The World Health Organization (WHO) and the UN Children’s fund (UNICEF) launch this week a new round of polio vaccination for children in Government of Yemen-controlled areas.
The 3-day campaign, running from 12 to 14 July 2025, aims to boost population immunity in high-risk areas and prevent further spread of the virus by administering novel oral polio vaccine type 2 (nOPV2) to more than 1.3 million children in 120 districts across 12 governorates. The intervention comes in response to cases in the community and the continued confirmed circulation of variant type 2 poliovirus (cVDPV2) in environmental samples.
“Yemen remains at high risk for poliovirus outbreaks due to protracted conflict, weakened health systems and low routine immunization coverage,” said Acting WHO Representative in Yemen Dr Ferima Coulbibaly-Zerbo. “With polio virus continuing to circulate and cases confirmed in 2025, these campaigns are essential to interrupt transmission and protect every child from the debilitating effects of polio.”
Since 2021, Yemen has reported a total of 282 cVDPV2 cases across 122 districts in 19 of the country’s 22 governorates, with 98% of cases occurring in children under the age of 5. The overall epidemiological trend highlights the urgent need for nOPV-2 vaccine to halt cVDPV circulation in southern governorates and protect children from the disease.
The campaign is led by the Ministry of Public Health and Population (MoPHP) with support from the World Health Organization (WHO), UNICEF and the Global Polio Eradication Initiative (GPEI).
It will be carried out by almost 7,000 vaccination teams, including over 6,000 mobile door-to-door teams and 800 teams at health facilities. Nearly 2,000 team supervisors and 240 district-level supervisors will oversee the campaign, with technical support from national and partner agencies.
“The campaign is an important and urgent step to protect children from being paralysed by the polio virus. With confirmed cases of polio among Yemeni children, an imminent threat persists, especially for every unvaccinated child. But, through vaccination, we can keep our children safe,” said Peter Hawkins, UNICEF Representative to Yemen.
WHO and UNICEF, as core partners of GPEI, are fully committed to supporting the Government of Yemen in its efforts to eradicate polio and strengthen routine immunization services. Continued investment and coordinated action are essential to ensure no child is left behind.
