Is malnutrition the true driver of child mortality or does lack of vaccination pose a greater threat to children's health?

The Facts

  • An estimated 4.9 million children died before their fifth birthday in 2024, according to a report by UNICEF, the World Health Organization (WHO), the World Bank and the U.N. population division released Wednesday. Most of these deaths were preventable with low-cost interventions and access to quality health care.
  • Newborns accounted for nearly half of all under-five deaths in 2024, with complications from preterm birth making up 36% of newborn deaths and complications during labor and delivery accounting for 21%. Beyond the first month, malaria, pneumonia and diarrhea remained major killers.
  • For the first time, the report provided estimates for deaths directly caused by severe acute malnutrition, finding more than 100,000 children aged 1-59 months died from it in 2024. Pakistan, Somalia and Sudan recorded some of the highest numbers of such deaths.

The Spin


Narrative A

Vaccines are the single most powerful tool for keeping children alive, and gutting funding for them is a death sentence for millions of kids. Since 1974, immunization has saved 154 million lives — 95% of them children under five — and every dollar invested returns $54 in health and economic benefits. Letting vaccine coverage collapse means preventable diseases roar back, erasing decades of hard-won progress.

Narrative B

Malnutrition, not a lack of immunization, is the silent killer driving child mortality, and the world keeps ignoring it. A staggering 56% of under-5 deaths are attributable to malnutrition's potentiating effects on infectious disease, yet health strategies keep focusing only on severe cases. Mild-to-moderate malnutrition accounts for 83% of those deaths — fixing that gap would save the most lives.
