A Sudan polio vaccination campaign reported on 28 October 2026 aimed to reach about 11 million children in October and November 2026, according to the source. The Federal Ministry of Health, supported by WHO, UNICEF and partners, was implementing the campaign with novel oral polio vaccine type 2 (nOPV2) to interrupt transmission of a variant poliovirus that began circulating in December 2024. The source said Sudan had confirmed poliovirus in six children and three wastewater samples in 2026.

The first round was scheduled in two phases. From 26 to 29 October, the plan targeted 6 million children aged 0–59 months in 107 localities across 12 states. In the first week of November, a further 5 million children aged 0 months to under 10 years were to be targeted in 79 localities across the five Darfur states and West Kordofan, with the age group extended there. A second nationwide round was planned about a month later.

In localities bordering South Sudan, vaccinators were to provide nOPV2 and bivalent oral polio vaccine, the source said. It added that Chad, Ethiopia and South Sudan were also running campaigns in October and November, with transit-point vaccinators along Sudan's borders.
