WHO describes an ongoing national vaccination effort amid two poliovirus outbreaks, with another round planned for November.
What the record says
WHO’s Africa office reports that South Sudan is conducting a nationwide polio vaccination campaign targeting about 3.9 million children under five. The Ministry of Health leads the effort with WHO, UNICEF and other partners amid circulating vaccine-derived poliovirus types 1 and 2.
The October 30 update says 73 counties had completed the first round by October 19, six were still implementing it and one had not started because of access challenges. A second round is planned for November 2026. These reported activities do not establish that transmission has ended or that nationwide coverage is complete.
