202 years ago today, on January 26th, 1823 (December 15th, 1822 in the lunar calendar), Edward Jenner, the founder of vaccinia vaccination, died. Smallpox is gone from our world forever! Thanks to Jenner, salute to the hero of the people! Edward Jenner Nowadays, when mankind has finally eliminated the terrible infectious disease smallpox, we can't help but miss Jenner, the great British doctor, the founder of vaccination. Edward Jenner, the inventor of vaccination, is a British doctor. Edward Jenner was born on May 17, 1749 in the Pastoral District of Berkeley, Gloucestershire, England, to a family of priests. He was 5 years old when the pastor's father died and lived with his brother Stephen Jenner, who was a pastor. Jenner is strong, robust, gentle in nature, and has a wide range of interests, especially nature. He was an excellent student at school and collected specimens of many animals and plants. When Jenner was a teenager, the terrible plague of smallpox was spreading all over Europe, and it was also spread to America by prospectors, explorers and colonists. Almost everyone in Britain can catch this disease, leaving ugly scars on the face or body of adults. Thousands of people become blind or crazy because of their serious illness, and more people die every year. Jenner witnessed this disaster brought to mankind, and from the age of 13, he made the desire to be a doctor to cure this disease in the future. With the help of his brother, Jenna studied medicine with surgeon Ludlow for seven years. By the age of 20, he was already a capable assistant surgeon. In medical practice, Jenner was inspired by the discovery that ranch milkmaids did not contract smallpox after contracting cowpox on cows with cowpox. After more than 20 years of exploration and research, one morning in May, 1796, he used a clean lancet to cut the arms of an 8-year-old child named Jamie several times and inoculated them with cowpox pulp. Facts have proved that this is a correct and effective way to prevent smallpox, and vaccinia vaccine has been produced since then. The success of vaccination has created a broad field for immunology, and Jenner has won great acclaim internationally. In the summer of 1799, people praised him as a great scientific inventor and life saver. Napoleon once called Jenner a great man. All modern inoculation methods actually originated from Jenner's first great discovery. Smallpox was prevalent in Europe in the 18th century and became the main cause of death. (In 1555, there was a smallpox pandemic in Mexico, which killed 2 million of the country's 15 million people. It is estimated that 150 million people died of smallpox in the eighteenth century. George Washington suffered from smallpox in 1751, but it became a pockmark since then. In 1774, King Louis XV of France died of smallpox. Among the ten Qing emperors, Shunzhi and Tongzhi died directly of smallpox. Although Kangxi and Xianfeng were lucky enough to get their lives back from the clutches of smallpox, they left permanent pockmarks on their faces.) As early as Edward Jenner's apprenticeship, Jenner noticed from patients' dictation that people infected with cowpox would not get smallpox again. This is a direct clue to his invention of cowpox. In 1796, he obtained acne pulp from the finger lesion of Sarah Nems, a milkmaid suffering from cowpox, inoculated it into the upper arm of an 8-year-old boy named James Phipp, and then attacked it with smallpox pulp. Phipp was safe and sound. The following year, he vaccinated three more people, all of whom were successful, and submitted the manuscript of the paper to the Royal Society. In 1798, he published a paper entitled "Research on the causes and effects of vaccination against cowpox". In the vaccination trial, peers and church joined forces to besiege Chener. The Royal Society did not believe that an ordinary rural doctor from the backcountry could subdue smallpox. They treated him as a "liar" who seeks fame and sensationalism and refused to accept his writings. Colleagues of the Gloucester Medical Association attacked him for trampling on Hippocrates' Doctor's Oath and wanted to expel him from membership. Because Jenner's vaccinia vaccination method is simple, safe and efficient, it quickly spread to European countries and the American continent in more than ten years. The British government finally recognized the important value of Jenner's discovery, and established a research institution in London-the Royal Jenner Society, chaired by Jenner until his death. On January 26th, 1823, Jenner, the great doctor, stopped his heart beating at his Berkeley apartment for 73 years. In 1980, the United Nations solemnly declared in Nairobi: "Smallpox has become extinct in the world." The significance of vaccination pioneered by Jenner is not only that it eliminated a disease that seriously threatened mankind, but also that it blazed a new path in scientific research in the field of immunology. Jenner is known as the great scientific inventor and the saver of human life. His reputation and achievements were so brilliant that even the mighty Napoleon called him a "great man". From then on, human beings no longer have to be afraid of the tyranny of smallpox, and thousands of mothers in Qian Qian don't have to worry that smallpox will take away their little treasures. Edward Jenner Smallpox Cell Today, when human beings are faced with the threat of serious viral diseases such as AIDS, SARS, influenza A virus, etc., we hope that the second and third Jenner will appear in the world, which will provide a brand-new weapon for human beings to finally defeat all kinds of virus demons.
