As a member of the human race (albeit sometimes reluctantly) for more than 50 years and a practicing pediatrician for more than 20 of those years, I still do not understand why some issues remain unsolved.
When I began practicing I expected my patients' parents to show up for well-child visits and accept immunizations. Most did without a problem. A few required several reminders, and a very few had to be confronted with the fact that I did not care for unimmunized children. My immunization percentage is very close to 100% and I have "lost" only 2 patients over this issue in 20 years.
