"But if it becomes obvious that you and the family will never see eye-to-eye on a specific issue, there's no reason not to 'fire' them, providing you follow the steps necessary to avoid charges of abandonment," Marshall explained in the meeting. "Those include providing written notice that you will no longer treat their children and giving them a set time frame -- at least 30 days -- to find another physician."
Dr. Mary Fallat, chair of the Committee of Bioethics of the American Academy of Pediatrics, said doctors should try hard to work with parents, if they refuse to vaccinate, by providing information and trying to come to an agreement about a vaccination schedule.
"If that doesn't work, and the pediatrician feels really strongly that they cannot care for the child -- which is not the norm -- then they need to find another pediatrician who can take care of that child," said Fallat.
In some cases, Fallat said, doctors may feel an ethical concern about families who don't vaccinate their children.
"Ethically, that is a real concern on the part of the pediatrician because there are some diseases that are really disabling," she said. "If a pediatrician says, 'OK, I agree, it's OK for you not to immunize your children' and they do come down with some of these diseases then… it makes the doctor feel like he's partly to blame."
Yet, while in theory, doctors should find another physician who will treat an unvaccinated child, in the real world, it can put families in a difficult spot.
After Echan left her first pediatrician, she said she could not find another doctor who would take her family, once she told them she was unwilling to vaccinate her children.
"I don't know what happened to my older one, I just know that he has autism and he wasn't born with it," said Echan. "So I don't know what to do then, I'm scared."
Dr. Steven Abelowitz, director of the Coastal Kids clinic where Echan was first turned away, says the process of dealing with parents who don't want to be vaccinated is evolving.
