India launched the Pulse Polio Immunization (PPI) programme in 1995 to eradicate polio, with a goal of immunizing all children under 5 through multiple doses of oral polio vaccine (OPV). The campaign faced challenges such as infrastructure issues and diverse cultural attitudes, but ultimately achieved success, with the World Health Organization declaring India polio-free in 2014. Key strategies for the campaign included mass immunization days, extensive awareness campaigns, and surveillance of acute flaccid paralysis cases.
