Why did Edward Senna use vaccinia to prevent smallpox?
Smallpox is a serious infectious disease caused by smallpox virus and the most harmful disease in human history. /kloc-in Europe in the 0 th and 8 th centuries, the spread of smallpox was difficult to contain, and vaccination with human pox was not safe at that time. Qin Na accidentally discovered that during the period when smallpox was rampant, milkmaids were often safe, and most of them had acne, which was infected when cows were milking when they were born with vaccinia. So he began to study the prevention of smallpox with vaccinia and imagined the possibility of vaccinating people with vaccinia.
