Is the refusal to care in relation to a parent not wanting their child to be vaccinated, or solely due to not having been the primary care provider since birth?

Is the refusal to care in relation to a parent not wanting their child to be vaccinated, or solely due to not having been the primary care provider since birth? Edit: I guess my reasoning for this question is based on new guidance from the American Academy of Pediatricians regarding refusal of care to those who refuse childhood immunization. I can't say I agree with that sentiment, and I would also argue that the majority of pediatricians in the US do not refuse care to families who refuse immunization. Why? Because it makes far more sense for a physician to continue to follow up with patients to continue recommending they get immunized. I assure you that most doctors, including pediatricians, don't want kids to die, so most don't refuse care just cause of a family not wanting to vaccinate their kid. It's unfair to a kid that likely doesn't have the competence or capacity to make decisions for themselves. I can't speak towards any pediatrician refusing care, or their reasoning, because I literally have not met one that does. Edit 2: here is some explanation from the AAP as to when they would recommend dismissal of a family. Note that they specifically note that dismissal should be "a very last resort".
