In the past 20 years alone, three coronaviruses have caused major human disease outbreaks.

First came the original SARS virus in 2002, then Middle East Respiratory Syndrome in 2012, and in 2019,

SARS-CoV-2 emerged, setting off a global pandemic. Hundreds more coronaviruses are lurking in

bats and other animals. Scientists have warned that some of these viruses could emerge in the future to infect

people. Our current COVID-19 vaccines were specifically designed for SARS-CoV-2. But what if a next-generation

vaccine could protect against both known and unknown coronaviruses? Scientists at the Walter Reed Army Institute of Research in

Silver Spring, Maryland are working on a so-called universal coronavirus vaccine. Dr. Kavan-Majarid is

leading the effort. We've developed a vaccine specifically for SARS-CoV-2, but what we've seen in our animal studies

is that the immune response that it induces is active against all the variants, as well as

other coronaviruses like SARS-CoV-1 that was seen back in 2002.

Before COVID-19, Majerod and his army colleague Gordon Joyce were trying to develop a

universal vaccine against a different group of viruses, one that includes Lassa virus,

which is similar to Ebola.

And so when the new coronavirus was identified as a coronavirus and the sequence was published,

January 10th of 2020, that night, Dr. Joyce and I had a late night conversation about turning
