Where the risk of polio is low, countries only recommend the IPV, as the risk of vaccine-associated paralytic polio from OPV outweighs the benefits of immunity.\n- Many countries have moved from OPV-only schedules to using IPV alongside or instead of OPV, following the global phased withdrawal of oral polio vaccines as part of the polio eradication endgame.\n- Data is based on the most recent national immunization schedule reported by each country through the WHO/UNICEF Joint Reporting Form on Immunization.", "dimensions": {"years": {"values": [{"id": 2025}, {"id": 2024}, {"id": 2019},
