Researchers have made a breakthrough in plague vaccine development, creating an experimental strategy that protects mice lacking key immune defenses—offering hope for vulnerable populations who can't receive standard vaccines.

The plague may sound like history, but Yersinia pestis still poses a real threat today, occurring in various parts of the world. With approved vaccine options remaining scarce, scientists are racing to develop better protection. This new approach is particularly significant because it works even when the immune system is compromised, potentially safeguarding people with immunodeficiencies who are usually excluded from traditional vaccination programs.
