Research shows mRNA vaccine harnesses T-cell power to combat COVID-19 in lungs

Recent research indicates that mRNA vaccines, such as those developed against COVID-19, possess a remarkable ability to harness T-cell power specifically in combating the virus within the lungs. T-cells, a crucial component of the immune system, play a pivotal role in recognizing and eliminating infected cells. The mRNA vaccines, including those by Pfizer-BioNTech and Moderna, instruct cells to produce a spike protein found on the surface of the virus, prompting a robust immune response that involves T-cell activation. This targeted T-cell activity proves crucial in preventing severe respiratory manifestations of COVID-19, as the lungs are a primary site of infection. The findings underscore the multifaceted effectiveness of mRNA vaccines in conferring not only antibody protection but also engaging T-cell immunity, providing a more comprehensive defense against the virus and offering valuable insights for ongoing efforts in vaccine development and public health strategies.
