Dr. Bob Sears, a pediatrician in Capistrano Beach, Calif., says that he strongly believes in the protective power of vaccines to save lives. But he's also well-known in Southern California as a doctor who won't pressure parents who refuse to vaccinate their children, or who refuse some vaccines, or who want to stray from the recommended schedule of vaccinations. "They all come to me because, I guess, I'm more respectful of their decisions, more willing to listen to them," Sears says, "[and to] discuss pros and cons and acknowledge that there are some side effects to vaccines."
