A quick Q&A: How to make a variant-proof vaccine

Viruses mutate — that’s just what they do. Unfortunately, it’s tricky for vaccine-makers to keep up with the changes. That’s why some researchers are looking into making a different kind of vaccine that would be virtually variant-proof, as Emily Mullin reports on the Blog. Rather than designing a vaccine that relies on antibodies, they are tapping into another branch of the immune system: T cells. Unlike antibodies, which attack virus particles before they enter cells, T cells can destroy cells that are already infected.
