Infant mortality in the U.S. fell to an all-time low in 2025 thanks to antibody shots and RSV vaccines
Infant mortality in the U.S. reached an all-time low in 2025, with fewer than 5.4 deaths per 1,000 live births, according to preliminary data from the Centers for Disease Control and Prevention. This decrease, though small, represents hundreds of fewer infant deaths annually. While the exact causes are still being studied, public health efforts such as antibody shots and RSV vaccines for pregnant women, along with increased education on safe infant sleeping practices, are believed to have contributed to this positive trend.
