BREAKING: A massive polio vaccine campaign targeting some 640,000 Gaza children is now set to begin on Sunday, 1 September, with agreement by Israel for a three-day humanitarian pause in fighting, a senior WHO official said on Thursday. A second round of the campaign for the two dose vaccine is planned three weeks later.

Distribution complicated by evacuation orders
Tens of thousands of Palestinians have been ordered move once again from parts of the central Gaza city of Deir al Balah as well as sections of Khan Younis in the south. The areas were among those previously designated by the Israeli army as humanitarian zones for the more than 1.2 million Gazans who have been internally displaced during the grinding war between Israel and the Palestinian Hamas.
“Mass evacuation orders are the latest in a long list of unbearable threats to UN and humanitarian personnel,” Under-Secretary-General Gilles Michaud said in a statement on Tuesday.
“The timing could hardly be worse,” he added, referring to the polio vaccination programme that was about to start.
Poliovirus was first detected in Gaza in late June by the Global Polio Laboratory Network. The virus was confirmed in six sewage samples from Khan Younis and Deir al Balah, cities in the south and centre of the 365 square kilometer Gaza Strip.
In mid-August, three suspected polio cases in children were identified, Health Policy Watch reported, followed by the confirmation of one case in a 10-month old infant last week. As nine out of 10 polio cases are generally asymptomatic, the spread of the virus is likely far wider than reported cases.
In response, WHO, UNICEF and UN Relief and Works Agency for Palestine Refugees (UNRWA) organised a vaccination campaign targeting over 640,000 children.
Delaying the vaccinations would have serious consequences, Dr Hamid Jafari, the director of the WHO’s polio eradication programme in the Eastern Mediterranean warned on 23 August.
“The risk of this virus spreading into Israel, into the West Bank and into surrounding countries like Lebanon, Syria, Egypt and Jordan is high. So we need to act fast.”
Humanitarian pauses
To reach the intended vaccination target and gain better population immunity, WHO and other UN agencies had appealed for at least two humanitarian pauses of seven days to deliver the vaccine doses.
The pause in the grinding 11 month Israel-Hamas war is necessary to ensure a cold chain of the vaccines, as well as to guarantee the safety of patients reaching healthcare points and the right timing of the second dose, officials have stressed.
The operation in a conflict zone will be complex, and its outcomes will depend on the conditions on the ground, Sam Rose, Senior Deputy Field Director for UNRWA in Gaza stressed in a statement Monday.
UN agencies and partners “stand ready to vaccinate children, but need a humanitarian pause. We and the rest of the system involved will do our absolute utmost to deliver the campaign,” Rose said, “because without it, the conditions will be much worse sadly.”
Overcrowding
Polio is a highly infectious viral disease largely affecting children younger than five years of age. It spreads between humans by a fecal-oral route or, in the minority of cases, through contaminated water or food.
One in 200 infections causes permanent paralysis and, in 2-10% of the paralysed, death. While there is no known cure for polio, the disease was mostly eradicated in the World Health Assembly-initiated Global Polio Eradication Initiative starting 1988.
In some cases, the weakened virus present in the oral polio vaccine (OPV) can mutate and spread in communities not fully vaccinated against polio, especially in poor hygienic conditions or in overcrowded areas. The longer it is allowed to circulate, the higher the chance for further mutations, creating concerns about a large-scale outbreak.
