Yes Luis, I agree that the WHO list should be used as a reference resource in GNU Health.
What about functionality? Some ideas: When opening the patient record, a pop up message occurs in GNU Health for all "patients" < 18 years old. "Do you want to review / amend this patient's routine immunisation record?" If yes then a tabular form could appear with the child's immunisation record to date. If a date had been passed without the record being "ticked as administered" then it might have a red background. Other ideas might be to produce standard reports which would list all patients due to have vaccines on a particular day / week. The child health professional could then contact the family to bring the child into clinic. I think we both agree that this is very important GNU Health functionality and is well worth a significant amount of development time. Regards Andrew
