A study of 1.47 million Florida adults by MIT’s Retsef Levi and Surgeon General Joseph Ladapo finds significantly higher all-cause mortality after Pfizer vaccination compared to Moderna

A new study of 1.47 million Florida adults by MIT’s Retsef Levi and Surgeon General Joseph Ladapo finds significantly higher all-cause, cardiovascular, and COVID-19 mortality after Pfizer vaccination.

The study titled “Twelve-Month All-Cause Mortality after Initial COVID-19 Vaccination with Pfizer-BioNTech or mRNA-1273 among Adults Living in Florida” was just uploaded to the MedRxiv preprint server. This study was headed by MIT Professor Retsef Levi, with Florida Surgeon General Dr. Joseph Ladapo serving as senior author:

Study Overview

  • Population: 1,470,100 noninstitutionalized Florida adults (735,050 Pfizer recipients and 735,050 Moderna recipients).
  • Intervention: Two doses of either:
    • BNT162b2 (Pfizer-BioNTech)
    • mRNA-1273 (Moderna)
  • Follow-up Duration: 12 months after second dose.
  • Comparison: Head-to-head between Pfizer vs. Moderna recipients.
  • Main Outcomes:
    • All-cause mortality
    • Cardiovascular mortality
    • COVID-19 mortality
    • Non-COVID-19 mortality

All-cause mortality

Pfizer recipients had a significantly higher 12-month all-cause death rate than Moderna recipients — about 37% higher risk.

  • Pfizer Risk: 847.2 deaths per 100,000 people
  • Moderna Risk: 617.9 deaths per 100,000 people
  • Risk Difference:
    ➔ +229.2 deaths per 100,000 (Pfizer excess)
  • Risk Ratio (RR):
    ➔ 1.37 (i.e., 37% higher mortality risk with Pfizer)
  • Odds Ratio (Adjusted):
    ➔ 1.384 (95% CI: 1.331–1.439)

Cardiovascular mortality

Pfizer recipients had a 53% higher risk of dying from cardiovascular causes compared to Moderna recipients.

  • Pfizer Risk: 248.7 deaths per 100,000 people
  • Moderna Risk: 162.4 deaths per 100,000 people
  • Risk Difference:
    ➔ +86.3 deaths per 100,000 (Pfizer excess)
  • Risk Ratio (RR):
    ➔ 1.53 (i.e., 53% higher cardiovascular mortality risk)
  • Odds Ratio (Adjusted):
    ➔ 1.540 (95% CI: 1.431–1.657)

COVID-19 mortality

Pfizer recipients had nearly double the risk of COVID-19 death compared to Moderna recipients.

  • Pfizer Risk: 55.5 deaths per 100,000 people
  • Moderna Risk: 29.5 deaths per 100,000 people
  • Risk Difference:
    ➔ +26.0 deaths per 100,000 (Pfizer excess)
  • Risk Ratio (RR):
    ➔ 1.88 (i.e., 88% higher COVID-19 mortality risk)
  • Odds Ratio (Adjusted):
    ➔ 1.882 (95% CI: 1.596–2.220)

Non-COVID-19 mortality

Pfizer recipients faced a 35% higher risk of dying from non-COVID causes compared to Moderna recipients.

  • Pfizer Risk: 791.6 deaths per 100,000 people
  • Moderna Risk: 588.4 deaths per 100,000 people
  • Risk Difference:
    ➔ +203.3 deaths per 100,000 (Pfizer excess)
  • Risk Ratio (RR):
    ➔ 1.35 (i.e., 35% higher non-COVID mortality risk)
  • Odds Ratio (Adjusted):
    ➔ 1.356 (95% CI: 1.303–1.412)

Biological explanations

The findings of this study are surprising, given that Moderna’s mRNA-1273 vaccine contains approximately three times more mRNA (100 µg) than Pfizer’s BNT162b2 vaccine (30 µg). This suggests that the higher mortality observed among Pfizer recipients could potentially be related to higher levels of DNA contamination — an issue that has been consistently reported worldwide:

The paper hypothesizes differences between Pfizer and Moderna may be due to:

  • Different lipid nanoparticle compositions
  • Differences in manufacturing, biodistribution, or storage conditions

Final conclusion

Florida adults who received Pfizer’s BNT162b2 vaccine had higher 12-month risks of all-cause, cardiovascular, COVID-19, and non-COVID-19 mortality compared to Moderna’s mRNA-1273 vaccine recipients.

Unfortunately, without an unvaccinated group, the study cannot determine the absolute increase in mortality risk attributable to mRNA vaccination itself. However, based on the mountain of existing evidence, it is likely that an unvaccinated cohort would have experienced much lower mortality risks. It’s also important to remember that Moderna mRNA injections are still dangerous.

As the authors conclude:

These findings are suggestive of differential non-specific effects of the BNT162b2 and mRNA-1273 COVID-19 vaccines, and potential concerning adverse effects on all-cause and cardiovascular mortality. They underscore the need to evaluate vaccines using clinical endpoints that extend beyond their targeted diseases.

New report warns Ottawa’s ‘nudge’ unit erodes democracy and public trust

Published on

Justice Centre for Constitutional Freedoms

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:

  1. Parliamentary oversight of all behavioural science uses within federal departments, ensuring elected representatives retain oversight of national policy.
  2. Public disclosure of all behavioural research conducted with taxpayer funds, creating transparency of government influence on Canadians’ beliefs and decisions.
  3. 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

Published on

From LifeSiteNews

By Calvin Freiburger

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.

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.”
