Shane Crotty, professor at the La Jolla Institute for Immunology, studies how the immune system remembers infections and vaccines.

She explained: “Your immunes system is complicated, and doesn’t just have one weapon.

B and T cells are special white blood cells that work together to hunt down infections and remember how to fight them off, for the future.
