Gaza’s Health Ministry has confirmed that a second round of polio vaccination will start from Monday, Al Jazeera reports.

The vaccines will be administered to children under 10 for a period of three days, with the possibility of extending for an additional day.

According to AJ, only vaccinations in central Gaza have been confirmed for now, with uncertainty looming over northern Gaza, where the Israeli military is laying a deadly siege as hundreds of thousands are trapped and unable to leave.
