A Multiresource Event Model Developed to Increase Access to COVID-19 Vaccines in Pima County, Arizona, Summer 2021

In summer 2021, the Pima County Health Department (PCHD) developed and implemented a multiresource event model for vaccine clinics to increase access to COVID-19 vaccines and other resources, such as food, rental assistance, and public health services, in Pima County, Arizona, communities. The PCHD aimed to improve vaccine access in areas with vaccination rates <40% by involving community partners to plan a multiresource event with resources (eg, food, connection to economic resources, information on childcare, and heat relief)and incentives specific to community needs that could drive attendance. Resources would be made available to community members regardless of whether they received a COVID-19 vaccine at the event. The PCHD selected census tract 41.15 as the pilot group to apply the multiresouce COVID-19 vaccine event model. Census tract 41.15 is a heat-stressed area of Pima County comprising mostly Latino people and people with lower incomes and is an area with low vaccination rates for COVID-19. The vaccination rate increased in census tract 41.15 by 12.8 percentage points (absolute increase), starting at 33.9% on June 1, 2021, and increasing to 46.7% as of September 1, 2021. In addition, attendance at the pilot event versus attendance at previous events that did not use this model increased by >100%. The multiresource COVID-19 vaccine event, when held within a hyperlocal area and when the needs of residents in the community are considered, can improve vaccine uptake. This model provides a roadmap for COVID-19 vaccine delivery in areas of low uptake.
