5 Babylonian Epic of Gilgamesh (2000 B.C.) diseases, pestilence Egypt older dynastiessevere epidemics Pantheon for the god of disease HISTORY OF IMMUNOLOGY 1880 – First World Warstudy of diseases, vaccines 1920 – 1960scientific revolution, chemistry/biology Old TestamentGod’s punishment Phobeus Apollo Plague - Greek army before Troy Immunological memoryThucydides, historian, Athen 430 B.C. pestilence epidemics „yet it was with those who recovered from the disease that the sick and the dying found most compassion……. No fear for themselves; as no man was never attacked twice-never at least fatally” ImmunityImmunitas – exemption from service or duty Depletion theoriesNutrition/factors supporting pathogen growth become limited - even Pasteur Variolation (wild type)smallpox, ancient Chinese method practiced in Europe, too (pustular fluid or dried scabs inoculated) Lady Mary Montague, 1718….

6 Edward Jenner Edward Jenner 1749 – 1823 Immunity (protection) can be induced (cowpox - smallpox) FIRST VACCINATION

7 smallpox –Dread disease, 10% of all death –Infants, children, 20 – 50 % died –Pockmarks, blindness –Survivals – exempt from the disease –Variolationinoculation –Variolation/inoculation 1% mortality UK Cow PoxCow Pox contracted individuals – preventive effect Edward Jenner 1749 – 1823Edward Jenner 1749 – 1823 Training in St. Georges Hospital London 1772 MD,Practice in Gloucestershire, 1772 MD, St. Andrews University, Scotland Publications:Publications: –Jenner,E.(1788).Observationson the natural history of the cuckoo.

9 Koch Laboratory Berlin 1890, Diphteria and Tetanus toxin Emil Behring Shimbasaru Kitasato 1.Many disease occurs only once (natural protection) 2.Some diseases can be prevented by vaccination 3.The blood contains anti-bacterial activity (anti-toxins, serum therapy) 4.worked on antitoxins for tetanus diphtheria and anthrax. HUMORAL IMMUNE RESPONSE Humoral factors Antibodies in serum – bound to relevant pathogens
