A third phase of the polio vaccination campaign is set to begin tomorrow in part of the northern Gaza Strip after being postponed from 23 October 2024 due to lack of access and assured, comprehensive humanitarian pauses, intense bombardment, and mass evacuation orders. These conditions made it impossible for families to safely bring their children for vaccination and to organize campaign activities.
The humanitarian pause necessary to conduct the campaign has been assured; however, the area of the pause has been substantially reduced compared to the first round of vaccination in northern Gaza, conducted in September 2024. It is now limited to just Gaza City. Though in the past few weeks, at least 100 000 people have been forced to evacuate from North Gaza towards Gaza City for safety, around 15 000 children under ten years in towns in North Gaza like Jabalia, Beit Lahiya and Beit Hanoun still remain inaccessible and will be missed during the campaign, compromising its effectiveness. To interrupt poliovirus transmission, at least 90% of all children in every community and neighborhood must be vaccinated. This will be challenging to achieve given the situation.
The final phase of the campaign had aimed to reach an estimated 119 000 children under ten years old in northern Gaza with a second dose of novel oral polio vaccine type 2 (nOPV2). However, achieving this target is now unlikely due to access constraints.
