Project 2VIDA! COVID-19 Vaccine Intervention Delivery for Adults in Southern California (2VIDA!)

Project 2VIDA! SARS-CoV-2 Vaccine Intervention Delivery for Adults in Southern California

The United States (U.S.) is the country with the largest number of infections and deaths due to COVID- 19 and racial/ethnic minorities are disproportionately affected. Acceptance and uptake of COVID-19 vaccines will be instrumental to ending the pandemic. To this end, 2VIDA! (SARS-CoV-2 Vaccine Intervention Delivery for Adults in Southern California) is a multilevel intervention to address individual, social, and contextual factors related to access to, and acceptance of, the COVID-19 vaccine by implementing and assessing a COVID-19 vaccination protocol among Latino and African American (AA) adults (>18 years old) in San Diego. 2VIDA! builds on our previous CBPR efforts and centers on conducting COVID-19 Individual awareness and education, linkages to medical and supportive services, and Community Outreach and Health Promotion in the intervention sites (Phase 1); and offering the COVID-19 vaccine to Latino and AA adults (>18 years old) in federally-qualified health centers and pop-up vaccination stations in communities highly impacted by the pandemic and identifying individual and structural barriers to COVID-19 immunization (Phase 2).

Detailed Description

As of January 2021, the World Health Organization (WHO) reports that 89 million cases of COVID-19 (SARS- CoV-2) have been confirmed and have resulted in more than 1.9 million deaths globally. Currently, the United States (U.S.) is the country with the largest number of infections and deaths due to COVID-19, with a total of 22 million infections and 373,167 deaths. Furthermore, early findings that have examined COVID-19 demographics show that racial and ethnic minorities in the U.S. are bearing a disproportionate number of COVID-19 cases and deaths irrespective of geographic region. While there's no evidence that people of color (POC) have genetic or biological factors that make them more likely to be affected by COVID-19, they are more likely to have underlying health conditions, live in multi-generational homes, live in densely populated areas, have limited access to healthcare, and have jobs that are considered essential and involve interaction with the public. All of these factors contribute to higher rates of infection and adverse outcomes due to COVID-19. Although COVID-19 preventive behaviors such as hand washing, mask wearing, and social distancing have been shown to be effective in curbing the spread of the virus, acceptance and uptake of COVID-19 vaccines will be instrumental to ending the pandemic. However, public confidence in vaccination is fragile, especially among racial and ethnic minorities. To this end, we have formed an intervention working group comprised of representatives from community and academic organizations to address challenges in COVID-19 vaccination uptake among Latino and African American (AA) communities in Southern California by using a community-based participatory research (CBPR) approach. Project 2VIDA! (SARS-CoV-2 Vaccine Intervention Delivery for Adults in Southern California), is a multilevel intervention to address individual, social, and contextual factors related to access to, and acceptance of, the COVID-19 vaccine among Latino and AA adults (>18 years old) across six highly affected communities in Southeast San Diego. 2VIDA! seeks to implement and assess a COVID-19 vaccination protocol to increase interest and uptake of COVID-19 vaccine, provide COVID-19 vaccines in the community, and establish a model for the rapid vaccination of Latino and AA adults that could be generalizable to other highly affected communities. 2VIDA! builds on our previous CBPR efforts and centers on conducting COVID-19 community outreach and health promotion, Individual awareness and education, and linkages to medical and supportive services and offering the COVID-19 vaccine to Latino and AA adults (>18 years old) in community health centers (CHC) and mini-vaccination stations in communities highly impacted by the pandemic in San Diego County.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Intervention; We will use a 2-armed randomized controlled trial (RCT) where Latino and AA adults >18 years or older from six participating communities and surrounding community health centers (CHC) will be assigned to the 2 VIDA! intervention (n=3 CHC; N=500 participants) or to the control site (e.g., standard of care) (n=3 CHC; N=500 participants). The two major components of the 2VIDA! intervention are: COVID-19 Individual Awareness and Education, COVID-19 Community Outreach and Health Promotion, COVID-19 Individual Health Education and Linkages to Medical and Supportive Services, and pop-up vaccination stations in Latino and AA communities.	Behavioral: COVID-19 Individual Awareness and Education.; The 2VIDA! working group has developed culturally competent COVID-19 educational and outreach materials (available printed and electronically) in English and Spanish that are written at the 8th grade level (the average reading level of adults in the United States) that peer-health educators will distributed to community members during their visits to the participating SYH community centers, door-to-door, local supermarkets, and CBO's in the selected communities. These materials have general information on COVID-19 as well as educational information and resources regarding COVID-19 prevention, symptoms, testing, contact tracing, COVID-19 vaccine (how it works, technology used, administration [2-dose series and importance of vaccine completion]), safety concerns, benefits, dispelling common misconceptions and misinformation, and other topics identified based on community needs. This information will be updated monthly to ensure the most up to date information.; Behavioral: COVID-19 Community Outreach & Health Promotion.; Peer-health educators will work with local CBO's and facilitate a combination of live broadcast sessions, pre-recorded webinars, social media posts, and other outreach activities in English and Spanish reaching community members with information on the above COVID-19 related topics as well as other identified needs such as what to do if a family member is infected and where you can get the COVID-19 vaccine. The goal is to reach 10,000 viewers (per session) in the various social media platforms in the three randomly selected communities.; Behavioral: COVID-19 Individual Health Education & Linkages to Medical and Supportive Services.; SYHealth will establish a COVID-19 Resource Center within the participating health centers in the three randomly selected communities (intervention sites only) providing individual COVID-19 related health education and linkages to medical and supportive services for patients and community members in need of additional education and support regarding COVID-19 disease and COVID-19 vaccine.; Biological: Pop-up community vaccination sites; We will offer the COVID-19 vaccine at the participating SYHealth community health centers and pop-up vaccination stations that will be set-up in these communities (intervention sites) as part of the interventions efforts to increase access and uptake of the COVID-19 vaccine. We have identified various open spaces (e.g., public parks) in these communities to set-up the vaccination stations. Additionally, data will be collected to assess individual, social, and contextual factors related to access, acceptance, and uptake of the COVID-19 vaccine.The survey will last approximately 10-15 minutes and will be self-administered in both English and Spanish. Following the survey participants will be offered the COVID-19 vaccine and will be made an automatic appointment for the 2nd dose (4-week follow-up) and will be asked to complete a 5 min survey during the follow-up visit.
No Intervention: Standard of care; The standard of care for vaccine delivery at the control sites. This includes individuals who make an appointment on their own or receive the vaccine at a health center and may receive information about the vaccine from their primary healthcare provider.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in COVID-19 Vaccine acceptance	Agreement with value statements of the vaccine (control COVID-19, help avoid restrictions, never accept it, should be mandatory).

Past 12 months, baseline (current) and follow-up (4-weeks).
Change in Vaccine Hesitancy	Based on the definition of the Strategic Advisory Group of Experts (SAGE) Working Group on Vaccine Hesitancy (WG), hesitancy refers to "delay in acceptance or refusal of vaccination despite availability of vaccination services.
