Interventions: Behavioral: Health System Vaccination Text Messages and Provider Education

Brief Summary: The study aims to assess the impact of a multicomponent intervention to support Primary Care Provider (PCP) outreach to promote COVID-19 vaccination among vulnerable patients in and near Worcester, MA via a pragmatic, cluster randomized trial.

Detailed Description: The goal of this study is to increase uptake of the COVID-19 vaccine among vulnerable populations through systematic primary care (PCP or clinic) text message outreach to unvaccinated patients, information provision via a study website, and resources to support PCPs.

The clinical trial will randomize 14 primary care clinics from three health systems in the Worcester, Massachusetts area to intervention or control. Eligible patients seen at a study clinic randomized to the intervention will receive a series of text messages from their PCP or primary care clinic recommending a study website as a trusted source of information about the COVID-19 vaccines and information on how and where to schedule a vaccination.

Providers at a study clinic randomized to the intervention will be provided resources to support their conversations with unvaccinated patients during the intervention. Resources will include access to the study website, factsheets to share with vaccine hesitant patients, prescription pads to be used to "prescribe' the website, and an electronic "smartphrase" that can automatically add information about the study website and how to schedule a COVID-19 vaccination to patients' After Visit Summary and/or clinic note.
