Erradicación de la polio

The video discusses the history of polio and the development of vaccines to combat it. Initially, polio caused severe health issues worldwide, leading to early, unsuccessful vaccine attempts. Jona Salk developed a vaccine using inactivated polio virus, which was a breakthrough but faced a major setback due to a manufacturing error by Cater Laboratories, resulting in numerous infections and deaths. Subsequently, Albert Sabin created an oral vaccine using attenuated live virus, which was tested extensively and contributed significantly to the global eradication of polio. The video highlights the importance of these vaccines in medical history.
