How does our remarkable immune system retain the ability to defend against viruses previously encountered? While antibodies persist in our blood for only a few short weeks, our bodies retain the cells that make specific, successful antibodies for decades. Researchers have determined the protein signals that keep the memory of old viruses alive, findings that may aid in creating better, more effective vaccines.
