Sponsor's own description
This study is related to a previous study, Clinicaltrials.gov ID: NCT02924467. There are some modifications in relation to the intervention arms as well as the use of a different cohort, thereby justifying the second submission to Clinicaltrials.gov. This trial is taking place in New York State, through partnership with the New York State Health Department (excluding New York City), and Colorado. Each state will have it's own Clinicaltrial.gov submission -- this was decided as some of the intervention components are different enough that separate registrations were warranted. Despite U.S. guidelines for influenza vaccination of all children starting at 6 months, only about half of children are vaccinated annually leading to substantial influenza disease in children and spread of disease to adults. A major barrier is that families are not reminded about the need for their children to receive influenza vaccination. The investigators will evaluate the impact of patient reminder/recall (R/R) performed by state immunization information systems to improve influenza vaccination rates by using 4 clinical trials (2 per state) in two different states. The investigators will assess effectiveness and cost-effectiveness of 1) autodialer R/R 2) text messages R/R 3) mailed postcard R/R as compared to 4) standard of care control (no R/R).
