When scientists gave mice a special flu-like vaccine called X-31ca, it helped them fight off a common cold virus — but only if their immune system had two specific sensors (TLR3 and TLR7). When those sensors were turned off, the vaccine stopped working, meaning those sensors are essential for the quick, general protection it provides.
