plague vaccines

Plague vaccines help protect against the plague, a serious bacterial disease caused by Yersinia pestis. These vaccines stimulate the immune system to recognize and fight the bacteria if exposed. There are different types, including killed or subunit vaccines, which contain inactivated bacteria or parts of it. While not widely used today, they can be important for people at high risk, such as researchers or those traveling to endemic areas. Overall, plague vaccines enhance immunity, reducing the severity of infection and preventing outbreaks, and are part of broader efforts to control this historically devastating disease.
