Jenner is a rural doctor in the United Kingdom in the 18th century. He has been thinking about confrontation in the face of the serious consequences of the smallpox epidemic. At the time, human acne was the leading technology invention, which was highly valued by various countries. It was spread to Russia, North Korea, Japan and other countries, and it was transferred to Turkey, Europe, Africa and other countries through Russia. In the 18th century, at the time, the British ambassador of Constantinople, Montagu, in Turkey, learned about the Chinese vaccination through Russia and introduced the technology to the United Kingdom. Since then, the vaccination of human pox invented by the Chinese has spread in the UK and has been improved. British doctor Jenner heard that female workers who squeezed milk, once they had vaccinated, would not have to be afraid to encounter the epidemic. This strange phenomenon has greatly inspired him. From 1788 to 1796, Jenner worked on the observation and experimentation of vaccinia. On May 14, 1796, he took a small amount of pus from a cowpox on the back of a milking woman's hand and inoculated it on a child. Two months later, he inoculated the child with variola virus, and the child did not have symptoms of smallpox. This success has enabled Jenner to increase his determination to inoculate vaccinia. In 1798, he published the famous paper "Research on the causes and results of vaccinia", and the vaccination method was officially born. Before Jenner, some people tried to breed vaccinia, but failed to make scientific experiments. In 1799, Jenner made a nationwide survey on the prevention of smallpox to prevent smallpox, and the results confirmed his theory. Jenner devoted most of his life to the study of vaccinia, and the British Parliament awarded him £20,000 to support his research. After Jenner's death, London, England, made a statue for him, so that people will always remember this great and ordinary doctor.
Since Jenner invented the vaccination against vaccinia in 1798, humans have been vaccinated for nearly 200 years, but so far, there is no special way to treat smallpox. Vaccination against smallpox is to prevent and control smallpox. A simple and effective measure that is raging.
In 1805, the Portuguese-born He Weite introduced the vaccination method to China. The ship doctor Pearson of the East India Company also introduced the vaccination method to China. Because vaccinia was often free in China at the time, and the vaccination method was safer than the acne method, more and more Chinese people accepted vaccinia. Vaccinia replaces human pox.
In the late 1970s, humans completely controlled smallpox on Earth. The World Health Organization (WHO) announced this result in 1980 and stopped widespread vaccination worldwide. Stopping vaccination for more than 20 years, no case of smallpox was found in the world.
Since the Jin Dynasty, China has recorded the smallpox and began to explore prevention methods. In the middle of the 16th century, China and Georgia independently invented the vaccination of human vaccination, opening up a new way of artificial immunity, and human acne was quickly spread all over the world. At the end of the 18th century, Jenner of the United Kingdom invented vaccinia on the basis of Chinese and Georgian acne: in the early 19th century, vaccinia was transmitted back to China. In the 1970s, the smallpox that had long ravaged the world was completely wiped out by humans.
