Delivering vaccines directly to the lungs can boost immune responses to respiratory infections or lung cancer, study finds.

Many viruses infect their hosts through mucosal surfaces such as the lining of the respiratory tract. MIT researchers have now developed a vaccination strategy that can create an army of T cells that are ready and waiting at those surfaces, offering a quicker response to viral invaders.

The researchers showed that they could induce a strong memory T cell response in the lungs of mice by giving them a vaccine ...
