18.5 million tiny arms down, 3.4 million to go: Bangladesh hunts down the last measles gaps

Since April, Bangladesh's vaccinators have reached 18.5 million children in a three-phase measles campaign — and now they're going after the 3.4 million who slipped through. The special drive covers every child aged 6 to 59 months through October 31, with 1 million doses held in reserve for emergencies. It is the country's largest child-health mobilisation this year, built on cold chains, community clinics and health workers who go door to door.
