Despite the well-known individual and societal benefits of childhood immunization programs and the demonstrated safety of vaccines, many parents are hesitant to have their children vaccinated. Vaccine hesitancy is more than a simple delay or refusal of vaccination. Rather, it can be characterized as a state of mind regarding immunization marked by uncertainty, indecision, conflict, or opposition, and it is best understood as a complex phenomenon with deep sociocultural and psychological roots. The authors developed a laboratory in which communication could be studied in a codified and controlled environment, using standardized patients portraying vaccine-hesitant parents, video-recording, assessment by blinded raters, and a pseudorandomized assignment of pediatric residents to AIMS or standard of care training.
