Evaluation of an intervention program to increase immunization compliance among school children

Area of Science:

• Public Health
• Pediatric Medicine
• Immunization Programs

Background:

• State laws mandate student immunization compliance for school enrollment.
• School nurses dedicate significant time to ensuring student vaccination adherence.
• Existing methods for tracking and improving immunization rates can be inefficient.

Purpose of the Study:

• To evaluate the effectiveness of an educational and incentive program on tetanus, diphtheria, and acellular pertussis (Tdap) booster compliance.
• To determine if targeted education and rewards can increase vaccination rates in elementary school children.
• To assess the impact of a novel intervention on public health compliance.

Main Methods:

• An intervention program was implemented in elementary schools.
• Students received education on immune systems, immunizations, and access to healthcare.
• A reward system (lottery for an iPod Shuffle or RipStick) was offered to compliant students.

Main Results:

• The Tdap booster compliance rate increased from 4% to 57% within a 4-week intervention period in 2009.
• The Tdap immunization compliance rate in the preceding year (2008) was 54%.
• The observed increase in compliance was not statistically significant compared to the previous year's rate.

Conclusions:

• The educational and incentive program did not lead to a significant improvement in Tdap booster compliance rates.
• Further research may be needed to identify more effective strategies for increasing student immunization adherence.
• School-based interventions require careful evaluation to ensure measurable public health impact.
