Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study is to be conducted over the 1st season (September 2017-April 2018) as an effectiveness trial and the 2nd (September 2018-April 2019) as a replication study. This approach tests that the intervention effects can be replicated across seasons, during which the severity and incidence of influenza disease may vary. Eligible parents will have a child who received his/her first vaccine dose and is in need of 2 doses that season. Current recommendations require 2 doses for certain children 6 months through 8 years old. Within each practice site, parents will be randomized to receive either: 1) text message reminders embedded with influenza vaccine health-literacy promoting information, or 2) usual care. Randomization is to be stratified by practice site, age (6-23 months, 2-8 years) and language (Spanish, English).
