What Next: TBD

Can We Really Make a Safe Vaccine in 18 Months?

How fast is too fast when it comes to finding the fix for COVID-19?


Episode Notes

There are over 60 vaccines for the coronavirus currently in development. Four of them are already being tested in humans. As researchers move at breakneck speed to find a vaccine, they’re debating breaking (or at least bending) the rules that ensure the end product is safe.

How do we balance speed with safety in the rush to develop a vaccine?

Guest: Dr. Timothy Lahey, an infectious diseases doctor, ethicist, and vaccine researcher at the University of Vermont Medical Center.
