I was once contacted as a pediatric health care provider about a patient who was being followed by CYS in Philly. I told them that they should worry less about that kid and worry more about his younger sibling who hadn’t had any immunizations since they were 2 months old and had never gone to school, even though they were 8 years old. CYS didn’t even know the sibling existed (which I thought was really strange because I saw them both as patients and the parents brought them in together).
