UN agencies to vaccinate 640,000 children against polio in Gaza

UN agencies and local health officials in the Gaza Strip are launching an ambitious campaign to vaccinate 640,000 children against polio.
The rollout relies on a series of localized pauses in fighting between Israeli forces and Hamas fighters, with the first window set to begin on Sunday.
To be effective, the World Health Organization (WHO) says at least 90% of children under 10 must be immunised in a short time frame.
It follows the discovery of the first confirmed case of polio in 25 years in Gaza, with a UN expert saying more children are likely to be infected and that there could be a wider regional outbreak if the virus is not dealt with.
