School-based influenza immunization.

Area of Science:

• Public Health
• Epidemiology
• Vaccinology

Background:

• Annual influenza vaccination is crucial for individual and community protection.
• Schoolchildren are a key demographic for influenza transmission but are challenging to reach via traditional methods.
• School-based immunization programs may be necessary to achieve high vaccination coverage in this population.

Purpose of the Study:

• To evaluate the feasibility and effectiveness of a school-based live, attenuated influenza vaccine program.
• To determine vaccination coverage rates achieved in schoolchildren through a school-based initiative.
• To assess the administrative costs associated with delivering influenza vaccine in schools.

Main Methods:

• A free live, attenuated influenza vaccine was offered to all healthy schoolchildren (Kindergarten through 12th grade) in three Minnesota counties.
• Vaccination coverage was calculated based on the percentage of enrolled students who received the vaccine.
• Administrative costs per dose delivered were recorded.

Main Results:

• Vaccination coverage varied by county, ranging from 33% to 58% of students.
• Overall, 41% of enrolled schoolchildren were vaccinated.
• Elementary students achieved higher vaccination rates compared to older students.
• Average administrative costs were $9.78 per dose delivered.

Conclusions:

• School-based influenza vaccination programs demonstrate the potential to achieve substantial vaccination coverage among schoolchildren.
• These programs can be implemented at a modest cost, making them a viable strategy for improving public health.
• Targeting elementary students may be more effective for maximizing initial uptake in school-based vaccination efforts.
