The FDA granted a new brain cancer treatment that uses the polio virus with "breakthrough status"

The FDA granted a new brain cancer treatment that uses the polio virus with "breakthrough status." This means clinical trials can move more quickly than usual. Scott Pelley and "60 Minutes" have been following the trials at Duke University for two years, tracking several of the study's participants. Dr. David Agus joins "CBS This Morning" from Los Angeles to discuss what's next for the cancer breakthrough.

Correspondent Rita Braver looks at the scientific arsenal brought to combat the epidemic and develop a vaccine, and talks with documentary filmmaker Carl Kurlander ("The Shot Felt 'Round the World"); Dr. Paul Duprex, who is trying to replicate Dr. Jonas Salk’s success in his research for a vaccine for COVID-19; and Joanne Yager, who survived polio as a teenager and now, at 83, runs a support group for polio survivors in Arizona called Polio Epic Tucson.
