US Infant Mortality Rate Drops to All-Time Low, And This Could Be Why

The U.S. infant mortality rate reached an all-time low in 2025, with fewer than 5.4 deaths per 1,000 live births, reflecting a statistically significant decline from previous years. This improvement is attributed to factors such as increased education on safe sleeping practices and the introduction of new medical interventions, including an RSV vaccine for pregnant women and an antibody shot for infants. The overall number of infant deaths also decreased, continuing a long-term trend of gradual improvement in the U.S. rate, though disparities by race remain.
