Majority of anti-vaxx ads on Facebook are funded by just two organizations

Study finds Robert F Kennedy Jr's World Mercury Project and Larry Cook's Stop Mandatory Vaccinations bought 54% of ads

The majority of Facebook ads spreading misinformation about vaccines are funded by two organizations run by well-known anti-vaccination activists, a new study in the journal Vaccine has found.

The World Mercury Project chaired by Robert F Kennedy Jr, and Stop Mandatory Vaccinations, a project of campaigner Larry Cook, bought 54% of the anti-vaccine ads shown on the platform during the study period.
