Measles outbreaks as signals of governance failure: Lessons from Bangladesh's 2026 immunisation collapse

Bangladesh's 2026 measles outbreak followed an abrupt decline in measles-rubella vaccination coverage-from above 95% to approximately 57% within a single programme cycle-after more than a decade of stable high performance. This commentary argues that the collapse reflects institutional disruption linked to health sector restructuring in 2025, rather than demand side failure or vaccine hesitancy. Administrative reorganisation weakened accountability, disrupted logistics, and led to the cancellation of planned catch up activities, removing key compensatory mechanisms at a critical moment. Routine monitoring failed to prevent collapse because coverage data were not linked to predefined thresholds or enforceable response protocols. The Bangladesh case highlights a broader policy lesson: immunisation programmes are institutional functions whose continuity depends on governance arrangements. Where demand side failure is unsupported, measles resurgences should prompt systematic review of governance and accountability.
