Japanese study finds ‘significant increases’ in cancer deaths after third mRNA COVID doses

From LifeSiteNews
Cancer deaths started rising again in Japan in 2021, and one study concludes it ‘may be attributable to several mechanisms’ of the mRNA-based COVID vaccines.
A new study has found “statistically significant increases” in cancer deaths after taking a third dose of mRNA-based COVID-19 vaccines, according to a Japanese study published April 8 in the journal Cureus.
The study looked at age-adjusted mortality rates for multiple types of cancers from 2020 to 2022 in Japanese government data. “No significant excess mortality was observed during the first year of the pandemic (2020),” it says. “However, some excess cancer mortalities were observed in 2021 after mass vaccination with the first and second vaccine doses, and significant excess mortalities were observed for all cancers and some specific types of cancer (including ovarian cancer, leukemia, prostate cancer, lip/oral/pharyngeal cancer, pancreatic cancer, and breast cancer) after mass vaccination with the third dose in 2022.”
Notably, the rollout of the COVID vaccines coincided with an interruption and slowing of declines in cancer mortality rates that had been observed across all age groups over the span of the preceding decade. Third mRNA doses correlated with “significant excess mortalities” of all cancers, including breast, prostate, and ovarian cancer as well as leukemia. Almost all of the COVID vaccines at issue were mRNA-based, with 78% of those being from Pfizer and 22% from Moderna.
“For all cancers, we estimated the excess mortalities to be -0.4% (-0.9, 0.1), 1.1% (0.5, 1.8), and 2.1% (1.4, 2.8), respectively, indicating no excess in 2020 and statistically significant increases in 2021 and especially in 2022,” the authors write.
Changes in 2020 can be attributed to the height of the lockdowns forcing delays and cancellations of surgeries and other cancer treatments, but the researchers note several potential causal links between the vaccines and cancer deaths in 2021 and beyond.
“Some studies have shown that type I interferon (INF) responses, which play an essential role in cancer immunosurveillance, are suppressed after SARS-CoV-2 mRNA-LNP vaccination,” they write.
“SARS-CoV-2 vaccine has been shown to cause immunosuppression and lead to the reactivation of latent viruses such as varicella-zoster virus (VZV, human herpesvirus 3; HHV3) or human herpesvirus 8 (HHV8) in some cases,” the add. “These phenomena could also help explain the excess deaths from lip/oral/pharyngeal cancer in 2022 when mass vaccination with third and later doses was underway.”
The researchers conclude that “[t]hese particularly marked increases in mortality rates of these ERα-sensitive cancers may be attributable to several mechanisms of the mRNA-LNP vaccination rather than COVID-19 infection itself or reduced cancer care due to the lockdown. The significance of this possibility warrants further studies.”
“I have long suspected a cancer link to the vaccines just based on the science of immunology,” MIT researcher Stephanie Seneff told The Epoch Times in response to the study. “What I think is happening, broadly speaking, is that the vaccine is causing impairment of the innate immune response, which leads to an increased susceptibility to any infection, increased autoimmune disease, and accelerated cancer progression.”
A significant body of evidence links significant risks to the COVID vaccines, which were developed and reviewed in a fraction of the time vaccines usually take under former President Donald Trump’s Operation Warp Speed initiative. Among it, the federal Vaccine Adverse Event Reporting System (VAERS) reports 37,382 deaths, 215,734 hospitalizations, 21,616 heart attacks, and 28,299 myocarditis and pericarditis cases as of March 29, among other ailments. U.S. Centers for Disease Control & Prevention (CDC) researchers have recognized a “high verification rate of reports of myocarditis to VAERS after mRNA-based COVID-19 vaccination,” leading to the conclusion that “under-reporting is more likely” than over-reporting).
In 2021, Project Veritas shed light on some of the reasons for such under-reporting with undercover video from inside Phoenix Indian Medical Center, a facility run under the U.S. Department of Health & Human Services’ Indian Health Service program, in which emergency room physician Dr. Maria Gonzales laments that myocarditis cases go unreported “because they want to shove it under the mat,” and nurse Deanna Paris attests to seeing “a lot” of people who “got sick from the side effects” of the COVID shots, but “nobody” is reporting them to VAERS “because it takes over a half hour to write the damn thing.”
An analysis of 99 million people across eight countries published February in the journal Vaccine–the largest analysis to date–“observed significantly higher risks of myocarditis following the first, second and third doses” of mRNA-based COVID vaccines, as well as signs of increased risk of “pericarditis, Guillain-Barré syndrome, and cerebral venous sinus thrombosis,” and other “potential safety signals that require further investigation.” Earlier this month, the CDC was forced to release by court order 780,000 previously undisclosed reports of serious adverse reactions.
In Florida, a grand jury impaneled by Republican Gov. Ron DeSantis is currently investigating the manufacture and rollout of the COVID vaccines. In February, it released its first interim report on the underlying justification for Operation Warp Speed, which determined that lockdowns did more harm than good, that masks were ineffective at stopping COVID transmission, that COVID was “statistically almost harmless” to children and most adults, and that it is “highly likely” that COVID hospitalization numbers were inflated. The grand jury’s report on the vaccines themselves is highly anticipated.

Nearly Half of “COVID-19 Deaths” Were Not Due to COVID-19 – Scientific Reports Journal

Nicolas Hulscher, MPH
45.3% of “COVID-19 deaths” in Greece had no symptoms — exposing the coordinated PSYOP deployed to maximize fear and enforce mass compliance with draconian control measures.
The study titled “Deaths “due to” COVID-19 and deaths “with” COVID-19 during the Omicron variant surge, among hospitalized patients in seven tertiary-care hospitals, Athens, Greece” was just published in the journal Scientific Reports:
Abstract
In Greek hospitals, all deaths with a positive SARS-CoV-2 test are counted as COVID-19 deaths. Our aim was to investigate whether COVID-19 was the primary cause of death, a contributing cause of death or not-related to death amongst patients who died in hospitals during the Omicron surge and were registered as COVID-19 deaths. Additionally, we aimed to analyze the factors associated with the classification of these deaths. We retrospectively re-viewed all in-hospital deaths, that were reported as COVID-19 deaths, in 7 hospitals, serving Athens, Greece, from January 1, 2022, until August 31, 2022. We retrieved clinical and laboratory data from patient records. Each death reported as COVID-19 death was characterized as: (A) death “due to” COVID-19, or (B) death “with” COVID-19. We reviewed 530 in-hospital deaths, classified as COVID-19 deaths (52.4% males; mean age 81.7 ± 11.1 years). We categorized 290 (54.7%) deaths as attributable or related to COVID-19 and in 240 (45.3%) deaths unrelated to COVID-19. In multivariable analysis The two groups differed significantly in age (83.6 ± 9.8 vs. 79.9 ± 11.8, p = 0.016), immunosuppression history (11% vs. 18.8%, p = 0.027), history of liver disease (1.4% vs. 8.4%, p = 0.047) and the presence of COVID-19 symptoms (p < 0.001). Hospital stay was greater in persons dying from non-COVID-19 related causes. Among 530 in-hospital deaths, registered as COVID-19 deaths, in seven hospitals in Athens during the Omicron wave, 240 (45.28%) were reassessed as not directly attributable to COVID-19. Accuracy in defining the cause of death during the COVID-19 pandemic is of paramount importance for surveillance and intervention purposes.
Key Findings:
Massive Overcounting of COVID-19 Deaths
- Out of 530 hospital deaths registered as COVID-19 deaths, only 290 (54.7%) were actually caused by COVID-19.
- 240 deaths (45.3%) were found to be completely unrelated to COVID-19 — patients died with a positive PCR test, but showed no symptoms, required no COVID-specific treatment, and died of clearly unrelated causes.
Death Certificate Inaccuracy
- Of the 204 certificates listing COVID-19 as the direct cause of death, only 132 (64.7%) were confirmed as such after clinical review.
- Of the 324 certificates listing COVID-19 as a contributing factor, only 86 (26.5%) were found to be truly related.
Hospital-Acquired Infections Misclassified
- Patients infected during hospitalization were significantly more likely to be misclassified as COVID-19 deaths (OR: 2.3, p = 0.001).
Younger Age and Severe Comorbidities Associated with Misclassification
- Patients who died “with” COVID-19 were younger, more likely to be immunosuppressed, have end-stage liver disease, or be admitted for other causes.
Symptoms and Treatments Differed Sharply
Patients who died “due to” COVID-19 were more likely to:
- Exhibit classic symptoms: hypoxia (44.1%), shortness of breath, fever, and cough
- Require oxygen support (93.4% vs. 66.9%) and receive COVID-specific therapies:
- Remdesivir (5-day course: 61.9% vs. 35.2%)
- Dexamethasone (81.7% vs. 40.7%)
Study Strengths
This study went far beyond death certificate coding, implementing a rigorous, multi-source clinical audit:
- Full medical chart reviews: Included physician notes, lab data, imaging, and treatment records.
- Attending physician interviews: Structured questionnaires captured real-time clinical insights from those who treated the patients.
- Dual independent expert assessments: Two experienced infectious disease specialists (each with >2,500 COVID cases) reviewed each case independently for classification accuracy.
This study found that nearly half of all registered COVID-19 deaths during the Omicron wave in Greece were misclassified, with no clinical evidence linking them to COVID-19 as the true cause. Given that similar death coding practices were employed across Western nations, it is reasonable to conclude that COVID-19 death counts were artificially inflated to a comparable degree elsewhere.
This drastic inflation of death counts aligns with what many now understand to be a coordinated psychological operation (PSYOP)—designed to instill fear and maximize compliance with draconian pandemic measures such as lockdowns, mask mandates, and mass mRNA injection campaigns.
It is this weaponization of fear that has prompted criminal referrals in seven U.S. states, triggering active criminal investigations into top COVID-19 officials for terrorism, murder and racketeering:

2025 Federal Election
Before the Vote: Ask Who’s Defending Our Health

From the World Council for Health Canada
The health of Canadians has been compromised by government-mandated COVID-19 injections. The upcoming federal election is an opportunity to demand change and accountability. As you decide which candidate or party is most committed to defending the health of yourself and your family, please consider the following:
The Injections Were Never What They Claimed
The Canadian government successfully mandated the COVID-19 injections by labeling them “safe and effective vaccines.” These products are still being promoted and administered across the country. However, the truth is:
- They are not vaccines: Click Here
- They are not safe: Click Here
- They do not prevent infection or transmission.
- Evidence shows they increase the risk of COVID-19 disease and death: Click Here
These Products Contain Multiple Mechanisms of Harm
- They cause injury through multiple biological mechanisms: Click Here
- They have surpassed all vaccines in recorded history—for all infections, for all of the past thirty years combined—in causing deaths and injuries: Click Here
- They are chemically contaminated and adulterated with DNA: Click Here
- In Pfizer’s case, fraud is evident: the DNA contamination includes genetic engineering tools derived from the SV40 virus, associated with cancer risks: Click Here
This Election, We Must Demand Accountability
Insist that to have your vote, candidates must:
- Denounce the COVID-19 “vaccines.”
- Support a full halt to their manufacturing and administration.
- Uphold informed consent, scientific integrity, and bodily autonomy.
Your voice is important. Use it to reject censorship, harm, and medical coercion.
