School-Located Vaccine Clinics: An Effective Strategy for Expanding Access to COVID-19 Vaccines in Los Angeles County.

A key component of decreasing severe disease, hospitalizations, and death due to COVID-19 has been increasing vaccine accessibility to residents in communities where access to health care is poor and residents are at increased risk of poor health outcomes. Driven by the expansive geography and diverse population it serves, the Los Angeles County Department of Public Health built an extensive school vaccination network by partnering with the county's roughly 3000 schools and vaccine providers. We report on the process of building this network and its impact on vaccination coverage. We describe a unique equity metric (HPI+) that used a combination of the Healthy Places Index (HPI) and COVID-19 transmission and vaccination data to prioritize school-located vaccination efforts. More than 328 991 doses of COVID-19 vaccine were administered at 1050 schools in Los Angeles County from April 15, 2021, through June 18, 2022. Nearly 10% of all doses administered to children aged 5-11 years in Los Angeles County were at school-located vaccine clinics. Most vaccine clinic days (77.3%) were held at schools in HPI+ zip codes. Most doses (68.3%) were administered in HPI+ regions and to people aged ≥12 years (70.3%). Vaccinating the community at schools is an effective public health intervention; however, increased outreach efforts were required in HPI+ regions to ensure equitable access to vaccines. This case study can be used to replicate public health interventions using schools to support access to health care services for students and the surrounding community. [ABSTRACT FROM AUTHOR]
