The impact of school-located influenza vaccination programs on student absenteeism: a review of the U.S. literature.

A literature review was conducted to summarize the impact of school-located influenza vaccination (SLIV) programs on school absenteeism. Seven studies were identified: six peer-reviewed articles and one conference presentation. The number of students vaccinated ranged from 185 to 5,315, representing 35-86% of enrolled students. Six studies compared absenteeism for students in SLIV schools and control schools; all found absenteeism decreased in SLIV schools. Three studies compared absenteeism for vaccinated and unvaccinated students in SLIV schools; all found that absenteeism was reduced for vaccinated students. Benefits were also reported to extend beyond the vaccinated children; one study found that absenteeism was significantly reduced among high school students when elementary school students were vaccinated. The available evidence indicates that SLIV programs reduce student absenteeism during the influenza season. Additional research into sustainable funding sources and the comprehensive effects of SLIV programs on students, families, staff, and the community is warranted.
