This article is for all those who lost an infant — and never got an answer.
Sudden Infant Death Syndrome (SIDS) is the most common cause of death in infants between one month and one year. The cause is by definition unknown — “sudden” and “unexpected” is the medical diagnosis.
At the same time, the first weeks and months of life coincide with the start of the vaccination schedule. In Germany, infants are vaccinated from the 6th week of life — against diphtheria, tetanus, pertussis, Hib, hepatitis B, polio, pneumococci, meningococci C, and rotaviruses.
The temporal overlap is unavoidable. The question is: is it only temporal, or is it causal?
What the VAERS Data Shows #
An analysis of the US VAERS database (Vaccine Adverse Event Reporting System) over a period of 30 years (1990–2019), published in a peer-reviewed journal in 2021:
Of 2,605 reported infant deaths following vaccination:
- 58% clustered within 3 days after vaccination
- 78.3% occurred within 7 days after vaccination
This is not speculation. This is a statistical finding from a published study. The clusters are real.
The standard response is: SIDS occurs frequently in this age range anyway — so the temporal proximity to vaccination is coincidence. That’s possible. It’s also possible that it’s not coincidence.
What’s missing: A study that tests these clusters methodologically against a genuine control group — infants who were not vaccinated during this period.
The Methodological Problem #
The officially cited studies “demonstrating no connection” have a systematic flaw: they compare vaccinated infants with other vaccinated infants.
That’s the same problem as in Part 2 of this series: the control group is contaminated.
A fully unvaccinated control group doesn’t exist — either for ethical reasons (according to official justification) or because social pressure to vaccinate was too high during the decades studied.
Without a real control group, the statement “no elevated risk” cannot be methodologically demonstrated. It may be true — but it cannot be proven with the available data.
What the Charité Says — and Doesn’t Say #
The Charité published a study showing: higher vaccination rates = less frequent SIDS. That sounds like a clear finding against a connection.
But: this study is a population-level correlation study. It cannot distinguish between “vaccination protects against SIDS” and “other factors simultaneously influencing vaccination rates and SIDS rates.”
During the same period as rising vaccination rates there were also: better education about safe sleeping positions, decline in smoking in households with infants, better monitoring devices, changed breastfeeding behavior.
The correlation proves no causation — in either direction.
What This Article Does Not Say #
This article does not say: vaccinations cause SIDS.
It says: the question was never methodologically properly examined. The existing studies have systematic flaws. The 58% clustering in VAERS is a statistical finding that deserves an explanation — not a media fact-check with the label “❌ False.”
What Families Deserve #
Families who have lost a child deserve:
- A complete investigation — including temporal proximity to vaccinations
- No premature exonerations
- Real research with real control groups
- The ability to ask the question — without being labeled “anti-vaxxers”
This is not a radical demand. It is the minimum that science should deliver.
If you lost a child to sudden infant death and believe there may be a connection to a vaccination: in Germany, you can file reports with the Paul-Ehrlich-Institut (pei.de). In the US, with VAERS (vaers.hhs.gov). Every report counts for the data situation.
