The military wants to stop pandemics. Many of the innovations and breakthroughs deployed to combat COVID-19 began years ago as Pentagon-funded research programs to protect soldiers, some spearheaded by the Defense Advanced Research Projects Agency. Bill Whitaker and 60 Minutes cameras were allowed in to report on some of the technologies the Department of Defense is developing to defend against future pandemics -- including a single vaccine to ward off all coronaviruses. Whitaker's report will be broadcast on 60 Minutes, Sunday, April 11 at 7 p.m. ET/PT on CBS.
