Inventing the second malaria vaccine with Katharine Collins

Hard Drugs
Dela

Malaria is caused not by a virus or bacterium, but by a complex, shape-shifting parasite that has evolved alongside us for millennia. This has made vaccine development a brutal challenge.

In this episode, Jacob and Saloni are joined by Katharine Collins, who co-invented the second malaria vaccine, called R21, during her PhD. They discuss the gruelling process of reverse-engineering a vaccine and eureka moments along the way. They ask whether the biggest barriers to new vaccines are scientific or financial, and what it will take to finally eradicate one of natureʼs most vicious killers.

Hard Drugs is a podcast from Works in Progress about medical innovation presented by Saloni Dattani and Jacob Trefethen.
