Since the 1970s, researchers have engineered superbugs. While this research could help us prepare for future outbreaks, the stakes of this work are extremely high: if even one dangerous virus escaped a lab, it could cause a global pandemic. So, what can we do to minimize risk? And is the knowledge gained even worth the risk in the first place? Dig into the ongoing debate over virology research.

 TED-Ed: What happens if an engineered virus escapes the lab?

What happens if an engineered virus escapes the lab?

Scientists engineer superbugs to preempt pandemics, but a lab leak of such pathogens could ignite a global health crisis.

To mitigate lab risks, experts propose an international database of leaks and robust early warning systems for pandemics.

Engineering viruses to prevent pandemics risks catastrophic leaks, sparking a vehement debate on biosecurity and ethics.
