The development of effective vaccines to prevent paralytic polio was one of the major medical breakthroughs of the 20th century. Two different kinds of vaccine are available, an inactivated (killed) polio vaccine (IPV) and a live attenuated oral polio vaccine (OPV). The presence of neutralizing antibody against polioviruses is considered a reliable correlate of protection against poliomyelitis.
Pneumococcal vaccine had been introduced in 117 countries by the end of 2014, and global coverage was estimated at 31%. Polio is a highly infectious viral disease that can cause irreversible paralysis. In 2014, 86% of infants around the world received 3 doses of polio vaccine.Targeted for global eradication, polio has been stopped in all countries save 3âAfghanistan, Nigeria and Pakistan. Immunization prevents illness, disability and death from vaccine-preventable diseases including cervical cancer, diphtheria, hepatitis B, measles, mumps, pertussis (whooping cough), pneumonia, polio, rotavirus diarrhoea, rubella and tetanus. 2  Global vaccination coverage is generally holding steady.
