🧪 The world's first effective oral vaccine against cholera was developed by Swede Jan Holmgren, professor of microbiology at the University of Gothenburg. His discoveries have saved many lives around the world, especially among children. 🌍 Holmgren’s research began in the 1970s and laid the foundations of the Dukoral vaccine, which was first used in the early 1990s.

Jan Holmgren has received many awards for his discoveries. ...
