The second phase of a polio vaccination campaign in Gaza has been postponed due to escalating violence, intense bombardment, and mass displacement in northern Gaza, according to international organizations such as WHO and UNICEF. The campaign was intended to administer a second dose to over 119,000 children but was hindered by unsafe conditions that prevent families from accessing vaccination sites. Meanwhile, the campaign in southern Gaza has successfully reached 91% of its target population. The conflict has severely impacted infrastructure, complicating efforts to halt the polio outbreak, which began after the virus was detected in sewage and paralyzed a child in July. Israel’s defense ministry confirmed the completion of vaccinations in southern Gaza and plans to begin the northern rollout after assessing conditions. WHO emphasizes that at least 90% of children need two doses to effectively curb the virus's spread.
