**Intact Gift Giving Condition book**

It is replete with scientific background and references but unlike some academic textbooks, the language is plain, simple, and accessible. The Purple Book is unique. It is complete in terms of authoritative recommendations, but it expands upon the official publications of professional societies and governmental agencies by including, in one place, information on such things as how vaccines are developed, tested, and licensed; how vaccine policy is made; what constitutes the vaccine safety net; the legal obligations binding on vaccine providers; billing; and office logistics. The Purple Book is ideal for pediatricians, family physicians, internists, obstetrician/gynecologists, nurses, nurse practitioners, physician's assistants, clinic staff, students, and residents.
