The U.S. infant mortality rate fell to an all-time low, though it still trails other similar nations

According to CDC data, the U.S. infant mortality rate dropped to an all-time low in 2025. This decline is attributed to the use of antibody shots and RSV vaccines. While the rate is significantly lower than it was three decades ago, the U.S. still trails other similar high-income nations in this metric. The data confirms a record low for the country despite the persisting gap compared to other developed nations.
