Trial Outcomes & Findings for Impact of LA-CEAL HALT COVID-19 Ambassador Program on Likelihood to Vaccinate (NCT NCT04930965)

Last Updated: 2024-01-18

Results Overview

Vaccine likelihood will be measured using a single question adapted from the CEAL Common Survey (i.e., "On a scale from 1 to 7, with 1 being 'not at all likely' and 7 being 'very likely', how likely are you to get a COVID-19 vaccine in the next month?"), with "likely to vaccinate" defined as a score of 5-7.
