Over 187 000 children under ten years of age were vaccinated with novel oral polio vaccine type 2 (nOPV2) in central Gaza during the first phase of a two-round polio vaccination campaign, conducted between 1–3 September 2024. Vaccination coverage in this phase exceeded the initial estimated target of 157 000 children due to population movement towards central Gaza, and expanded coverage in areas outside the humanitarian pause zone.  

To ensure no child is missed in this area, polio vaccination will continue at four large health facilities in central Gaza over the next few days. Vaccine doses have been supplied to these sites to meet any additional needs. 

“It has been extremely encouraging to see thousands of children being able to access polio vaccines, with the support of their resilient families and courageous health workers, despite the deplorable conditions they have braved over the last 11 months. All parties respected the humanitarian pause and we hope to see this positive momentum continue,” said Dr Richard Peeperkorn, WHO Representative for the occupied Palestinian territory.

The first phase of the campaign was conducted by 513 teams, consisting of over 2180 health and community outreach workers. Vaccination was provided at 143 fixed sites, including hospitals, medical points, primary care centres, camps where displaced people are living, key public gathering spaces such as temporary learning spaces, food and water distribution points, and transit routes leading from central towards northern and southern Gaza. Additionally, mobile teams visited tents and hard to-reach areas to ensure they reached families who were unable to visit fixed sites. The presence of a substantial number of children eligible for vaccination who were unable to reach vaccination sites due to insecurity, necessitated special missions to Al-Maghazi, Al-Bureij and Al-Mussader – areas just outside of the agreed zone for the humanitarian pause.
