Trusted sources for COVID-19 testing and vaccination: lessons for future health communication

Promoting COVID-19 vaccination (both the primary series and boosters) remains a priority among healthcare professionals and requires understanding the various sources people trust for acquiring COVID-19 information.

From October 2021 to May 2022, we interviewed 150 people who called 2-1-1 helplines in Connecticut and North Carolina about their COVID-19 testing and vaccination experiences in order to (1) better understand where people obtain trusted COVID-19 health information and (2) identify how public health professionals can share emergency health information in the future. We used a mixed methods approach in which semi-structured qualitative interviews and survey data were collected in parallel and analyzed separately.

Participants were mostly female (74.0%), Black (43.3%) or White (38.0%), and had a high school degree or higher (88.0%). Most had prior COVID-19 testing experience (88.0%) and were vaccinated (82.7%). A variety of information sources were rated as being very trustworthy including medical professionals and social service organizations. We found that repetition of information from multiple sources increased trust; however, perceived inconsistencies in recommendations over time eroded trust in health communication, especially from government-affiliated information sources. Observations such as seeing long lines for COVID-19 testing or vaccination became internalized trusted information.

Public health professionals can leverage the reach and strong community ties of existing, reputable non-government organizations, such as physician groups, schools, and pharmacies, to distribute COVID-19 information about vaccination and testing.
