Edward Jenner contribution to microbiology I Father of Immunology

Hello friends today in this video we are going to discuss about the scientist Edward Jenner and his contribution to microbiology as well as immunology. So the first thing is he for his contribution he is known as the father of immunology. Okay so now let's discuss about his all contributions to immunology and as well as microbiology. So he was the first person who successfully introduced vaccination to prevent smallpox. So he invented the vaccination process first time okay so the term vaccine and vaccination are derived from variola vaccini that is the cowpox virus and the term devised by Jenner to denote cowpox because the Latin word for cow is vacca. So for this he termed the vaccine and vaccination to derive the cowpox virus okay. So the next thing is the cowpox virus and the smallpox virus are closely related to each other but the cowpox virus is relatively harmless to humans but the smallpox virus is harmful to humans okay. So now let's discuss about the vaccination search for vaccination. So Jenner first time found that a person who had suffered an attack of cowpox could could not take the smallpox that means a person who had suffered an attack of cowpox could not take the smallpox that means could not become infected by smallpox. So what is the reason? So he found that the cowpox virus that is the relatively harmless virus when infected and human that human raise some induced immunity to fight against cowpox as well as smallpox because smallpox and cowpox both are closely related. So the human raise induced immunity to fight against cowpox as well as smallpox. So after that later when that human attacked by smallpox they are immune because because of the previously inoculation of cowpox previously attacked by cowpox they raised immunity. So after that when they are attacked by the by any smallpox virus they got immune to smallpox virus and do not show any disease symptoms of smallpox virus. So he found Jenner found this thing and interested to make interested to make vaccination vaccination process interested to induce or start vaccination process. So how he start this vaccination process. So 17 in 1796 Jenner found a young dairymaid dairymaid means a who who collect milk from cows. Okay. So he found a young dairymaid Sarah Nils who had fresh cowpox lesions on her hand. So after that using matter from Sarah's lesions of cowpox he inoculated an eight-year-old boy James Phipps who had never had smallpox. Okay. And Phipps become slightly ill over the course of next nine days but was well on 10th day. Okay. And after that Jenner inoculated inoculated the boy Jenner inoculated the boy again with the but this time with the smallpox matter but no disease developed because he was immune. So what is the reason behind all this experiment. So he found that so he Jenner found that the cowpox virus when infected that milkmaid or dairymaid. So from this dairymaid the matter of cowpox lesions transferred into the little boy. So the little boy James Phipps he transferred the cowpox lesions from the milkmaid to the little boy and this little boy raised immunity against this cowpox virus as well as smallpox virus because both are closely related. So when the little boy little boy inoculated with this matter of cowpox lesions he raised immunity against the smallpox virus as well as cowpox virus. So after that when any smallpox virus so after that when Jenner inoculate smallpox virus into that little boy so little that little boy show just a illness just a little illness but didn't show any symptoms of smallpox. So he he was immune to the smallpox. So in this way he started vaccination against viruses okay. So this is his huge contribution to human and in 1798 Jenner having added further cases published privately a book entitled and inquiry into the causes and effects of variola vaccini that is known as the cowpox virus in which he described the protective effect of cowpox against smallpox okay. So this is the all contribution of Jenner Edward Jenner okay to my immunology. Okay so thank you for watching this video.
