Eradication of Polio

The video discusses the history of polio, a highly contagious virus affecting children worldwide, and the development of vaccines to combat it. Initial vaccine attempts were problematic, but Jonas Salk's dead virus vaccine in the 1950s marked a breakthrough. Despite a major setback with Cutter Laboratories' live virus incident, improvements in manufacturing ensured safety. Albert Sabin later developed an oral vaccine using a weakened virus. Together, these vaccines have nearly eradicated polio globally, showcasing a significant medical success story.
