Second Massive Population Study Finds COVID-19 “Vaccines” Increase Risk of 6 Major Cancers
South Korea study of 8.4 million adults finds higher risks of overall, lung, prostate, thyroid, gastric, colorectal, and breast cancers — across both mRNA and viral-vector platforms.
About a month ago, the first-ever population cohort study reported increased cancer risks following COVID-19 vaccination. In Italy, nearly 300,000 residents were tracked for 30 months, showing that mRNA shots significantly increased the risk of overall cancer, breast cancer, bladder cancer, and colorectal cancer.

Now, a second—and far larger—population-based cohort study by Kim et al from South Korea has corroborated and expanded upon those findings. Drawing on a massive sample of more than 8.4 million people, this is one of the most powerful cancer-safety datasets ever analyzed.
The results are striking. After accounting for age, sex, comorbidities, income level, and prior COVID-19 infection, COVID-19 vaccination was linked to significant increases in multiple major cancers, with the signal consistent across all vaccine platforms, both sexes, and age groups:
Study Design at a Glance
- Design & data: Population-based retrospective cohort using the Korean National Health Insurance database (2021–2023).
- Population: 8,407,849 adults.
- Exposure: COVID-19 vaccination (analyzed overall and by platform: mRNA, cDNA, and heterologous schedules).
- Matching: Large-scale propensity score matching (1:4 vaccinated:unvaccinated for the main analysis; 1:2 within vaccinated for booster vs non-booster).
- Modeling: Multivariable Cox proportional hazards models (adjusted for age, sex, comorbidity index, income level, and prior COVID-19 infection), estimating hazard ratios (HRs) with 95% confidence intervals (CIs); analyses stratified by sex and age.
- Outcome window: 1-year incidence of overall and site-specific cancers post-vaccination.
Key Results — Cancers with Significant Increases (1-year follow-up)
- Overall cancer: HR 1.27 (95% CI, 1.21–1.33) → 27% higher risk of all cancers combined in vaccinated vs. unvaccinated at 1 year.
- Lung cancer: HR 1.53 (95% CI, 1.25–1.87) → 53% higher risk
- Prostate cancer: HR 1.69 (1.35–2.11) → 69% higher risk
- Thyroid cancer: HR 1.35 (1.21–1.51) → 35% higher risk
- Gastric (stomach) cancer: HR 1.34 (1.13–1.58) → 34% higher risk
- Colorectal cancer: HR 1.28 (1.12–1.47) → 28% higher risk
- Breast cancer: HR 1.20 (1.07–1.34) → 20% higher risk
Interpretation: An HR of 1.53 for lung cancer means that vaccinated individuals developed lung cancer at a rate 53% higher than matched unvaccinated peers, over the same one-year follow-up period. Similar interpretations apply to each cancer type.
By Vaccine Platform
- cDNA vaccines (AstraZeneca type): linked to higher risks of thyroid, gastric, colorectal, lung, and prostate cancers.
- Overall cancer HR 1.47 (95% CI 1.39–1.56) → 47% higher risk
- mRNA vaccines (Pfizer/Moderna): linked to higher risks of thyroid, colorectal, lung, and breast cancers.
- Overall cancer HR 1.20 (95% CI 1.14–1.26) → 20% higher risk
- Heterologous (mixed schedules): linked to higher risks of thyroid and breast cancers.
- Overall cancer HR 1.34 (95% CI 1.21–1.48) → 34% higher risk
Interpretation: The elevated cancer risks were not confined to one vaccine platform. Whether adenoviral-vector (cDNA), mRNA, or mixed schedules, each vaccine type was associated with a measurable increase in overall cancer — and each had specific cancer sites driving the signal. In other words, no vaccine technology was free of cancer risk in this dataset.
Booster-Dose Analysis
- Gastric cancer: HR 1.23 (p = 0.041) → 23% higher risk with boosters
- Pancreatic cancer: HR 2.25 (p < 0.001) → 125% higher risk with boosters
Interpretation: Booster doses were associated with notably higher risks of gastric and pancreatic cancers. For pancreatic cancer, the risk more than doubled in boosted individuals.
Overall Cancer Trends/Sex & Age Stratification
- Overall cancer: Incidence was higher in the vaccinated across every demographic group.
- Women showed the highest relative burden, with 48.4 per 10,000 vaccinated vs. 38.2 per 10,000 unvaccinated at one year.
- Elderly adults (≥75 years) carried the greatest absolute burden, at 119.9 per 10,000 vaccinated vs. 91.7 per 10,000 unvaccinated.
- Younger adults (<65 years) also experienced a clear overall increase, despite lower baseline rates.
- Site-specific patterns:
- Men: elevated risks for gastric and lung cancers
- Women: elevated risks for thyroid and colorectal cancers
- Under 65 years: stronger signals for thyroid and breast cancers
- ≥75 years: markedly higher risk of prostate cancer
Interpretation: Both the overall and site-specific results show a consistent pattern — every demographic group experienced elevated cancer risks, though the type and absolute burden varied. Women and the elderly were hit hardest, but no population segment was spared.
Taken together, the evidence is now impossible to ignore. The only two population-level cohort studies ever conducted on COVID-19 vaccination and cancer — one in Italy and one in South Korea — have both found major increases in cancer risk. The Italian study (≈300,000 people, 30-month follow-up) identified significant elevations in overall cancer, breast, bladder, and colorectal cancers. The South Korean study (8.4 million people, 1-year follow-up) confirmed and expanded these findings, documenting increased risks of overall cancer plus six site-specific cancers (lung, prostate, thyroid, gastric, colorectal, and breast).
Critically, the signal was observed across all vaccine types — both mRNA and viral-vector (cDNA) shots — and in every demographic group analyzed. In plain terms: both major COVID-19 vaccine platforms appear to be carcinogenic
With two independent national datasets converging on the same conclusion, governments, regulators, clinicians, and researchers must confront a sobering reality: nearly 70% of the global population has been injected with a carcinogenic product. The evidence demands immediate market withdrawal of these products.
At the McCullough Foundation, we are deeply investigating both the molecular mechanisms and the population-level data linking COVID-19 vaccination to cancer. We are currently preparing several new studies to expand this critical line of evidence.

New report warns Ottawa’s ‘nudge’ unit erodes democracy and public trust
The Justice Centre for Constitutional Freedoms has released a new report titled Manufacturing consent: Government behavioural engineering of Canadians, authored by veteran journalist and researcher Nigel Hannaford. The report warns that the federal government has embedded behavioural science tactics in its operations in order to shape Canadians’ beliefs, emotions, and behaviours—without transparency, debate, or consent.
The report details how the Impact and Innovation Unit (IIU) in Ottawa is increasingly using sophisticated behavioural psychology, such as “nudge theory,” and other message-testing tools to influence the behaviour of Canadians.
Modelled after the United Kingdom’s Behavioural Insights Team, the IIU was originally presented as an innocuous “innovation hub.” In practice, the report argues, it has become a mechanism for engineering public opinion to support government priorities.
With the arrival of Covid, the report explains, the IIU’s role expanded dramatically. Internal government documents reveal how the IIU worked alongside the Public Health Agency of Canada to test and design a national communications strategy aimed at increasing compliance with federal vaccination and other public health directives.
Among these strategies, the government tested fictitious news reports on thousands of Canadians to see how different emotional triggers would help reduce public anxiety about emerging reports of adverse events following immunization. These tactics were designed to help achieve at least 70 percent vaccination uptake, the target officials associated with reaching “herd immunity.”
IIU techniques included emotional framing—using fear, reassurance, or urgency to influence compliance with policies such as lockdowns, mask mandates, and vaccine requirements. The government also used message manipulation by emphasizing or omitting details to shape how Canadians interpreted adverse events after taking the Covid vaccine to make them appear less serious.
The report further explains that the government adopted its core vaccine message—“safe and effective”—before conclusive clinical or real-world data even existed. The government then continued promoting that message despite early reports of adverse reactions to the injections.
Government reliance on behavioural science tactics—tools designed to steer people’s emotions and decisions without open discussion—ultimately substituted genuine public debate with subtle behavioural conditioning, making these practices undemocratic. Instead of understanding the science first, the government focused primarily on persuading Canadians to accept its narrative. In response to these findings, the Justice Centre is calling for immediate safeguards to protect Canadians from covert psychological manipulation by their own government.
The report urges:
- Parliamentary oversight of all behavioural science uses within federal departments, ensuring elected representatives retain oversight of national policy.
- Public disclosure of all behavioural research conducted with taxpayer funds, creating transparency of government influence on Canadians’ beliefs and decisions.
- Independent ethical review of any behavioural interventions affecting public opinion or individual autonomy, ensuring accountability and informed consent.
Report author Mr. Hannaford said, “No democratic government should run psychological operations on its own citizens without oversight. If behavioural science is being used to influence public attitudes, then elected representatives—not unelected strategists—must set the boundaries.”

Major new studies link COVID shots to kidney disease, respiratory problems
From LifeSiteNews
Receiving four or more COVID shots was associated with 559% higher likelihood of cold in children, a new study found, and another one linked the shots to higher risk of renal dysfunction.
Two major new studies have been published sounding the alarm about the COVID-19 shots potentially carrying risks of not only respiratory diseases but even kidney injury.
The Washington Stand first drew attention to the studies, published in the International Journal of Infectious Diseases (IJID) and International Journal of Medical Science (IJMS), respectively.
The first examined insurance claims and vaccination records for the entire population of South Korea, filtering out cases of infection prior to the start of the outbreak for a pool of more than 39 million people. It reported that the COVID shots correlated with mixed impacts on other respiratory conditions. A “temporary decline followed by a resurgence of URI [upper respiratory infections] and common cold was observed during and after the COVID-19 pandemic,” it concluded. “In the Post-pandemic period (January 2023–September 2024), the risk of URI and common cold increased with higher COVID-19 vaccine doses,” it noted.
Children in particular, who are known to face the lowest risk from COVID itself, had dramatically higher odds of adverse events the more shots they took. Receiving four or more was associated with 559% higher likelihood of cold, 91% higher likelihood of pneumonia, 83% higher likelihood of URI, and 35% higher likelihood of tuberculosis.
The second study examined records of 2.9 million American adults, half of whom received at least one COVID shot and half of whom did not.
“COVID-19 vaccination was associated with a higher risk of subsequent renal dysfunction, including AKI [acute kidney injury] and dialysis treatment,” it found, citing 15,809 cases versus 11,081. “The cumulative incidence of renal dysfunction was significantly higher in vaccinated than in unvaccinated patients […] At the one-year follow-up, the number of deaths among vaccinated individuals was 7,693, while the number of deaths among unvaccinated individuals was 7,364.” Notably, the study did not find a difference in the “type of COVID-19 vaccine administered.”
The researchers note that this is not simply a matter of correlation, but that a causal mechanism for such results has already been indicated.
“Prior studies have indicated that COVID-19 vaccines can damage several tissues,” they explain.
“The main pathophysiological mechanism of COVID-19 vaccine-related complications involve vascular disruption. COVID-19 vaccination can induce inflammation through interleukins and the nod-like receptor family pyrin domain-containing 3, an inflammatory biomarker. In another study, thrombosis episodes were observed in patients who received different COVID-19 vaccines. Additionally, mRNA COVID-19 vaccines have been associated with the development of myocarditis and related complications […] The development of renal dysfunction can be affected by several biochemical factors [26]. In turn, AKI can increase systemic inflammation and impair the vasculature and red blood cell aggregation. Given that the mechanism underlying COVID-19 vaccine-related complications corresponds to the pathophysiology of kidney disease, we hypothesized that COVID-19 vaccination may cause renal dysfunction, which was supported by the results of this study.”
Launched in the final year of President Donald Trump’s first term in response to COVID-19, Operation Warp Speed (OWS) had the COVID shots ready for use in a fraction of the time any previous vaccine had ever been developed and tested. As LifeSiteNews has extensively covered, a body of evidence steadily accumulated over the following years that they failed to prevent transmission and, more importantly, carried severe risks of their own. COVID was a sticking point for many in Trump’s base, yet he doggedly refused to disavow OWS.
Since leaving office, Trump repeatedly promoted the shots as “one of the greatest achievements of mankind.” The negative reception to such comments got him to drop the subject for a while, but in July 2022, he complained that “we did so much in terms of therapeutics and a word that I’m not allowed to mention. But I’m still proud of that word, because we did that in nine months, and it was supposed to take five years to 12 years. Nobody else could have done it. But I’m not mentioning it in front of my people.”
So far, Trump’s second administration has rolled back several recommendations for the shots but not yet pulled them from the market, despite hiring several vocal critics of the COVID establishment and putting the Department of Health & Human Services under the leadership of America’s most prominent anti-vaccine activist, Robert F. Kennedy Jr. Most recently, the administration has settled on leaving the current vaccines optional but not supporting work to develop successors.
In early August, Kennedy announced the government would be “winding down” almost $500 million worth of mRNA vaccine projects and rejecting future exploration of the technology in favor of more conventional vaccines. Last week, HHS revoked emergency use authorizations (EUA) for the COVID shots, which were used to justify the long-since-rescinded mandates and sidestep other procedural hurdles, and in its place issued “marketing authorization” for those who meet a minimum risk threshold for the following mRNA vaccines: Moderna (6+ months), Pfizer (5+), and Novavax (12+).
“These vaccines are available for all patients who choose them after consulting with their doctors,” Kennedy said, making good on his pledge to “end COVID vaccine mandates, keep vaccines available to people who want them, especially the vulnerable, demand placebo-controlled trials from companies,” and “end the emergency.”
