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.

Detailed Description

The intervention trial will be a community-based, three-arm cluster randomized controlled trial. The three arms are: (1) multilevel invention (vaccine communication campaign + community-level structural intervention),(2) health communications only intervention, and (3) control/standard of care. Randomization will take place at the county level. The 15 participating counties will first be matched into blocks of three, with each block being matched as closely as possible on recent county influenza vaccination rates. After matching, the three counties within each matched block will be randomly assigned to one of the three study arms. This technique of randomizing to study arm within each matched block of counties increases confidence that community-level factors that might influence vaccine uptake are equally distributed across study arms. Following randomization, the intervention process will begin in counties in the multilevel and communication campaign intervention arms. Assessment of primary and secondary study outcomes will take place 6 months after initiation of the intervention. Finally, after assessment of outcomes is complete, the intervention components will be offered to the control counties.

Arm && Interventions
GroupInterventionDescription
Health CommunicationHealth CommunicationThis 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.
Health Communication + StructuralHealth Communication + StructuralThis 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.
Primary Outcome Measures
NameTimeMethod
COVID-19 vaccination uptakeBaseline and 6 months

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.

Secondary Outcome Measures
NameTimeMethod
COVID-19 AttitudesBaseline and 6 months

The investigators will assess individual-level vaccination attitudes and beliefs with a survey among adults in each study county. Participants will be asked to self-report their responses to following statements utilizing a 4-point Likert scale (1= strongly disagree, 2= disagree, 3= agree, 4= strongly agree):

1. "I feel safe about getting the COVID-19 vaccine."

2. "The COVID-19 vaccine may cause short term problems, like fever or discomfort."

3. "The COVID-19 vaccine is being pushed to make money for drug companies."

4. "The COVID-19 vaccine was not tested enough for safety."

5. "The COVID-19 vaccine may cause lasting health problems."

6. "I am concerned that the COVID-19 vaccine will cost more than I can pay."

7. "The COVID-19 vaccine was developed too quickly."

COVID-19 Risk PerceptionsBaseline and 6 months

The investigators will assess individual-level risk perceptions about vaccination with a survey among adults in each study county. Participants will be asked to self-report their responses to following questions with a 4-point Likert scale:

1. "How likely are you to get COVID-19 in the next 6 months?" 1= very unlikely to 4= very likely

2. "How afraid are you of getting COVID-19 in the next 6 months?" 1= not afraid at all to 4= extremely afraid

3. "If you were to get COVID-19 in the next 6 months, how serious would it be?" 1= not serious at all to 4= extremely serious

COVID-19 Vaccination BehaviorsBaseline and 6 months

The investigators will assess individual-level vaccination behaviors with a survey among adults in each study county. To capture, participants will be asked to self-report their responses to following statements with multiple choice answer choices provided to allow for quantitative analysis: 1) "Have you or do you think you have had COVID-19?" 1= Yes I was tested or a doctor diagnosed me; 2= Maybe I had some symptoms but was not tested; 3= No. 2) "How many times have you had COVID-19?" 1= Once, 2= Twice, 3= Three or more times. Additionally, the investigators will use a 4-point Likert scale (1= strongly disagree, 2= disagree, 3= agree, 4= strongly agree) to assess respondent likeliness of intention to vaccinate with either a COVID-19 booster, or COVID-19 vaccine, in the next 12-months.
