The Immunology in Focus videotapes are designed to help the teacher explain the key concepts of basic immunology to an audience whose training entails a significant exposure to the subject. These tapes are essential for preclinical students in medical, dental and veterinary schools and university or college students studying life sciences. Nurses, pharmacists, laboratory technicians, family practitioners attending update courses, graduate medical centers providing continuing education, and industrial and pharmaceutical companies will also benefit. This handbook provides a thorough guide to these videotapes.
