Hi, and welcome to COVID quickly, a scientific American podcast series.

This is your fast track update on the COVID pandemic. We bring you up to speed on the science behind the most urgent questions about the virus and the disease. We demystify the research

and help you understand

what it really means. I'm Tanya Lewis. I'm Josh Fishman. And we're scientific American's senior

health editors. Today we're going to talk about how COVID has driven a notable decline in

U.S. life expectancy. And some new monoclonal antibodies that could protect us from variants.

People in the U.S. have been living longer and longer during most of the past century.

Then COVID hit, and all of a sudden we're going backwards.

Why are we losing years of our lives?

Life expectancy has only declined a few times in recent memory, during the 1918 pandemic,

during World War II, and during the HIV-AIDS crisis.
