Celebrity Twitter endorsement for an immunization public health campaign in Indonesia
Researchers conducted a randomized evaluation on measuring the impact of celebrity Twitter endorsement for a child immunization campaign on the public’s opinion and behavior towards immunization. Celebrity endorsement increased Twitter engagement with the immunization campaign, primarily when celebrities authored messages themselves and did not explicitly cite credible public health sources. Celebrity endorsement led to increased communication and knowledge about health behaviors in individuals’ communities, though there was no impact on an individual’s immunization decisions for their children.
