Information, Perceptions and Health Behavior (2021-2022)

Health decisions and behavior are often intertwined with perceptions influenced by information access, culture and social norms, and policies that may elicit acceptance or resistance. For example, vaccines have been a savior invention for individual health and the greater society, but doubts about vaccines’ necessity, efficacy and safety have endured since the 1800s. Vaccine hesitancy has led to suboptimal immunizations globally. In the U.S., only 70% of children complete the recommended childhood vaccine series and 34% of adults regularly receive vaccinations for seasonal influenza.

Misinformation and antivaccine sentiments in recent years have caused resurgences of diseases that were eliminated or nearly eradicated. While COVID-19 persists, the public’s intent to vaccinate is unclear and changing. Of note, racial and ethnic minorities with higher infection susceptibility and mortality often have lower confidence and acceptance for vaccines, perpetuating chronic disparity. 

This project team examined how vaccine acceptance for COVID-19 and other diseases change over time; compared individual, societal and vaccine-specific barriers and motivators to vaccination; and analyzed how language framing and data presentation influence vaccination decisions. The team used surveys, focus groups and in-depth individual interviews to determine the factors that may be affecting levels of hesitancy, including risk perception, social norms and sources of information. Their work offered policymakers comprehensive, up-to-date insights and recommendations for planning, executing and monitoring immunization programs.
