The 1918 Pandemic: The Deadliest Flu in History

The video discusses the history and impact of the 1918 influenza pandemic, known as the Spanish flu, which killed millions globally. It explores the virus's origins, spread, and the reasons for its high mortality rate, particularly among young adults. The video explains the concept of antigenic shift and how immune responses can vary based on initial flu exposure. It also highlights ongoing efforts to develop a universal flu vaccine to prevent future pandemics.
