The experts raised the concern during a multi-stakeholder engagement on immunisation financing meeting convened by the Vaccine Network for Disease Control (VNDC) under the PREACH Project, funded by Gavi, the Vaccine Alliance through GHAI.
They said that the repeated partial disbursements, ranging between 10 per cent and 30 per cent from 2023 to 2026, were weakening immunisation systems and disrupting vaccine procurement and distribution across the country.
Mrs Chika Nwankwo, Head of Programmes, VNDC, said the pattern of delayed and incomplete releases had made planning difficult and unsustainable for immunisation managers.
“This fire brigade approach is not sustainable,” Nwankwo said.
She said that while budgetary allocations for vaccines were often approved, the timely release of funds remained the major challenge affecting service delivery.
“Appropriation is not the problem; the problem is timely release. If funds are not released on time, vaccines can not be purchased, and when vaccines are not purchased, there will be a stock-out,” she said.
She said that Nigeria had previously experienced vaccine stock-outs, adding that emergency interventions are required to stabilise supply in some instances.
“We were already having a stock-out. It was after our intervention that about 30 per cent of the 2025 immunisation fund was released, but that is not sustainable,” she said.
She stressed the need for a more predictable and structured financing system involving all tiers of government to ensure uninterrupted vaccine availability.
Also speaking, Chief Executive Officer of VNDC, Dr Chika Offor, called on the government to urgently release outstanding immunisation funds, warning that delays are worsening the country’s zero-dose burden.
“What we need in Nigeria right now is for the government to release vaccine funds so that we can buy vaccines that are very important to save the lives of our children and reduce zero dose,” Offor said.
She said that while about N231 billion was appropriated for immunisation, only N68 billion had been released so far, creating a significant funding gap.
She said more than eight million children were born annually in Nigeria and require routine immunisation, alongside other vulnerable groups.
Also, Dr Sheikh Kabir, UNICEF Health Manager for Immunisation in Nigeria, said both funding and accountability challenges persisted, but noted that delays in fund disbursement remained a critical barrier.
“The issue is not always appropriation; it is the disbursement. Funds are sometimes delayed or inadequate, and that affects procurement,” Kabir said.
He said that Nigeria required over 150 million dollars annually for vaccine procurement to sustain immunisation programmes nationwide.
He called for improved efficiency in fund release processes to avoid disruptions in vaccine supply chains and strengthen routine immunisation coverage across the country.(NAN)
