How do vaccinated children compare to unvaccinated children on all-cause mortality, serious adverse events, or long-term health.
The short version: the evidence you were given answers a different question.
None of the studies in this retrieval compares vaccinated children to unvaccinated children on all-cause mortality, serious adverse events, or long-term health. The closest one is a 2000 study from Guinea-Bissau [4] that found children who received diphtheria-tetanus-pertussis (DTP) vaccine had nearly double the mortality (mortality ratio 1.84, confidence interval 1.10 to 3.10) compared to unvaccinated children, while BCG and measles vaccines were associated with lower mortality. That study was observational and from a low-income country with high background disease rates. The remainder of the evidence covers vaccine coverage rates in El Salvador [1], cost savings in the US [3], the COVID-19 pandemic's effect on Swiss vaccination timeliness [5], and a review of COVID-19 vaccine myocarditis [9]. Not one study tracks a US or European cohort of vaccinated versus unvaccinated children from infancy through childhood counting all-cause death or serious harm. The most informative study design was never run. The burden of proof has not been met.
My call: the evidence provided does not show whether vaccinated children do better or worse than unvaccinated children on the outcomes that matter most. The data to answer this question does not exist in this retrieval. Confidence: high that the retrieval lacks it, not clear what the answer is.
