The surprising future of vaccine technology

We owe a lot to vaccines and the scientists that develop them. But we've only just touched the surface of what vaccines can do.

  • "Vaccines are the best thing science has ever given us," says Larry Brilliant, founding president and acting chairman of Skoll Global Threats. From smallpox, to Ebola, to polio, scientists have successful fought viruses and saved millions of lives. So what's next?
  • As Covaxx (formerly United Neuroscience) cofounder Lou Reese explains in this video, the issue with vaccines is that they don't work against "non-external threats." This is a problem, especially now when internal threats (things that cause cancers, Alzheimer's, diabetes, and other chronic illnesses) are killing people more than external threats like viruses.
  • The future of vaccine tech, which scientists are already working toward today, is developing safe vaccines to eradicate these destructive internal agents without harming our bodies in the process.
