The World Health Organisation (WHO) and the United Nations International Children's Emergency Fund (UNICEF) have launched an emergency polio outbreak response in the Gaza Strip, with a mass vaccination campaign scheduled from 22 to 26 February 2025.

In a joint statement, the two world organisations said that the novel oral polio vaccine type 2 (nOPV2) will be administered to over 591,000 children under 10 years of age to protect them from polio. This campaign follows the recent detection of poliovirus in wastewater samples in Gaza, signaling ongoing circulation in the environment, putting children at risk.
