From Kabul to Kandahar: Inside Afghanistan’s first polio campaigns of 2025
Afghanistan carried out its first nationwide polio vaccination campaign of the year from 21 to 23 April, targeting more than 11 million children under age five. The effort was synchronized with a similar campaign in neighboring Pakistan. This is a vital strategy in the race to stop poliovirus transmission in the last two countries where the disease is endemic.
Just four weeks later, Afghanistan had a second nationwide campaign, and it was again synchronized with Pakistan’s. This back-to-back coordination is helping to close immunity gaps and intensify the fight against the virus before the season of high risk of transmission begins. Despite operating in a difficult environment, Afghanistan’s polio eradication program continues to adapt and innovate to protect every child.

The last mile: Reaching every child in Pakistan
If you visited the House of Friendship at the 2025 Rotary International Convention in Calgary, Canada, you may have seen the new video from UNICEF that follows polio vaccination teams in two parts of Pakistan: Murree and Mithi. Murree is in a mountainous region, while Mithi is in a vast desert. This short film was made in February, during the first polio vaccination campaign in Pakistan this year, when over 400,000 frontline health workers visited homes across the country to vaccinate 45 million children ages 5 and under. The film shows the time and effort it takes to be able to reach children through tough terrain, especially in remote areas.
What the latest immunization estimates mean for polio eradication
The newly released estimates of national immunization coverage from the World Health Organization and UNICEF indicate that global coverage for the third dose of polio vaccine in routine immunization systems was 84% in 2024. That’s the same as in 2022 and 2023 but still below pre-pandemic coverage of 86% from 2017 through 2019.
While immunization rates show signs of recovery in many countries, gaps persist, particularly in fragile and conflict-affected settings. There, the number of children who have not received any vaccine remains high. Ensuring comprehensive coverage and strengthening health care systems remain crucial for achieving a polio-free world.
