What are the benefits of the polio vaccine?

The polio vaccine, also known as the poliomyelitis vaccine, offers its main benefits in the following aspects: 1. Disease prevention: The polio vaccine effectively prevents poliomyelitis, a disease that may cause severe limb paralysis and even death. After vaccination, the human body develops antibodies against the poliovirus, thereby significantly reducing the risk of infection and illness. 2. Reducing disease impact: Vaccination has significantly reduced the global incidence of poliomyelitis, effectively alleviating the physical, emotional, and economic burdens of the disease on patients and their families. 3. Safety and efficacy: The polio vaccine is safe and effective. It has undergone rigorous scientific evaluation and clinical trials, which have proven its excellent preventive effectiveness. 4. Long-term immunity: The vaccine is usually administered during infancy and provides long-term immune protection, safeguarding children from the threat of poliovirus.
