The biggest issue is that it only looked at children who had already died and then compared groups inside that \u201conly deaths\u201d set, so it cannot tell whether vaccines raise the chance of death in the real world, where most babies live; this kind of picking your study group based on the outcome\u00a0can create a false link. This is called\u00a0selection bias<\/a>.<\/p>\n

Another major problem is that their \u201cunvaccinated\u201d group is not truly unvaccinated: the paper says a child had to have an immunization record match and \u201cminimally have been immunized at least once,\u201d and \u201cunvaccinated\u201d just means \u201cnot vaccinated in days 60\u201390,\u201d so the comparison is not \u201cvaccinated vs. unvaccinated,\u201d but \u201cvaccinated in this window vs. vaccinated at some other time or not recorded in this window.\u201d<\/p>\n

Timing also matters a lot: babies who are sick, premature, or have health problems may get vaccines later, may miss visits, or may have different care, and those same health problems also change the risk of death, so the groups can be different from the start. This is called a\u00a0confounding variable<\/a>.<\/p>\n

The study also does not clearly fix these differences with strong, detailed adjustments (like prematurity, birth weight, NICU stay, major diagnoses, and access to care), so it can mix up \u201cwho got vaccinated on time\u201d with \u201cwho was healthy enough to come in on time.\u201d<\/p>\n

On top of that,\u00a0vaccine safety\u00a0<\/a>is normally judged with much stronger methods: careful trials before approval and large safety monitoring systems after approval that follow vaccinated and unvaccinated people over time using proper denominators, instead of studying only people who died.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]\n<\/div>","protected":false},"excerpt":{"rendered":"
