The looming superbug crisis: Politics, profit, and Big Pharma

Here's how we stop a health crisis before it wreaks havoc on us.

Videos
  • Alexander Fleming discovered a fungus that produced a chemical that could stop nearly every bacteria in its path.
  • The 1950s are known as the Golden Era of Antibiotic Development. However, today, there is a looming superbug crisis because bacteria has mutated whilst we've focused on treating other diseases, such as cancer and heart disease.
  • Many companies in the pharmaceutical industry don't want to take on the expensive risk of finding another antibiotic drug. However, a potential superbug crisis may compel us to use tax-break and patent policies to incentivize them to do so.
