prominent U.S. anti-vaccination organizations -- National Vaccine Information Center, Children’s Health Defense, and Informed Consent Action Network -- are using Facebook and other major social media platforms to lay the groundwork for widespread coronavirus vaccine rejection.
- Facebook allows these groups to identify their organizations with descriptors like “Educational Research Center” and “Medical & Health” organization.
- Facebook’s current policies surrounding vaccine misinformation include de-ranking accounts and posting “educational units” to some anti-vaccine misinformation. But the Facebook pages for NVIC, CHD, and ICAN and those groups' leaders do not contain any warnings from Facebook about the organization’s purposes.
- The groups' pages are rife with vaccine conspiracy theories and other coronavirus misinformation. For example, NVIC has promoted conspiracy theories about Bill Gates and vaccine development, CHD has promoted the falsehood that wearing masks does not reduce the likelihood of coronavirus spread, and ICAN’s leader has claimed even the “biggest vaccine advocates in the country” are “sounding the alarm” on coronavirus vaccine development.
- Facebook pages for NVIC, CHD, ICAN and their associated leaders and media projects have a combined more than 950,000 followers. This represents the tip of the iceberg; according to a recent report, anti-vaxxers have a combined Facebook following of 58 million people.
- Academic research on approaches similar to Facebook’s to counter anti-vaccine misinformation suggests Facebook’s current policies will not be effective in countering coronavirus vaccine misinformation.
- A growing share of Americans say they will refuse to receive a coronavirus vaccine, which could greatly harm efforts to get the disease under control in the U.S.
As novel coronavirus cases spike in the U.S. and numerous efforts are underway to develop a vaccine, the most prominent U.S. anti-vaccination organizations are using Facebook and other social media platforms to poison the well against a potential vaccine -- even though the consequence of widespread vaccination rejection in the U.S. would be an additional public health disaster.
In March 2019, Facebook said it “implemented new policies to de-rank accounts spreading vaccine misinformation in their search results,” according to ABC News. Later that year, Facebook and Instagram (which Facebook owns) announced they had partnered with the WHO and Centers for Disease Control and Prevention to “start posting educational units about vaccines on ‘vaccine-related searches on Facebook, Facebook Groups and Pages that discuss vaccines, and Invitations to join Facebook Groups that discuss vaccines.’” In theory, Facebook bans ads that include vaccine misinformation, but enforcement has been spotty. Anti-vaccine content on Facebook may be fact-checked by Facebook’s third-party fact-checking program. Additionally, Facebook has a policy to take action against coronavirus misinformation, though the methods Facebook uses have been criticized as ineffective and scattershot in their application. After Buzzfeed News identified anti-vaccine ads in January, a Facebook spokesperson paradoxically responded, “Facebook does not have a policy that bans advertising on the basis that it expresses opposition to vaccines. Our policy is to ban ads containing vaccine misinformation."
There’s evidence that even brief exposure to anti-vaccination information changes attitudes. According to a 2010 study published in Health Psychology, “Accessing vaccine-critical websites for five to 10 minutes increases the perception of risk of vaccinating and decreases the perception of risk of omitting vaccinations as well as the intentions to vaccinate.” The phenomenon does not appear to work in reverse: A study that attempted to change attitudes with “direct pro-vaccination messages” found that those messages actually reinforced misguided beliefs. In fact, common ways that anti-vaccine information is countered are typically ineffective. A 2014 study published in Pediatrics tested the following four messaging strategies “designed to reduce vaccine misperceptions and increase vaccination rates for measles-mumps-rubella (MMR)”:
