A Predictable Tragedy: How Administrative Negligence Revived Measles in Bangladesh

A vaccine system dismantled mid-flight — and the children who paid the price

The first child died quietly. Then another, and then dozens more. By the time the media began to report on the situation, more than 150 children had died, not from a novel pathogen, but from measles. A disease Bangladesh had controlled for nearly three decades. A disease with a low-cost, effective vaccine. A disease that should never have returned this way.
This outbreak was not a failure of medical science. The vaccines exist, the protocols are well established, and the epidemiology is well understood. The failure was administrative: a gradual dismantling of a system that had protected children reliably for 27 years. Unless the origins of this breakdown are understood and addressed, there is little to prevent it from happening again.
Key coverage indicators illustrate the scale of the collapse: MR1 coverage peaked at around 102 percent in 2017–2018, remained 93.6 percent in 2022 despite the COVID-19 pandemic, and then declined to 86.6 percent in 2024, reaching a warning threshold. In 2025, coverage plunged to approximately 59–60 percent, the lowest level since 1989 and far below the 95 percent threshold required to maintain herd immunity. Even before this collapse, more than 70,000 children were estimated to be "zero-dose" for routine immunization.

A SYSTEM BUILT OVER 27 YEARS — DISMANTLED

Bangladesh was once a high-burden setting for measles. That trajectory began to change with the launch of the Expanded Programme on Immunization (EPI) in 1979, and more decisively with the introduction of the Sector-Wide Approach (SWAp) in 1998. SWAp replaced fragmented, donor-led projects with a unified, government-led sector program, improving coherence, predictability, and accountability in health financing and service delivery.
Within this framework, Operational Plans (OPs) were developed as the backbone of the Health, Population and Nutrition Sector Program (HPNSP). Each OP was headed by a Line Director — a technical leader with explicit authority to manage planning, budgeting, and, crucially, vaccine procurement. Line Directors could order vaccines directly from UNICEF and Gavi, bypassing lengthy political approval processes and ensuring continuity of supply.
For nearly three decades, this architecture held. Routine coverage levels remained above 90 percent, and major measles outbreaks were prevented. This success, however, created an illusion of permanence.
In 2025, the interim government abolished the OP system and replaced it with the so-called "Umbrella Approach," a centralized, project-based model intended to reduce duplication and increase control over public spending. The transition was poorly sequenced. The OPs were shut down before the new system's roles, authorities, and legal instruments were fully defined. Without an approved procurement framework and designated signatories, the authority to buy vaccines effectively disappeared.

WHEN TECHNICAL AUTHORITY DISAPPEARED

The impact on measles immunization was swift and severe. MR1 coverage fell from 86.6 percent in 2024 to about 59.6 percent in 2025, erasing nearly one-third of the country's measles protection in a single year. Bangladesh was pushed back to coverage levels last seen in the late 1980s, with predictable epidemiological consequences.
The decision to abolish OPs did not merely change organizational charts; it removed the technical authority that had kept vaccine supply chains functioning. With the OP system went the Line Director positions, and it remains unclear whether equivalently empowered roles were ever created under the Umbrella Approach.
As governance structures shifted, vaccine stockpiles steadily dwindled. No new orders were placed because no one held undisputed legal authority to sign procurement contracts. By the time the measles outbreak began, central stores had effectively run out of several essential antigens, and procurement files remained stalled in bureaucratic limbo.

FUNDING COLLAPSE, WORKER STRIKES, AND MOUNTING VULNERABILITY

The governance changes unfolded against a backdrop of fiscal uncertainty. The fourth HPNSP formally ended in June 2024. In March 2025, the government scrapped the proposed fifth HPNSP, citing financial concerns and opting instead for a project-based approach without a clear, medium-term funding envelope for essential services. This decision effectively abandoned a 27-year sector-wide model that had underpinned routine immunization and other core public health functions.
At the same time, the workforce responsible for delivering vaccines came under acute strain. Health assistants — the front-line workers tasked with serving approximately 120,000 EPI outreach centers across the country — launched a sit-in at DGHS headquarters. They demanded resolution of long-standing grievances, including pay grade upgrades and an end to salary discrimination. The work stoppage lasted for weeks and disrupted routine outreach services nationwide.
By November 2025, routine immunization was already significantly disrupted; by March 2026, when a national measles-rubella campaign was scheduled, many workers refused to participate. In parallel, global partners had already warned of growing immunity gaps. A joint communiqué from Gavi, UNICEF, and WHO in April 2025 estimated that Bangladesh had roughly 70,000 zero-dose children and 400,000 under-immunized children even before the administrative collapse. The subsequent coverage drop in 2025 added several hundred thousand more susceptible children, creating ideal conditions for a large-scale resurgence.

GLOBAL ADVOCACY, DOMESTIC FAILURE

Dr. Muhammad Yunus, the Nobel Peace Prize laureate who became chief adviser of Bangladesh's interim government in August 2024, is internationally recognized as a leading voice for vaccine equity. He has argued that vaccines should be treated as a "Global Common Good" and has criticized patent and pricing barriers that limit access for low- and middle-income countries.
Yet, there is a stark dissonance between his global advocacy and the domestic outcomes observed during his tenure. While he travelled to international summits promoting his "Three Zeros" vision, a "fourth zero" was emerging in Bangladesh's clinics: zero vaccine stock.
The failure appears less a matter of intent than of governance capacity. By dismantling the HPNSP framework and OP system without establishing a fully functional replacement, the administration effectively cut the brake lines of a moving vehicle. No nationwide measles campaign was conducted during this period; the last such campaign had been held in December 2020. The proclamation of vaccines as a global public good thus translated into a local tragedy, as administrative obstacles prevented vaccines from reaching the children who needed them most.

EMERGENCY RESPONSE — TOO LITTLE, TOO LATE

On April 6, 2026, the government launched an emergency measles-rubella vaccination campaign targeting approximately 1.3 million children in 30 upazilas across 18 high-risk districts. This campaign, supported by WHO, UNICEF, and other partners, was a critical step in containing the immediate outbreak.
However, the intervention came after substantial and avoidable loss of life. More than 150 suspected measles deaths had already been reported, the vast majority among young children. Surveillance data from 2025 had already signalled a looming crisis as coverage declined sharply and immunity gaps widened. In a robustly governed system, corrective action — including targeted campaigns, catch-up activities, and supply-chain strengthening — would have been deployed months earlier.
Emergency campaigns, by design, treat the symptoms of system failure rather than its causes. While the April 2026 campaign likely averted further deaths and helped reduce transmission, it did not resolve the underlying administrative vacuum. The Umbrella Approach remains only partially operational, and a permanent, legally grounded mechanism for vaccine procurement and delivery has yet to be fully restored. Without such structural corrections, future outbreaks are not a question of "if" but "when."

LESSONS AND STRUCTURAL RECOMMENDATIONS

The 2026 measles outbreak in Bangladesh was a predictable outcome of administrative negligence, governance gaps, and underinvestment in system resilience. A system that had safeguarded children for more than a generation was dismantled without a viable replacement. Funding was frozen or delayed, health workers were demoralized and underpaid, and technical authority was diffused to the point of paralysis.
Reversing this damage requires urgent structural action that goes beyond emergency campaigns and ad hoc fixes. Four priority areas emerge from this analysis:
