Increase Vaccine Uptake in Adolescent in Rural South (INVEST)
November 22, 2022 updated by: Duke University
A Tailored School-based Intervention to INcrease VaccinE Uptake Among adoleScenTs (INVEST) in the Rural South
The benefits of adolescent vaccines are well known for preventing meningococcal infection and human papillomavirus (HPV)-related pre-cancerous lesions.
Yet, many adolescents in the United States (US) remain under-vaccinated, with vaccination rates among rural adolescents significantly lower than among their urban peers.
In addition, there are urban-rural disparities in the coverage of HPV vaccine, particularly in Southern states like North and South Carolina, which currently fall below the Healthy People 2020 goal of ≥80% coverage.
The goal of the proposed study is to evaluate the feasibility and preliminary efficacy of a school-based intervention for increasing vaccine uptake among adolescents in rural North and South Carolina.

Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: INVEST Intervention
|
The intervention will consist of 3 primary components: 1) school nurse training and technical support for promoting adolescent vaccination (Tdap, MenACWY, HPV) and strengthening existing school nursing vaccination programming, 2) caregiver-targeted educational materials that are disseminated via school nurses, and 3) tools and resources to facilitate linkage to vaccination providers in the local community.
Existing materials will be used in the intervention such as resources available from the Centers for Disease Control and Prevention and Middle School Health Starts Here tool kit from the National Association of School Nurses and the National HPV Roundtable.
Technical support includes the study team working with local school nurses to identify educational materials available from national and statewide sources.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in the proportion of adolescents who ever received at least one dose of HPV vaccination in the intervention group after the intervention implementation compared with before intervention implementation
Time Frame: Baseline, 9 months
|
HPV vaccination status (received at least one versus no doses) of middle schoolers (by district) will be obtained from official vaccination records before and after intervention implementation.
|
Baseline, 9 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in the proportion of adolescents who have completed the HPV vaccination series (2 or 3 doses depending on age at vaccination initiation) in the intervention group after implementation compared with before intervention implementation
Time Frame: Baseline, 9 months
|
HPV vaccination status (received at least one versus no doses) of middle schoolers (by district) will be obtained from official vaccination records before and after intervention implementation.
|
Baseline, 9 months
|
Mean score representing fidelity of intervention across intervention schools.
Time Frame: 9 months
|
Score items (0-100%) from a study specific checklist (Fidelity Checklist) will be completed by school nurses from intervention schools with a high score (100%) indicating more adherence to the study intervention and 0% indicating the worse score and less adherence to the study intervention
