Are vaccines at two months tied to death?

Peter McCullough’s group claims that Louisiana records show vaccinated two-month-old babies are 112% more likely to die.

The claim seems to come from a paper by Karl Jablonowski and Brian Hooker of Children’s Health Defense, titled Increased Mortality Associated with 2-Month Old Infant Vaccinations.

The paper was a preprint, which means it was shared online before other scientists carefully checked it for mistakes. In peer review, experts look at a study’s methods, data, and conclusions to see if they are strong and fair.

This paper was not peer reviewed. Instead, the paper was posted on Preprints.org in December 2025, but it was removed from the website in January 2026. After it was removed, the authors uploaded it somewhere else. When you look closely at how the authors studied the numbers, there are some big problems.

First, they do not explain the medical reasons that the children died. Without knowing what caused the children’s deaths, there is no way to know whether vaccines had anything to do with them.

Second, they used a very narrow definition of “vaccinated.” This means they counted children as vaccinated only during a short period. They ignored children who got vaccines before or after that time period. That can make the results misleading because it leaves out a lot of information.

Third, there are problems with their confidence intervals, which are ranges of numbers scientists use to show how sure or unsure they are about a result. Their confidence intervals cross over 0. When a confidence interval crosses 0, it usually means the result could have happened by random chance. In science, this is called not statistically significant. Their results are not strong enough to say that it probably did not happen by chance. In other words, it could be a coincidence.

The authors do not clearly explain this problem, even though it undermines everything they say in the paper.
