Polio vaccination starts in north Gaza despite obstacles

A campaign to vaccinate a final 200,000 children in north Gaza against polio began on Tuesday although health and aid officials said the operation was complicated by access restrictions, evacuation orders and shortages of fuel.

The campaign in north Gaza follows the vaccination of more than 446,000 Palestinian children in central and south Gaza earlier this month.

Vaccination centres are in areas that are militarily very active, difficult to reach and isolated if things go wrong, Sam Rose, a deputy director of Unrwa, told Reuters.

"There are some nerves, but we'll have to make it work," he said.
