The second phase of a two-round campaign to vaccinate over half a million young children in Gaza against polio began in Khan Younis on Thursday, the UN agency that assists Palestine refugees, UNRWA, said in a post on the social media platform X, formerly Twitter.
The campaign moved to southern areas of the Gaza Strip following the successful completion of the first phase in the centre of the enclave, thanks largely to pauses in the fighting.
Over the next four days, health workers will target an estimated 340,000 children below the age of 10, with some 517 teams deployed, including 384 mobile teams, according to the World Health Organization (WHO).
A third and final phase will be implemented in northern Gaza from 9 to 11 September, targeting around 150,000 boys and girls.
An urgent response
The overall campaign aims to provide two drops of the novel oral polio vaccine type 2 to more than 640,000 children under the age of 10 during each round.
It is part of an urgent response to prevent the spread of polio, which has resurfaced in Gaza after 25 years following the detection of circulating variant poliovirus type 2 (cVDPV2) in six environmental samples collected from the central area of the Strip in June.
The campaign is being conducted by the Palestinian Ministry of Health in collaboration with WHO, UNRWA, the UN Children's Fund (UNICEF), and other humanitarian partners.
Humanitarian pause respected
During the first phase, from 1 to 3 September, health workers reached over 187,000 youngsters in central Gaza, exceeding the initial estimated target of 157,000.
Vaccinations will continue over the next few days at four large health facilities to ensure no child is missed in the area.
"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.
Reaching families where they are
The first phase of the campaign was conducted by 513 teams, consisting of over 2,180 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 the centre towards northern and southern Gaza.
Mobile teams also visited tents and hard to-reach areas to access families unable to visit fixed sites.
WHO said 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 three areas - Al-Maghazi, Al-Bureij and Al-Mussader - just outside of the agreed zone for the humanitarian pause.
