Our most rapdily growing collection is in the area of public health. We are pleased to include the foundational course in public health, Public Health 200, as part of this collection. The collection also includes a series of lectures discussing global and local public health issues, plus a talk from the School of Biological Sciences on the growing problem of vaccine hesitancy. Other issues addressed in this collection range from public health in war zones to homelessness in Orange County.
