The World Health Organization’s announcement of Israel’s commitment to humanitarian pauses for a polio vaccination campaign is a crucial development. Humanitarian pauses can help ensure that medical aid reaches those in need and that critical vaccination efforts are carried out, which is especially important in conflict zones where health services are severely disrupted. The mixed reports of ongoing violence and calm might reflect the challenges of implementing such pauses effectively in a volatile environment.
The emergence of polio in Gaza after such a long period is deeply concerning, especially given the severity of its impact on children. Abdul Rahman’s mother’s plea highlights the urgent need for effective medical intervention and improved living conditions in the camps.

The lack of available treatment and poor sanitary conditions are significant barriers to addressing both the immediate health needs of affected individuals and the broader public health crisis. The WHO’s effort to initiate a polio vaccination campaign is crucial, but it will require substantial support and coordination to overcome the challenges on the ground and ensure that it reaches those who need it most.
The closure of hospitals and the severe fuel shortages in Gaza are significant factors contributing to the low vaccination rates. The ongoing conflict has severely disrupted healthcare services, making it difficult to maintain routine immunizations and respond effectively to outbreaks. This situation underscores the critical need for humanitarian assistance and support to rebuild and sustain healthcare infrastructure in the region.
Humanitarian pauses are designed to allow for safe passage of aid and access to affected populations, which is crucial for addressing public health crises, particularly in complex environments like Gaza. Their implementation can help ensure that vital health services reach those in need and mitigate the impact of crises such as disease outbreaks.
The planned polio vaccination campaign, spanning multiple phases across central, southern, and northern Gaza, represents a significant effort to combat the outbreak. The goal of providing oral polio vaccine drops to over 640,000 children under 10 is ambitious and critical for curbing the spread of the virus.
Achieving at least 90% vaccine coverage is essential for ensuring herd immunity and preventing the international spread of polio. This high coverage rate is necessary to effectively halt transmission and protect both the local population and broader regions from potential outbreaks. The phased approach will help manage the logistical challenges and ensure that the campaign can reach as many children as possible, despite the constraints imposed by the ongoing conflict and infrastructure damage.
The deployment of 2,700 healthcare workers to deliver and administer vaccines is a substantial and coordinated effort. These workers will be crucial in implementing the vaccination campaign efficiently, especially given the challenging conditions in Gaza. Their roles will involve both directly administering the vaccines and ensuring that the campaign reaches the target population despite the logistical and security issues.
The readiness of the WHO and partner agencies, along with the substantial supplies of vaccines and carriers already in Gaza, is a positive sign for the upcoming campaign. With 1.26 million doses already delivered and an additional 400,000 doses on the way, the campaign is well-prepared to reach the targeted number of children.
Peeperkorn’s acknowledgment of the potential need to extend the campaign highlights the complexities of conducting vaccination efforts in a conflict-affected area. Given the challenges such as insecurity, infrastructure damage, and population displacement, the initial three-day period for each zone may prove insufficient.
Maintaining the cold chain for polio vaccines is indeed a critical concern, especially in a conflict zone like Gaza where infrastructure can be severely compromised. Polio vaccines must be kept at specific temperatures to remain effective, so ensuring proper refrigeration throughout the distribution and administration process is crucial.
Dr. Majed Jaber, who works in Gaza’s coastal Al-Mawasi district, an Israeli-designated evacuation zone where tens of thousands of displaced Palestinians have sought shelter, said earlier this week that only about nine health care facilities across Gaza were still able to facilitate cold chain storage. He said there was no refrigeration in the tent camps or at most local medical facilities in the enclave, and that with each new mass displacement under Israeli evacuation orders, it becomes harder for medical professionals to organize care.
The Palestinian Ministry of Health’s strategy to transfer cold chain equipment between regions as the vaccination program progresses is a practical solution to address the refrigeration challenges. This approach helps ensure that vaccines remain at the correct temperatures throughout the campaign, despite the constraints on infrastructure.
