Health authorities begin large-scale polio vaccinations in war-ravaged Gaza

Palestinian health authorities and United Nations agencies on Sunday began a large-scale campaign of vaccinations against polio in the Gaza Strip, hoping to prevent an outbreak in the territory that has been ravaged by the ongoing Israel-Hamas war.

Authorities plan to vaccinate children in central Gaza until Wednesday before moving on to the more devastated northern and southern parts of the strip. The campaign began with a small number of vaccinations on Saturday and aims to reach about 640,000 children.

Israel has agreed to limited pauses in fighting to facilitate the campaign, according to the World Health Organization.

Hospitals in Deir al-Balah and Nuseirat confirmed that the campaign had begun on Sunday.

The campaign comes after the first polio case was reported in Gaza in 25 years — a 10-month-old boy, now paralyzed in the leg. The World Health Organization says the presence of a paralysis case indicates there could be hundreds more who have been infected but aren’t showing symptoms.

Most people who have polio do not experience symptoms, and those who do usually recover in a week or so. But there is no cure, and when polio causes paralysis it is usually permanent. If the paralysis affects breathing muscles, the disease can be fatal.

The vaccination campaign faces a host of challenges, from ongoing fighting to devastated roads and hospitals. Around 90% of Gaza’s population of 2.3 million people have been displaced within the besieged territory, with hundreds of thousands crammed into squalid tent camps.

WHO said Thursday that it has reached an agreement with Israel for limited pauses in the fighting to allow for the vaccination campaign to take place. Israel said Saturday that the vaccination program would continue through Sept. 9 and last eight hours a day.
