Every year, 1.5 million kids around the world die as a result of not getting vaccines (疫苗). This is partly because transporting and storing medicines can be a huge challenge in some countries.

Anurudh Ganesan, 17, knows this firsthand. When he was a baby in India, his grandparents carried him 10 miles to a health clinic in a remote village to receive a vaccine. But by the time they arrived, the vaccines were no longer usable because they had been overheated.

Vaccines, Anurudh later learned, must be kept cool to stay effective. But refrigerating them requires electricity or ice – precious resources that many developing countries lack.

Although Anurudh eventually received the vaccine he needed, his experience as a baby and the sad reality that so many other children aren’t as lucky motivated him to take action. The high school student invented Vaxxwagon, a portable vaccine-carrying device that generates its own power to keep lifesaving medicines cool as they’re delivered to remote areas around the world.

Anurudh first got his idea for Vaxxwagon in 2014. He read several textbooks to learn everything he could about refrigeration, and then he did research online to learn more about vaccines. Rather than relying on electricity or ice, Anurudh figured out a way to use wheels to power a refrigeration system for about eight hours. The entire rechargeable cooling system can be pulled to areas in need of vaccines by a bicycle, a car, or an animal. Eventually, Anurudh took his design to professors at Johns Hopkins University for advice. Not only did they confirm Vaxxwagon could work, but they offered him funding to help build it.

Anurudh was rewarded with the 2015 Google Science Fair LEGO Education Builder Award for his invention. Anurudh says his final goal is to start selling Vaxxwagon to relief organizations, so it can be used to help people around the world.

Anurudh, who plans to pursue engineering degree in college, says, “Don’t give up on your ideas. But always try to help others with your projects. That’s the point of engineering – to help people.”
