The second round of an emergency polio vaccination campaign is scheduled to start on 14 October 2024 in Gaza, to vaccinate an estimated 591 700 children under ten years of age with a second dose of the novel oral polio vaccine type 2 (nOPV2) vaccine.

This follows a first round, which was successfully implemented from 1-12 September 2024 and vaccinated 559 161 children, or an estimated 95% of eligible children at governorate level, according to independently conducted post-campaign monitoring. As with the first round, the second round will have three phases, each involving three campaign days and one catch-up day.

A minimum of two doses of nOPV2 are needed to interrupt poliovirus transmission. However, this will only be achieved if at least 90% of all children are vaccinated in all communities and neighbourhoods. In this round, vitamin A will be co-administered alongside polio vaccine, to help boost overall immunity among children between the ages of two and nine years.
