The World Health Organization has announced plans to send 1.2 million polio vaccine doses to Gaza amid fears of a polio outbreak after the virus was detected in wastewater. Over the past 10 months, Israel has destroyed all of Gaza’s wastewater treatment plants and most of Gaza’s sewage pumps. The WHO says it is aiming to vaccinate 600,000 Palestinian children under the age of 8. The WHO repeated its call for a ceasefire, saying its medical staff need “absolute freedom of movement” to administer the vaccines.
