Cranky Uncle game combats climate and vaccine misinformation

John Cook, a University of Melbourne academic, created the Cranky Uncle game to combat climate misinformation. The game has been used by tens of thousands worldwide and has now been adapted to combat vaccine misinformation in Africa. The World Health Organization named vaccine hesitancy as a top global health threat. Trials in Kenya, Uganda, and Ghana showed significant shifts in vaccine attitudes. The game teaches players to spot fallacies and has been well-received.
