Ummmm....there's been only one case, and both Israel and Hamas have agreed to a "time-out" to allow for mass vaccinations.
https://www.timesofisrael.com/israel-agrees-to-pinpoint-humanitarian-pauses-in-gaza-for-polio-vaccinations-who-says/"Health workers were set to launch a vaccination drive to ward off a feared outbreak of polio in Gaza after Israel and the Hamas terror group both agreed to partially pause fighting for days at a time in parts of the Strip, the World Health Organization said Thursday.
The WHO and UN children’s fund UNICEF are hoping to provide oral vaccines against type 2 poliovirus (cVDPV2) to more than 640,000 children in the Strip after a baby contracted the first confirmed case in 25 years in the Palestinian territory.
Experts say without a vaccination drive, and pauses in the fighting to facilitate the campaign, an outbreak could erupt, sinking the enclave’s civilian population into further misery after months of war.
Described as “humanitarian pauses” that will last three days in different areas of the war-ravaged territory, the vaccination campaign will start Sunday in central Gaza, said Rik Peeperkorn, World Health Organization representative in the Palestinian territories."
