Official title

Prospective Study of School-based Influenza Vaccination's Impact on School Populations

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Rates of confirmed influenza illness in vaccinated and non-vaccinated children will be compared between schools with and without vaccination programs. The investigators hypothesize that in addition to lowering rates of influenza in vaccinated children, raising vaccination rates by 30-40% through school-based vaccination programs will decrease incidence of influenza in non-vaccinated children attending those schools compared to non-vaccinated children in schools with low vaccination rates.
