What is the purpose of the polio vaccine?

Polio vaccine is used to prevent poliomyelitis, also known as infantile paralysis. This is an acute infectious disease caused by the poliovirus, which primarily affects children and can lead to muscle weakness, and in severe cases, may result in permanent limb paralysis, especially in the lower limbs. The use of vaccines has significantly reduced the global incidence of poliomyelitis, and some countries and regions have successfully achieved a polio-free status. Administration of the polio vaccine is an essential component of the immunization program recommended by the World Health Organization (WHO). It typically includes both oral and injectable vaccines, providing protection for children against viral infection and transmission.
