Vaccine study aims to unlock secrets of Long-Term immunity

This study looked at how the hepatitis B vaccine triggers the body's immune system, specifically focusing on memory B cells that help provide long-lasting protection. Healthy volunteers who had never been vaccinated against hepatitis B received the vaccine, and researchers analyzed samples from lymph nodes to understand how these memory cells respond to booster doses. The goal was to learn how to design better vaccines for fast-changing viruses like flu and HIV.
