Did you know on 23 January 1922, the first successful insulin injection was given to a human patient, changing the course of medical history.
Fourteen-year-old Leonard Thompson, who had severe type 1 diabetes, received a purified insulin extract that dramatically improved his condition.
Before insulin, diabetes was considered a death sentence. This breakthrough has since saved and transformed the lives of millions of people worldwide. While treatments continue to advance, there is still no cure for diabetes.
Today, we recognise this milestone and the lasting impact of scientific discovery on global health.
