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.
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.

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.
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.

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.
Time frame: Baseline and 6 months
COVID-19 Vaccination Behaviors
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.
Time frame: Baseline and 6 months
COVID-19 Attitudes
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 Perceptions
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
