evidence: A recent federal report shows a 3% increase in the U.S. infant mortality rate between 2021 and 2022, which is the first statistically significant rise in 20 years. The cause of the uptick is unknown, but there’s no evidence that it’s due to COVID-19 vaccination, as some social media posts baselessly suggest. A recent report from the Centers for Disease Control and Prevention showed that in 2022, 5.6 infants out of every 1,000 live births died before they turned 1 in the U.S., a 3% increase over 2021. This returns the infant mortality rate, which has steadily fallen over the decades, to the 2019 level. [...] The rise in 2022 was driven by significant increases in mortality for several categories measured in the report — in infants born to women ages 25 to 29; in infants born in four states (Georgia, Iowa, Missouri and Texas); in infants of American Indian and Alaska Native and white women; in infants born preterm; and in male babies. Mortality rates also increased in cases of maternal complications and bacterial sepsis, two of the 10 leading causes of infant death.
