Over 2.9 million children immunised against polio in Katsina

Katsina State is celebrating a significant public health achievement: 11 months without a single new polio case. This remarkable feat, announced by Heartland Alliance LTD/GTE to mark World Immunisation Week, is the result of a massive immunization campaign that successfully vaccinated over 2.9 million children. This progress is particularly noteworthy given Katsina's past status as one of Nigeria's highest-risk areas for polio.

Eleven months without a new polio case in a state that was once among Nigeria’s highest-risk geographies is real progress.

However, the celebration is tempered with a stark warning from Dr. Bartholomew Ochonye, CEO of HALG. He emphasizes that the poliovirus requires only one missed child to persist, underscoring the fragility of the current gains. The campaign, while successful, also exposed critical weaknesses in Nigeria's immunization infrastructure. A concerning discovery was that over 50,000 children, many in hard-to-reach areas and absent from official records, had never received any vaccine prior to this intervention. This highlights the ongoing challenge of ensuring equitable access to essential healthcare services across the nation.

But the poliovirus needs only one missed child to persist. Finding, counting, and planning for every child is not preparation for the real work; it is the real work.

The intervention, which involved extensive house-to-house enumeration and mapping of settlements, exceeded initial targets. Yet, public health experts point out that such granular planning is crucial in northern Nigeria, where historical challenges of weak data systems, insecurity, and vaccine hesitancy have hampered immunization efforts. While community engagement has reduced vaccine hesitancy by 40 percent, it remains a concern, as does insecurity, which impeded access to some areas. The success in Katsina is a testament to dedicated efforts, but it also serves as a critical reminder of the persistent work needed to achieve comprehensive immunization coverage for every child in Nigeria.

over 2.9 million children were vaccinated across Katsina, contributing to the state’s current streak without a circulating vaccine-derived poliovirus type 2 (cVDPV2) case.
