What is the polio vaccine? Health expert explains its history and success

The article from MSN discusses the history and success of the polio vaccine. Polio, a highly infectious disease that can lead to paralysis, was a major public health concern until the development of effective vaccines. The first breakthrough came with Jonas Salk's inactivated polio vaccine (IPV) in 1955, which used killed poliovirus to immunize individuals without the risk of causing the disease. Following this, Albert Sabin developed the oral polio vaccine (OPV) in the late 1950s, which uses a live attenuated virus, offering easier administration and better intestinal immunity. The vaccines have been instrumental in reducing polio cases by over 99% since their introduction, with the Global Polio Eradication Initiative aiming to completely eradicate the disease. The article highlights the vaccines' role in not only preventing polio but also in demonstrating the power of vaccination in public health, detailing the shift from widespread epidemics to near-eradication, and the ongoing efforts to eliminate the few remaining cases worldwide.
