Attack of the Mutants

Big Picture Science

The omicron variant is surging. More contagious than delta, omicron demonstrates how viruses use mutations to quickly adapt.

Mutations drive evolution, although most don’t do much. But occasionally a mutation improves an organism. Omicron, the latest in a string of variants, is bad for us, but good for the virus.

How mutation of viruses ensures their own survival while threatening ours, and the prospect of a universal vaccine that would protect us against all a viruses’ variants.

Guests:

• Robert Garry – Professor of microbiology and virologist in the Tulane University School of Medicine
• Kevin Saunders – Professor in the Duke University School of Medicine’s Human Vaccine Institute and professor of surgery

Featuring music by Dewey Dellay.
