Clinical Trial Summary
Coronavirus disease 2019 (COVID-19) has created a "state of emergency" for African Americans
in the US. Recent findings indicate 31% of adults self-reported "wait and see" of the
COVID-19 vaccine, of which 16% were African American. This project seeks to test the
feasibility and impact of a multi-layered, culturally-appropriate social marketing
intervention targeting COVID-19 vaccine hesitant (VH) African Americans to increase vaccine
confidence, uptake, and completion of multi-dose vaccine series in Nashville/Davidson County,
Tennessee. This study's novelty lies in being the first to assess feasibility and preliminary
efficacy of a multi-layered, culturally-appropriate social marketing intervention to promote
COVID-19 vaccination among African Americans in TN. Clinical significance is increased
vaccine uptake and decreased COVID-19 burden and disparities.
Description:
The goal of this application is to develop and test the feasibility and impact of a
multi-layered, culturally-appropriate social marketing intervention targeting COVID-19 VH
African Americans to increase uptake and completion of vaccine series in Nashville/Davidson
County, Tennessee (TN). Investigators will partner with members of National Association for
the Advancement of Colored People, Nashville Health Disparities Coalition, and Congregational
Health Education Network to serve as an advisory committee. Investigators will also partner
with Meharry Medical College (MMC) clinics and Tennessee Department of Health's (TDH)
Immunization Program.
Aim 1. Engage with key stakeholders to develop a multi-layered, culturally-appropriate social
marketing intervention targeting African Americans who are COVID-19 VH. Investigators will
adapt an existing message library using the Health Belief Model,Theory of Reasoned Action,
previous VH research, preliminary data of investigators, and feedback from community
partners. Next, investigators will conduct semi-structured interviews with 25-30 VH
individuals and 5-10 COVID-19 experts to elicit feedback on draft content. Qualitative data
will be collected and analyzed iteratively, informing successive intervention modifications
to cover a range of concerns for VH individuals, enhance message relevance, and determine
media outlets for dissemination. Next, investigators will pre-test intervention prototypes
with 16 COVID-19 VH individuals to make final modifications.
Aim 2a. Conduct a pilot study of the intervention and study protocol to demonstrate
feasibility and assess impact. Investigators will conduct a pilot study using an experimental
field trial design in three TN counties: Davidson County (1 intervention site) and Shelby and
Hamilton Counties (2 control sites). COVID-19 vaccine uptake, primary outcome, assessed
using: 1) aggregate data from partner clinics and TN immunization registry (TennIIS) and 2)
individual, pre-post data from a marketing firm using random digit dialing (RDD). H1:
COVID-19 vaccination rates will be higher for VH African Americans at intervention site
compared to control sites. Implementation outcomes are feasibility, fidelity, acceptability,
appropriateness, and penetration.
Aim 2b. To retrospectively explore knowledge, attitudes, intentions, and implementation
outcomes post-intervention. Investigators will use qualitative methods to identify perceived
acceptance of different types of media and webpage along with perceived change in knowledge,
attitudes, and intentions from African Americans by degree of VH. Investigators will also
explore appropriateness, feasibility, penetration, and fidelity as it relates to the social
marketing intervention from 3 providers, 3 community-based organization (CBO) staff, and 2
TDH staff. Participants will be identified using RDD and community partner networks.
