Background: For most patients, vaccines are safe and effective, yet there are ~85,000 cases/year of vaccine-preventable disease. Vaccine hesitancy has not been a high-profile issue in the midwest. Our objective was to explore midwestern American Academy of Pediatrics (AAP) members’ perspectives on parental vaccine hesitancy/refusal.

Methods: With cooperation from the state chapters of 9 midwestern states in District VI of the American Academy of Pediatrics, participants were recruited via email and prompted to complete an on-line survey. We used a weighted rank to score ordinal responses. The protocol was given exempt status by Children’s Mercy Hospital’s IRB.

Results: There were 909 responders. Demographics were available for 772:  88 % White, 6% Asian, 2% Black and 4% other; 3 % self-identified as Hispanic/Latino; 58 % female; 59% fell within the 35-54 age range.  Complete or near-complete responses were available for 695 participants. Overall the 3 vaccines that parents most often refuse or defer per responder reports were: 1. MMR, 2. HPV and 3. influenza. The most frequent reasons given were fear of autism, too many shots, and serious side effects. Engaging family in discussion/ presenting options was the number 1 intervention reported across all states at 95%. 66% of responders referred families to websites and 63% used evidenced-based literature.  Only 1% of responders reported using no intervention with hesitant/refusing families.  Practitioners reported seeing anywhere from 1% to greater than 50% of parents delaying or altering the recommended vaccine schedule, and 0% up to 40% of parents refusing at least some vaccines. The majority in all states still report < 5% overall vaccine refusal and < 20% vaccine schedule alteration, although some individuals report much higher rates. Overall, 21% of practitioners reported discharging families from their practice for continued refusal of all vaccines, with Minnesota lowest at 0.9% and Iowa highest at 38%.

Conclusion: Midwest providers have variable attitudes and experience with vaccine hesitancy/refusal. The insights gained from this pilot survey will help design a more definitive survey as well as assist in the design of educational or interventional strategies for practitioners.
