Even small disruptions can allow immunity gaps to widen over time
Bangladesh, once celebrated for its vaccination achievements, is now confronting a measles outbreak that has claimed more than 250 lives — most of them young children — in what stands as the country's deadliest such crisis in two decades. The tragedy unfolded against a backdrop of rapid political succession, with three governments cycling through power in under two years, each transition leaving public health systems more fractured than before. Vaccination coverage, which had held above 86 percent for years, fell to barely 59 percent in 2025, opening silent gaps in the immunity of an entire generation of children. The courts are now being asked to answer what politics could not: who is responsible when a preventable disease is allowed to become a catastrophe.
- More than 250 people — overwhelmingly children between one and fourteen — have died from measles since mid-March, with 7,500 suspected cases spreading across nearly all of Bangladesh's districts.
- Vaccination coverage collapsed from a reliable 86–103% range to just 59.6% in 2025, a freefall that left hundreds of thousands of young children exposed to a disease that had been largely held at bay for years.
- Three governments in less than two years shattered the routine immunization infrastructure, and a scheduled 2024 nationwide measles drive never happened — the immunity debt accumulated quietly until it became visible in death tolls.
- A Supreme Court petition now seeks travel bans on former interim chief Muhammad Yunus and his advisers, alleging a deliberate and unlawful push to privatize measles vaccination that directly contributed to the crisis.
- The High Court has given the current government four weeks to justify its failure to prevent the outbreak, while an emergency vaccination drive races to reach children across a nation already deep in grief.
Bangladesh, a country that had built its global reputation on vaccination success, is now burying its children. Since mid-March 2026, more than 250 people have died from measles — the deadliest outbreak in twenty years — with the vast majority being children under fourteen. By late April, nearly 7,500 suspected cases had been recorded across 58 of the country's 64 districts.
The outbreak did not arrive without warning. It arrived amid political chaos. Three governments cycled through power in under two years: Sheikh Hasina's fall in August 2024, Muhammad Yunus's fifteen-month interim administration, and the Bangladesh Nationalist Party's assumption of control in February 2026. Each transition fractured the machinery of public health a little further. Vaccination rates that had held between 86 and 103 percent for years collapsed to 59.6 percent in 2025. A nationwide measles drive planned for 2024 never happened. Immunity gaps accumulated silently across the child population.
The legal reckoning has been swift. A Supreme Court lawyer filed notice seeking a travel ban on Yunus and key members of his interim cabinet, alleging they had pursued an unlawful scheme to shift measles vaccination from government hands to private providers. The High Court, hearing a separate public interest case, gave the current government four weeks to explain why its failure to prevent the outbreak should not be declared illegal, and ordered uninterrupted vaccine supplies with a progress report due in two weeks.
The new Health Minister's public statement — claiming measles vaccines had not been administered in eight years, a claim contradicted by documented campaigns — only deepened public confusion and distrust. An emergency vaccination drive launched in late April, but for more than 250 families, it came too late. The question Bangladesh now faces is whether its courts can establish accountability, and whether a nation that once showed the world how to protect its children can find its way back to that promise.
Bangladesh, a nation that had built its international reputation on vaccination success, is now burying its children. Since mid-March, more than 250 people have died from measles—the deadliest outbreak the country has seen in twenty years. The vast majority were children between one and fourteen years old. By late April, health authorities had documented 7,500 suspected cases across 58 of the country's 64 districts, with nearly four out of five cases occurring in children under five.
The outbreak arrived at a moment of political turbulence. Bangladesh had cycled through three governments in less than two years: Sheikh Hasina's Awami League ruled until August 2024, when violent protests forced her from power. Muhammad Yunus then led an interim government for fifteen months before the Bangladesh Nationalist Party, under Tarique Rahman, took control in February 2026. Each transition left the machinery of public health fractured. The most recent shift has become the focus of legal blame. On April 6, a Supreme Court lawyer filed notice seeking a travel ban on Yunus and members of his interim cabinet, alleging they had pursued what the legal filing called an "unlawful and malicious" effort to shift measles vaccination from government control to private providers.
The numbers tell the story of a system in collapse. Vaccination rates for children at twelve months old had held steady between 86 and 103 percent from 2017 through 2023. In 2025, under Yunus's interim government, that rate plummeted to 59.6 percent. Bangladesh's routine immunization schedule, managed through its Expanded Programme on Immunisation, had been the backbone of public health for decades. The last special nationwide measles vaccination drive had occurred in 2020. The next one was supposed to happen in 2024, but the political upheaval and the lingering effects of the Covid pandemic disrupted the schedule. By the time the current government took office, immunity gaps had accumulated silently across the child population.
Health Minister Sardar Sakhawat Hossain, part of the new BNP administration, offered a statement that only deepened public confusion. He announced that the last measles vaccines had been administered eight years prior—a claim that contradicted the documented vaccination campaigns of more recent years. Hossain blamed both the Hasina and Yunus governments for mismanagement and poor decisions that had created shortages in vaccine stockpiles not just for measles but for six other diseases as well. A deputy director of the Health Department attributed the disruption in the special vaccination drive to the pandemic and to what he called "the political situation." The World Health Organisation, in a careful statement, noted that Bangladesh had maintained strong immunization coverage historically, but that even modest interruptions could allow immunity gaps to widen over time.
The legal response has been swift. The Supreme Court lawyer M Ashraful Islam named not only Yunus but also his key advisers—Asif Nazrul, Syeda Rizwana Hasan, and Nurjahan Begum—as well as the former press secretary Shafiqul Alam and relevant personal staff. The petition demanded investigation into the alleged scheme to privatize vaccination for a disease as serious as measles. Meanwhile, the High Court, hearing a public interest case, issued its own orders: the government was given four weeks to explain why its failure to prevent the outbreak should not be declared illegal. Authorities were instructed to ensure adequate and uninterrupted supplies of vaccines, syringes, and other materials, with a progress report due in two weeks.
The emergency vaccination drive began on a Sunday in late April, a scramble to reach children across a nation reeling from loss. But the damage had already been done. Over 250 families had already experienced the worst outcome. The question now is whether the courts can establish accountability, whether the new government can rebuild the vaccination infrastructure, and whether Bangladesh can recover the public health standing it had spent decades constructing.

The Hearth Conversation Another angle on the story
How does a country known for vaccination success end up with its worst measles outbreak in twenty years?
It's a combination of political disruption and a system that depends on continuity. When governments change rapidly, vaccination schedules break. The special measles drive that should have happened in 2024 didn't. By 2025, routine vaccination rates had dropped from over 80 percent to under 60 percent. That's not a small slip—that's a generation of children losing protection.
Was the Yunus government deliberately trying to privatize vaccination, or is that just political blame-shifting?
The legal filing alleges an "unlawful and malicious" effort to shift measles vaccination to the private sector. Whether that was deliberate policy or a consequence of broader mismanagement isn't yet established. But the effect is the same: children didn't get vaccinated, immunity gaps opened up, and measles found room to spread.
Why does it matter that 91 percent of cases are children between one and fourteen?
That's the age group that should have been protected by routine vaccination. If the immunization program had been working, most of those children wouldn't have gotten sick. The fact that they did means the system failed at its most basic function.
What happens now with the court cases?
The High Court has given the government four weeks to explain itself and two weeks to show progress on vaccine supply. The Supreme Court is considering a travel ban on Yunus and his advisers. But courts can't vaccinate children. The real question is whether the current government can rebuild what was broken before more people die.
Is this a uniquely Bangladesh problem, or could it happen anywhere?
It could happen anywhere. The WHO made that point: even small disruptions in vaccination programs can create immunity gaps that accumulate over time. Bangladesh just happened to experience multiple disruptions at once—a pandemic, political upheaval, and a change in government priorities. The system was fragile.
