NCT06505993

Brief Summary

The purpose of this community-engaged study is to test the ability of county-level strategies to increase uptake of COVID-19 vaccination. In this study the key objective is to test whether health communication strategies or health communication + county-specific structural/environmental support increases COVID-19 vaccine uptake and changes perceptions and beliefs about the vaccination at the county-level.

Outcome Measures

Primary Outcomes (1)

  • COVID-19 vaccination uptake

    Change in \*county-level\* vaccination rates- to assess uptake, the investigators will ascertain the number of individuals in each county who received the COVID-19 vaccination during the intervention period as well as during an equivalent time frame prior to the intervention. This assessment will be obtained from existing, deidentified vaccination rate data maintained by the KY Department of Public Health. The primary outcome variable will be the number of individuals receiving vaccination.

    Baseline and 6 months

Secondary Outcomes (3)

  • COVID-19 Vaccination Behaviors

    Baseline and 6 months

  • COVID-19 Attitudes

    Baseline and 6 months

  • COVID-19 Risk Perceptions

    Baseline and 6 months

Study Arms (3)

Health Communication

EXPERIMENTAL

This intervention arm will include exclusively health communication messaging strategies that is both theory-based and community-targeted to encourage uptake of the COVID-19 vaccine delivered by trusted local communicators. Pre-identified theory-based components are attitudes, social norms, perceived behavioral control, response efficacy, and implementation intentions. The development process for the messaging will be based through a conjoint process of identification of theory- based determinants of decision-making relevant to the desired behavior change and a community-engaged process of identifying: a) community-specific messaging themes; b) trusted communicators within the target population; and c) community-specific messaging, imaging, and themes to achieve targeting.

Behavioral: Health Communication

Health Communication + Structural

EXPERIMENTAL

This intervention arm will include the conditions outlined and included in the health communication arm, however, they will be coupled with a series of structural and/or environmental intervention strategies as well, which are targeted to facilitate vaccine accessibility and uptake among adults in the randomly assigned study counties.

Behavioral: Health Communication + Structural

Standard of Care

NO INTERVENTION

No study-specific intervention strategies (as outlined above) will be implemented in control counties at the time of the study period. Any ongoing and/or pre-existing efforts within the scope of the project's outcomes will continue as it would have i.e. a health department operating a health fair.

Interventions

This multi-level intervention will include the defined health messaging intervention components, as well as a combination of structural-level intervention strategies targeted to better facilitate access to community-based vaccination delivery. Health organizations will receive a toolkit, which will include community-specific resources and training modules such as: up to date evidence-based vaccination guidance that can be delivered to patients; strategies for navigating conversations with patients about vaccination; any applicable reimbursement, insurance, or qualifying enrollment information specific to the healthcare organization; identifying locations that facilitate access for the community members; provided advertising to promote the locations and timing of the vaccinations; and generating community-based branding for all vaccination delivery based on the trusted information sources identified.

Health Communication + Structural

Participants will experience a coordinated social marketing campaign including targeted messaging related to vaccine education, self-efficacy, and informative resources to receive the COVID-19 vaccine. The intervention messaging will be strategically layered and disseminated to this intervention arm predominately via Facebook by trusted and local communicators in the study counties.
