Ancient farmers' secret weapon: How does the cowpox vaccine protect humans from smallpox?
Over the course of history, cowpox vaccine has become an important weapon against small pox. Through this vaccine, we have witnessed a major breakthrough in the history of human health. How these ancient farmers cleverly used this mechanism to protect themselves, let us review this glorious history together.
Vaccinium is an infectious disease caused by the cowpox virus. Symptoms include large blisters on the skin, fever and swollen lymph glands, usually after contact with infected cattle.
Vaccinium and pox belong to the same family of viruses, but the symptoms of cowpox are milder and the infectivity is lower. Since the 18th century, research on this virus has led to the development of vaccine technology. Led by the British physician Edward Jenner, cowpox came to be recognized as the forerunner of the smallpox vaccine.
After vaccination, the patient will produce antibodies and become immune to both cowpox and smallpox.
As early as 1796, Jenner conducted the first experiment on the cowpox vaccine. He inoculated the liquid from the cowpox blister into the skin of an 8-year-old boy, and finally confirmed that cowpox can effectively protect against smallpox. This development lays the foundation for the future of vaccine technology.
The name "vaccination" comes from the Latin "vaccinus", which means "from cows".
Jenner's discovery not only saved countless lives, it also changed the scientific community's attitude toward vaccination. With the success of the vaccine, the WHO declared the disease eradicated in 1980. Vaccinia vaccine replaced early vaccination methods and became the mainstream protection method against small pox.
Vaccine promotion and controversy
As the use of vaccines gradually becomes more popular, some opposition voices have emerged in society. Some have expressed concerns about the spread of animal germs to humans, fearing that such an approach could have unintended consequences. They expressed their dissatisfaction through cartoons and even worried about the growth of calves after vaccination.
Although most people support the cowpox vaccine, there are still some who are skeptical because of their resistance to change.
For vaccinations at the time, cowpox was far safer than earlier riskier vaccination "vaccination". As the protective effect of cowpox was confirmed, more and more people began to trust Jenner's vaccine, which also promoted the further development of vaccine technology.
Global impact of vaccinia vaccine
With the success of the cowpox vaccine, many countries began to follow suit and carry out large-scale vaccination. King Charles IV of Spain even assigned his own doctors to spread the vaccine to the New World. Doctors used a vivid "living chain" to inoculate the vaccine to 22 orphans who had never been vaccinated before to ensure the continuity and effectiveness of the vaccine.
The spread of vaccines has not only saved countless lives, but also provided valuable reference for future public health.
The cowpox vaccine not only caused a craze in the medical community, but also made the British government pay attention to public health and provide financial support for the development of the vaccine. The British Parliament awarded Jenner several awards, demonstrating the great importance of the cowpox vaccine to society.
Conclusion
The success of the cowpox vaccine not only revolutionized the way humans resist small pox, but also promoted the entire vaccinology. To this day, the history of the cowpox vaccine still inspires us, prompting us to reflect on the importance of vaccines in modern society and the future direction of development. What else can we learn from the search for vaccines?
