Project Overview +

This intervention seeks to improve adolescent vaccine uptake. The intervention includes:

  1. Reminder / recall systems to alert parents and providers about when vaccine doses are needed
  2. A tailored educational web-based tool to parents to address the barrier of their unique attitudes about vaccines that hinder utilization

Aims +

Aim 1. To determine the baseline utilization levels of, and the clinical and personal characteristics associated with, vaccine utilization for the adolescent platform of vaccines among a defined population in Michigan;

Aim 2. To assess the patient, parent and provider barriers that currently hinder adolescent vaccine utilization in this population;

Aim 3. To develop, implement, and assess a multi-component intervention to improve adolescent vaccination rates within this population;

Aim 4. To develop an adolescent vaccination toolkit that is based on lessons learned from our intervention.

Participants +

640 Parents of adolescents living in Kalamazoo County who are eligible for HPV, Tdap, Flu, and/or MCV-4 vaccines.

Intervention +

The intervention is based on focus group data collected in Year 1. The program includes:

  1. a reminder/recall system to address the barrier of knowing when doses are needed/missed opportunities for vaccination; and
  2. a web-based intervention to provide individually-tailored educational messages to parents to address the barrier of their unique attitudes about vaccines that hinder utilization.

Findings +

Initial findings:

To test the impact of message tailoring on mothers willingness to have their adolescent daughter vaccinated against human papillomavirus (HPV), 76 mothers of adolescents girls ages 11-15 were randomly assigned to receive either an individually-tailored or untailored educational brochure. Receiving the tailored intervention was associated with significant increase in vaccination intention for their daughter within the following year, but not within an immediate or 6-month time frame. Assessment of actual vaccine receipt 3-months after the intervention was delivered showed no differences between groups in the rate of vaccine administration (5% of the daughters were vaccinated in both the control and intervention groups).

HPV Vaccination Intentional Change (Intentional Change = Post - Pre)

If the HPV vaccine was available for your daughter today, how likely would you be to have her vaccinated? Control Group: 2.00; Intervention Group: 1.43

How likely will you be to get the HPV vaccine for your daughter in the next 6 months? Control Group: 1.04; Intervention Group: 1.43

How likely will you be to get the HPV vaccine for your daughter in the next year? Control Group: 1.11*; Intervention Group: 1.95*

AVG Intentional Change: Control Group 1.38: Intervention Group: 1.60
