Precision Vaccine Promotion in Underserved Populations

University of Southern California·interventional·Posted Sep 13, 2022·Updated Oct 1, 2024

In Brief

A clinical study evaluating Text messaging for Influenza and Vaccine Hesitancy. Completed, enrolled 228,831 participants across 1 site.

Detailed Summary

Previous studies have shown that low-cost, behavioral nudges through texting can increase influenza vaccination uptake compared to usual care. However, there are limited studies that evaluate the effect of decreasing barriers to scheduling, especially within safety net populations. The setting for this study, DHS, is the second largest public delivery system in the country and serves approximately half a million diverse patients that are eligible for vaccinations annually. This pilot study (one arm in a larger randomized controlled trial) will examine the effect of text messages highlighting MediCal health plan transportation resources (vs standard text messaging) on influenza vaccination rates in adults during the 2022-2023 flu season.
