T cells are a type of white blood cell that can ‘remember’ antigens for decades. Vaccines developed using this new approach may provide more lasting protection.

Current vaccines target the spike protein of SARS-CoV-2. This protein mutates frequently, which could make currently available vaccines less effective.

Researchers in the United States recently investigated the effects of T cells that recognize a different protein in the virus — one that does not mutate as quickly as the spike protein.
