Examining How a Text Message-based Educational Intervention Influences COVID-19 Testing

In this Phase III study, the investigators will build off of the Phase II embedded study with some adjustments to the design to address new research priorities that examine an intervention that is network informed and delivered through community health worker interactions plus digitally-delivered intervention content with the goal of increasing COVID-19 testing and vaccination. This model, if proven effective, can be scaled up to address COVID-19 and other future pandemics. The investigators will utilize the sample of intervention priority census block groups (PBGs) used in Phase II and will recruit and enroll participants not previously enrolled in either phase I or II from these PBGs using convenience sampling methods. The investigators will use a historical control group consisting of participants from our control arm in Phase II who completed both their baseline and follow-up surveys embedded in the study.
