A new study finds more than a third of U.S. pediatricians surveyed say they would tell families who refuse all vaccinations for their children to look elsewhere for care.

The report says that, "In the case of parents refusing specific vaccines, 82 (28 percent of the doctors) said that they would ask the family to seek care elsewhere; for refusal of all vaccines, 116 (39 percent) of pediatricians said they would refer the family" to another doctor.

The reason physicians cite most often for wanting to drop such patients were lack of shared goals and lack of trust. the results of the survey are published in the October issue of the Archives of Pediatrics & Adolescent Medicine.

The study says the rate of unvaccinated children in the United States has risen significantly since 1995. While most parents continue to believe that vaccination is important, a large number express concern about safety.
