More than one fifth of pediatricians stopped treating children whose parents refused to have them vaccinated, according to an online survey of doctors in nine U.S. states.
Such denials run counter to recommendations from the American Academy of Pediatrics and should prompt a discussion about how doctors handle the issue, authors of the survey said in a presentation to the 49th Annual Meeting of the Infectious Diseases Society of America in Boston.
“Pediatricians are starting to recognize that having unimmunized patients in their practice puts other patients at risk when they congregate in the waiting room,” said Christopher Harrison, director of the infectious disease research laboratory at Children’s Mercy Hospitals and Clinics in Kansas City, Missouri, in a telephone interview. “They’re conflicted and the data shows this.”
...
Doctors’ practices varied dramatically by state, however. Minnesota doctors, who saw the highest number of families refusing to vaccinate their children, discharged them less than 1 percent of the time. In contrast, Iowa doctors saw the lowest number of families refusing vaccines, but reported discharging them 38 percent of the time, the survey found.

Interesting study (The article linked is rather brief.). The question becomes, what obligation to doctors have to both unvaccinated children and those who may be at risk when an unvaccinated child comes in sick/as a carrier.
