Societal support for traditional childhood immunization is changing. Increasingly, parents are renegotiating recommended immunization schedules with pediatricians. Marcuse, also associate medical director at Seattle Children's Hospital, discusses this hesitancy and the potential consequences for disease prevention. In this videotaped lecture, he also addresses balancing parental rights with protecting public health. This lecture was part of the Howard A. Schneiderman Memorial Bioethics Lecture Series, which began in 1990 with an endowment from Schneiderman, the third biological sciences school dean. The series brings renowned experts to UCI to speak about the social and ethical implications of advances in biology and medicine.
