Nigeria introduces the inactivated polio vaccine into routine immunization programme


In February 2015, Nigeria became the first polio endemic country to introduce the inactivated polio vaccine (IPV) into its routine immunization programme. The Minister of Health, Dr Alhassan Khaliru, described the introduction as “a quantum-leap opportunity for Nigeria in the polio eradication endgame strategy”.

The introduction of IPV into routine immunization programmes is one of the four major objectives of the Global Polio Eradication Initiative (GPEI). In May 2012, the World Health Assembly called on all countries using only the oral polio vaccine (OPV) to introduce at least one dose of IPV into routine immunization schedules by the end of 2015. This is the largest globally coordinated vaccine introduction project in history.
