7. Development of Polio Vaccine (1953) The development of the polio vaccine by Jonas Salk in 1953 was a landmark achievement that nearly eradicated a disease that had once posed a major health crisis. Polio, a highly contagious viral infection that primarily affected children, could cause paralysis and even death. Salk's vaccine, based on inactivated poliovirus, proved to be safe and effective in preventing the disease. The successful implementation of the polio vaccine demonstrated the immense power of vaccination in controlling and preventing infectious diseases. Salk's breakthrough not only saved countless lives but also paved the way for subsequent advancements in vaccine research and inspired the global campaign to eliminate polio altogether.
