More than 1.6 million doses of the polio vaccine have been released for use in Gaza, aimed at preventing a larger outbreak after the virus was found in the region. Steve, how will these doses be allocated? There's been a very detailed plan To have two campaigns that would Vaccinate all children under ten years of age. They’re thought to be the most vulnerable, and they need to be vaccinated twice. And in order to carry that out, you need about 2,700 trained health workers, you need cold chains, and most importantly here, you need a pause in the fighting. So that these 2,700 workers, who are going to set up over 700 different sites, can safely do that.
