Citing Pope Francis’ call to “draw near to new forms of . vulnerability,” the Vatican hosted its first-ever event on autism this weekend. The three-day conference, which began Thursday, was organized by a Vatican body focused on health care and in some ways looked like a general secular gathering. Experts from 57 countries updated one another on such issues as genetic research, pain management and government policies toward people with autism. . . . Bob and Suzanne Wright, Catholics and co-founders of the major U.S. advocacy group Autism Speaks, will give a presentation at the conference.
