Vaccines for Infectious Disease

The technologies that have emerged over the last year or two are incredibly exciting and have incredible potential. The ability to exploit them through, as you point out, mucosal or other strategies of emnization or in combination is very exciting. There might well be more pandemics following this rather large one. So i'm also optimistic that we're going to learn more about developing vaccines for some of the world's big infectious disease killers from what we've done with covid.
