University of Chicago Study Discovers Link Between Language and Vaccine Hesitancy


The Hong Kong Jockey Club University of Chicago Academic Complex | University of Chicago Francis and Rose Yuen Campus in Hong Kong (UChicago Yuen Campus) today announced the results of a research exploring the link between language use and vaccine hesitancy, suggesting that a simple language intervention could help boost vaccination rates, especially when presenting information to people in bilingual populations. The study was initiated by UChicago scholars and facilitated with the help of the UChicago Yuen Campus’ staff in Hong Kong, where many residents are able to speak both their native language Cantonese and English.

The study commenced amid global conversations about building public trust in the safety and effectiveness of COVID-19 vaccines. Hong Kong was seen as an ideal case study by the researchers due to its large bilingual population and relatively low vaccine uptake rate at the time the study was done from March to April 2021.

Led by psychology postdoctoral researcher Janet Geipel and co-authored by doctoral student Leigh Grant and professor Boaz Keysar from the University of Chicago, the UChicago Yuen Campus recruited 611 participants and administered the survey to facilitate the report’s findings.

The study found that participants who read materials about the vaccine in English showed higher willingness to get vaccinated than those who only read in Cantonese. However, the researchers say that their larger finding should be thought about not in terms of one case study, but as an illustration of language’s power as a tool for enhancing trust.

According to UChicago scholars, the language which might be associated with more public trust than another should be the one that is used when communicating about things like vaccines.

“Public health campaigns therefore could use such language interventions strategically to boost vaccination uptake and other beneficial preventative behaviors such as cancer screening,” according to the researchers’ conclusion in the report. “Language interventions could contribute towards achieving the United Nations Sustainable Development Goal of health and well-being.”

The full details of the report was published in Nature: Scientific Reports on January 7, 2022.
