Impacting delayed pediatric influenza vaccination: a randomized controlled trial of text message reminders.

BACKGROUND: Influenza vaccination coverage is low- especially among low-income populations. Most doses are generally administered early in the influenza season- yet sustained vaccination efforts are crucial for achieving optimal coverage. The impact of text message influenza vaccination reminders was recently demonstrated in a low-income population.

PURPOSE: To determine the impact of educational plus interactive text message reminders on influenza vaccination of urban low-income children unvaccinated by late fall. DESIGN: Randomized controlled trial.
