The study, which was conducted by researchers from Washington University in St. Louis and published in the journal  Nature, found that people who were fully vaccinated still had a robust immune response nearly four months later. The researchers were looking at the germinal center, a specialized structure that forms in the lymph nodes following infection or vaccination. The structure trains B cells to fight off infections and possible variants. Typically, the germinal center slows down several weeks after vaccination, but the researchers found that 15 weeks later, the structure was still highly active.
