Pneumonic plague vaccine

The pneumonic plague vaccine is designed to protect against the pneumonic form of plague, caused by the bacterium Yersinia pestis. It stimulates the immune system to recognize and fight the bacteria if exposed, reducing the risk of developing severe pneumonia. While not widely used in general populations, it may be administered to people at high risk, such as laboratory workers or military personnel in endemic areas. The vaccine’s effectiveness varies, and it is primarily used as a preventive measure during outbreaks. It is important to note that vaccination is just one part of overall plague prevention, which also includes avoiding exposure to infected animals or fleas.
