Families deserve answers, transparent safety monitoring and the freedom to ask difficult questions.
Every parent’s worst nightmare is losing a baby without knowing why. Sudden Infant Death Syndrome (SIDS) is devastating precisely because it can occur without an identified cause.
October is SIDS Awareness Month. It should be a time not only to promote safe sleep, but also to ensure that every credible safety concern involving infant deaths is investigated thoroughly, independently and transparently.
Vaccines are routinely administered during the first months of life—the same period when SIDS occurs. When an infant dies hours or days after receiving a round of shots, parents have every reason to demand answers. They know what happened to their child, and their observations deserve to be taken seriously—not brushed aside or dismissed. No family should have to fight to have its concerns heard, and no reported infant death should escape thorough investigation.
A Question Researchers Have Examined for Decades
Researchers have examined possible associations between vaccination and sudden infant death since at least the 1980s.
A 1983 study in Pediatric Infectious Disease investigated a possible temporal association between DTP vaccination and SIDS. Of the 53 infants who had received DTP, six died within 24 hours of vaccination and 17 within one week—significantly more than the researchers expected.
The historical record is not as simple as saying every possible relationship has been ruled out.
The Institute of Medicine's 2003 review found that there was not enough evidence to rule out the possibility that certain vaccines can cause sudden infant death.
And a 2011 Italian study reported an increased relative risk of sudden unexpected death within seven days of administration of a hexavalent vaccine, particularly after the first dose.
Parents deserve more than reassurances. They deserve answers, thorough investigations and transparency about the evidence. When an infant dies following vaccination, the response must be to investigate—not dismiss the parents’ concerns.
67 Infant Deaths: What Does the Manufacturer Report Show?
A 2025 review SIDS and Vaccination Risks: A Critical Review discusses a 2011 GlaxoSmithKline safety report involving 67 infant deaths reported following the Infanrix hexa vaccine.
According to the review, 42 deaths occurred within three days, 60 within seven days and 65 within ten days. The manufacturer reportedly concluded that the deaths did not exceed expected background incidence. But that conclusion cannot be independently evaluated from the timing figures alone. The original report, its methodology and the underlying data matter. How were expected deaths calculated, and what information was available about each case? Those are legitimate questions when infant deaths are being reviewed.
A Controversial Study Was Removed in 2026
In 2021, researcher Neil Z. Miller published an analysis of VAERS reports and the medical literature on vaccines and sudden infant death. In June 2026, Toxicology Reports removed the paper, citing serious methodological concerns. Miller disputes the removal.
The removal of a controversial paper does not settle the broader question of vaccine safety. It makes transparency more important. The original analysis, the objections raised against it and the journal's reasons for removing it should all be available for scrutiny. Parents should not be expected to accept a conclusion simply because a journal has reached it—or because a researcher disputes it.
What Can Adverse-Event Reports Tell Us?
The U.S. Vaccine Adverse Event Reporting System (VAERS), operated by the CDC and FDA, collects reports of health events occurring after vaccination.
While these reports identify potential safety signals, they do not establish causation or determine how frequently an event occurs. A report is a reason to investigate—not proof that a vaccine caused a death. The public can search reports through OpenVAERS.
Individual reports illustrate the serious events documented in VAERS. The following four reports are just a small sample of infant deaths reported after vaccination: VAERS ID 430811, involving a male infant whose death was reported hours after vaccination; ID 356473, involving a female infant with SUID/SIDS reported two days after vaccination; ID 873474, involving a male infant with cardiac arrest and death; and ID 2870251, involving a female infant with SIDS reported two days after vaccination.
These reports do not establish what caused each death, but they document tragic events and raise questions that deserve answers.
- What investigations followed?
- Were the circumstances of each death examined?
- Where can families find the findings?
Recording an adverse event is only the first step; transparent follow-up is essential.
Every Parent Deserves Answers. Help Us Keep Asking.
No parent should have to navigate the devastating loss of a baby while struggling to get answers. And no family should feel that difficult questions about their child’s health are unwelcome.
Someone has to keep asking those questions. Someone has to bring important research to light, challenge gaps in safety monitoring and make sure parents have access to information they need to advocate for their children.
That’s why Moms Across America does this work. But we cannot do it without the support of people who believe parents deserve answers and children’s health must come first.
