For the first time in 20 years, infant mortality rates are up. It’s the Supreme Court’s fault. From Igor Chudov at igor-chudov.com:
Supreme Court Magically Causes Increase in SEPSIS among newborns
The CDC just reported significant increases in infant mortality that started in 2022 and continued in 2023.
I put an annotated screenshot of the above page so you can see how increases in infant mortality match COVID vaccination of pregnant women:

Be aware that the above numbers are 12-month averages, not stats for just one quarter. Therefore, the changes are smoothed out and seem more gradual than they are.
The picture above shows that infant mortality rose following Covid vaccination of pregnant women, which CDC recommended in Aug 2021:

Several news outlets, such as ABC News, reported this:

ABC News explains how unusual these increases in infant mortality are, as this has not happened for twenty years prior:
Although rates have been declining over the last several years, this marks the first year-to-year increase in more than two decades when the rate rose from 6.8 deaths per 1,000 in 2001 to 7.0 deaths in 2002.
Both infant mortality (deaths of children less than a year old) and neonatal mortality (deaths of infants under one month old) have increased.
