COVID-19 Vaccination Take-Up

Summary

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.
