Infants vaccinated in their second month of life were more likely to die in their third month than unvaccinated infants, according to an analysis of data obtained from the Louisiana Department of Health. Female and Black infants died at higher rates than male or white babies.

Children’s Health Defense scientists Brian Hooker, Ph.D., and Karl Jablonowski, Ph.D., conducted the analysis, which was published Monday on Preprints.org.

Depending on which vaccines they received, vaccinated children were between 29%-74% more likely to die than unvaccinated children. Vaccinated Black infants were 28%-74% more likely to die, and vaccinated female infants had a 52%-98% greater risk of death.

Overall, children who received all six vaccines recommended for 2-month-olds were 68% more likely to die in their third month of life, the data showed.

Hooker and Jablonowski determined the death rates by analyzing immunization and mortality records from the Louisiana Department of Health for children who died before age 3 months between 2013 and 2024.

“This very important paper represents one of the first studies on the cumulative effect of vaccines given at 2 months of age following the Centers for Disease Control and Prevention’s (CDC) recommended schedule,” Hooker told The Defender.

He added:

“The highest infant mortality rates were seen when children received all six of the recommended vaccines in one visit. In addition to elevated mortality, the vaccination schedule also increased the likelihood that children were more likely to die of non-leading causes of death.
