Evaluation of the COVID-19 Vaccination Campaign in Latinx Communities in California, June 2021-May 2022.

Objectives: The 12-month vaccination campaign was launched to increase COVID-19 vaccination rates in Latinx populations in California by expanding community outreach. The objectives of this evaluation were to (1) determine predictors of vaccination rates and (2) identify barriers to vaccination and potential solutions.

Methods: Five community partners in California serving Latinx populations with high social vulnerability participated in the campaign. Community health workers were hired to deliver outreach (virtual, one-on-one, group based, and information dissemination), vaccinations, and supportive services. We collected data on outreach strategy used (method and location), number of vaccinations provided and reasons for delay, and number of times that supportive services were provided. We used regression models to assess significant predictors of vaccinations and supportive services.

Results: Community health workers (N = 146) hired from June 1, 2021, through May 31, 2022, performed outreach engagements (n = 6297) and supportive services (n = 313 796), resulting in 130 413 vaccinations and 28 660 vaccine appointments. The number of vaccinations administered was significantly higher at events in which supportive services were provided versus not provided (coefficient = 34.02; 95% CI, 3.34-64.68; = .03). The odds ratio of supportive services was 3.67 (95% CI, 1.76-7.55) during virtual outreach and 2.95 (95% CI, 2.37-3.69) during one-on-one outreach ( < .001 for both) as compared with information dissemination encounters. Vaccination concerns were reported among 55.0% of vaccinated survey respondents (67.7%, vaccine confidence; 51.7%, access).

Conclusions: Supportive services facilitate vaccinations, ease transportation and time barriers, and instill confidence among working-class racial and ethnic minority populations.
