Summary
School-located influenza vaccination clinics increased vaccination rates for elementary students. Offering electronic consent options improved uptake, with minimal substitution for primary care in suburban areas.
Area of Science:
- Public Health
- Epidemiology
- Vaccinology
Background:
- Influenza vaccination is crucial for child health.
- School-located influenza vaccination (SLIV) clinics offer a convenient delivery method.
- Assessing the impact of different consent methods on vaccination rates is important.
Purpose of the Study:
- To evaluate the effectiveness of school-located influenza vaccination (SLIV) clinics in increasing overall influenza vaccination rates among elementary school children.
- To compare the impact of web-based and paper consent forms on vaccination uptake.
- To determine if SLIV substitutes for or complements primary care vaccinations.
Main Methods:
- A cluster-randomized trial was conducted in 44 upstate New York elementary schools during the 2014-2015 influenza season.
- Schools were randomized to either SLIV or usual care (control), stratified by suburban and urban districts.
- Influenza vaccination receipt was compared between SLIV and control school children using multivariate analyses.
Main Results:
- Children in SLIV schools demonstrated significantly higher influenza vaccination rates compared to control schools (54.1% vs 47.4%, P < .001).
- This increase was observed in both suburban (61.9% vs 53.6%, P < .001) and urban (43.9% vs 39.2%; P < .001) settings.
- Online consent was higher with email notification (four-fifths) compared to backpack fliers (nearly half).
Conclusions:
- School-located influenza vaccination (SLIV) clinics effectively increase influenza vaccination coverage in elementary school populations.
- SLIV is a valuable strategy for improving public health, particularly in diverse settings.
- While SLIV did not substitute for primary care vaccination in suburban areas, some substitution occurred in urban settings.
