Healthy, Immunized Communities Study
A Randomized Study to Determine the Efficacy of a Multi-tiered Community- and School-based Approach to Enhance School-aged Children's Recommended Vaccinations.

Detailed Description
Vaccines are considered one of the greatest public health successes. Unfortunately, an increasing rate of parental resistance in recent years has led to a reemergence of vaccine-preventable diseases. This project seeks to determine the effect of a multi-tiered school and community-based approach to improving rates of parental intent to vaccinate for middle school-aged vaccinations including Human Papillomavirus (HPV), meningitis (MCV) and Tetanus, Diphtheria, Pertussis (TDap).
By randomizing participating schools, parents receiving the intervention will participate in (1) a community-based event to raise parental awareness of the importance of vaccination and (2) a social marketing to target parents' attitudes and knowledge around vaccinations.
The Investigators hypothesize that participation in this study will increase parental intention to vaccinate. In addition, this study intends to improve rates of recommended vaccination among middle school-aged children, as measured through vaccine uptake information required for annual entry into Pennsylvania public schools.
The Penn State team brings a breadth of experience in pediatrics, community-engaged research, adolescent health, and engagement with schools.

Intervention / Treatment |
---|---|
No Intervention: Usual Care
Educational emails about broad health topics to keep control group engaged

|
Active Comparator: Multi-Component Intervention
(1) a community event to raise parental awareness of the importance of vaccination; (2) social marketing to target parents' attitudes and knowledge around vaccinations in the form of educational material

Formative focus group data was used to design an educational community event to improve information share and vaccine education/knowledge.
Formative focus group data was used to design educational messaging to be electronically distributed to intervention participants

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Intention by parents to vaccinate school-aged children, as measured by survey
Time Frame: Through study completion, an average of 1 year
|
The change between the pre- and post-intervention proportions will be compared within the study groups as well as between the two groups using a generalized estimating equations (GEE) model that includes factors for time, study group, and the interaction between the time and study group.
Given that there is no specific power calculation for a GEE model, this study will focus on a subcomponent of this analysis for the comparison of the change within the intervention group between pre and post and double the sample size to account for the control group.
The comparison of the change between the pre- and post-intervention proportions could be accomplished with a McNemar's test.
