350,000 Kids Vaccinated in Nigeria's Diphtheria Fight

Nearly half a million children in northeastern Nigeria now have protection against a disease that has killed more than 2,000 people across the country since 2022.

Doctors Without Borders teamed up with the Borno State Ministry of Health to run a two-round vaccination campaign in Maiduguri, reaching far beyond their initial goals. The first round in February 2026 vaccinated 490,000 children under 14, exceeding the target by over 100,000 kids. A second round in April strengthened immunity for 360,000 of those children.

The timing couldn't be more critical. Nigeria is facing one of its worst diphtheria epidemics ever, with nearly 66,000 suspected cases and 2,229 deaths reported since the outbreak began. Borno state has been hit especially hard, with Doctors Without Borders treating more than 7,400 suspected cases since 2023.

Diphtheria spreads through coughs and sneezes, causing a thick membrane to form in the throat that can block breathing. The infection can damage the heart, nerves, and kidneys. Without treatment, about 30% of unvaccinated people die from the disease, with young children facing the highest risk.

Communities responded enthusiastically to the vaccination efforts. Health workers fanned out across Maiduguri, spreading awareness and bringing vaccines directly to families. The campaign even led to more people seeking treatment, as heightened awareness helped parents recognize symptoms earlier.

The Ripple Effect

The success in Maiduguri shows what's possible when international organizations and local governments work together. Doctors Without Borders provided storage, transportation, and health promotion while the Ministry of Health supplied the vaccines. This partnership model is now supporting diphtheria efforts across four Nigerian states.

"This vaccination will help to significantly boost immunity levels of children below 14 years old in Maiduguri," said Nao Muramoto, MSF emergency coordinator for the project. The proactive approach is essential for controlling and preventing the disease's spread.

The campaign faced real constraints, though. Limited vaccine supplies meant not every child in Borno state could be reached. Health officials stress that sustained routine immunization and better access to volatile areas remain crucial for preventing future outbreaks.

Beyond fighting diphtheria, Doctors Without Borders also runs a 60-bed maternity hospital and nutrition centers in the region, treating severely malnourished children. It's a comprehensive approach to health care in an area that desperately needs it.

These 350,000 newly protected children represent more than statistics; they're families who can sleep easier knowing their kids have a shield against a dangerous disease.
