Africa Makes Progress in Polio Eradication Efforts Amid Ongoing Challenges

Health leaders from across Africa gathered in Nairobi to review progress and chart a path forward for ending all remaining poliovirus transmission on the continent. The meeting, convened by the Global Polio Eradication Initiative, focused on intensifying operations in areas where variant polioviruses continue to circulate. Participants reviewed the situation in the Lake Chad Basin and the Horn of Africa, agreeing on concrete actions to strengthen coordination and accelerate vaccination campaigns.

Key Takeaways:

• The Global Polio Eradication Initiative (GPEI) Action Plan provides a framework for intensified efforts to eradicate polio in Africa, emphasizing a smarter, leaner, and more integrated approach.
• The hexavalent vaccine, introduced in Senegal and Mauritania, combines protection against six diseases, including polio, in a single shot, and is named by Time Magazine as one of 2025's 100 most important innovations.
• Countries are scaling up use of the novel oral polio vaccine type 2 (nOPV2) to stop variant outbreaks safely and quickly, and exploring new tools such as microneedle patches and needle-free injectors to simplify delivery.
• In Nigeria, over 100 million children are being vaccinated against measles, rubella, and polio as part of one of the largest integrated immunization campaigns in history.
• Joint surveillance and cross-border vaccination activities in the Lake Chad region continue to form a protective "dam" against the virus.
• Partnership and community are at the core of the polio eradication effort, with contributions from governments, WHO regional offices, Rotary International, and civil-society volunteers.
