Brief Summary

Under-immunization rates for childhood immunizations in the United States range from 8-20%. Previous studies have demonstrated that pediatric patients are most likely to be under-immunized for seasonal immunizations. The aim of this study is to explore the factors and facilitators contributing to measles immunization hesitancy. A secondary aim is to explore the impact of hypothetical contexts on measles immunization hesitancy. The results of this study may identify potential disparities in measles immunization coverage and potential solutions for addressing those disparities.

Outcome Measures

Primary Outcomes (1)

• Caregiver Measles Vaccination Intent

  Caregiver intent to vaccinate their child against measles, measured using a single survey item with categorical responses ("yes," "unsure," "probably not," or "definitely not") and reported as the proportion of caregivers classified as intent ("yes") versus non-intent ("unsure," "probably not," or "definitely not") at baseline.

  Baseline (during pediatric emergency department visit)

Secondary Outcomes (1)

• Change in Caregiver Measles Vaccination Intent After Message Exposure

  Immediately after provider message exposure during the same emergency department visit
