Official title
COVID-19 Vaccination Take-Up in a County-Run Medicaid Managed Care Population
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
In this work, the investigators are partnering with Contra Costa Health Services (CCHS), the department of health in Contra Costa County, CA, to measure COVID-19 vaccinations and other COVID-19 related preventive health behaviors in the county's Medicaid managed care population. This work will test ways to increase COVID-19 vaccine uptake. The investigators hypothesize that small financial incentives and other low-cost behavioral nudges can be used to increase vaccine uptake and reduce disparities in uptake among diverse racial/ethnic minority populations.
