MIT Professor Retsef Levi Vaccine Claims Examined!

Let’s take a look at the viral video by MIT professor Retsef Levi, who called for the immediate suspension of mRNA COVID-19 vaccines, and find out what the facts really are!


MIT Professor Retsef Levi Calls For Suspension Of mRNA Vaccines!

A video by MIT professor Retsef Levi has gone viral, after he claimed that mRNA COVID-19 vaccines were causing serious harm to young people, and called for their immediate suspension!

Here is my rough transcript of what Retsef Levi said in his viral video. It’s VERY long, so feel free to skip to the next section for the facts!

Hi, my name if Retsef Levi, and since 2006, I’m a faculty member at MIT in Cambridge, Massachusetts. I have more than 30 years experience as a practitioner and an academic in using data analytics to assess and manage risk, particularly in the context of health systems, health policies, as well as the management of safety and quality of manufacturing of biologic drugs.

MIT Professor Retsef Levi Vaccine Claims Examined!


MIT Professor Retsef Levi Vaccine Claims Examined!

You do not have to be an MIT professor like Retsef Levi to go through his claims, and discover these facts for yourself. It’s really not difficult at all. Let me show you…

Fact #1 : Retsef Levi Is Professor of Management + Operations Management

Normally, I do not like to comment on people’s credentials, as the merits of their facts and arguments should stand on their own. However, Retsef Levi made a point of mentioning his credentials, so I feel it is necessary to have a clearer picture of his credentials.

Retsef Levi is a professor of Management, as well as Operations Management at the MIT Sloan School of Management, which is a separate business school under the Massachusetts Institute of Technology (MIT).

MIT Sloan focuses on MBA, Finance, Business Analytics, Management, etc. and is separate from the MIT School of Science, where the faculty teaches and researches the hard sciences from physics and biology to computational biology and statistics.

Management and Operations Management deal with business administration practices to create the highest level of efficiency within a business organisation, which are critical in managing large corporations like Pfizer and Moderna, but would have virtually nothing to do with the actual research and development (R&D) of their products.

Fact #2 : MIT Study Did Not Prove Pfizer Vaccine Raised Heart Problems!

The first study that Retsef Levi mentioned was the one he co-authored in April 2022, which I fact checked in May 2022. In my fact check article, I pointed out these problems:

  • No clinical research was conducted on any patient. The study only “analysed” data collected by a third party – the Israel National Emergency Medical Services.
  • The study relied on call data based on initial diagnosis by responding paramedics, not the final / actual diagnosis by doctors after the patients undergo all necessary clinical and laboratory investigations at the hospital.
  • The data did not include about 50% of cardiac arrest and acute coronary syndrome cases in Israel for that period of time.
  • The data was not tied to COVID-19 infection, or COVID-19 vaccination, or even pre-existing heart problems.
  • The authors themselves pointed out that they did not establish any causal relationship between COVID-19 vaccines and heart problems.
  • The authors also pointed out that the increase in cardiac arrests and acute coronary syndrome may be caused by “other underlying causal mechanisms”.

My fact check article goes much further, but suffice to say – that MIT study did not prove that the Pfizer vaccine increased the risk of heart problems like cardiac arrests in young adults.

Fact #3 : Adverse Events of Special Interest Are Not Vaccine Side Effects!

As supporting evidence, Professor Retsef Levi shared a September 2022 article called “Serious adverse events of special interest following mRNA COVID-19 vaccination in randomized trials in adults“.

That article claimed that “secondary analysis of serious adverse events reported” in the Phase 3 trial of the Pfizer and Moderna COVID-19 vaccines showed that they were associated with significantly higher risk of serious adverse events of special interest (AESI):

  • Pfizer : 36% higher risk of AESI
  • Moderna : 6% higher risk of AESI
  • Pfizer + Moderna combined : 16% higher risk of AESI

What I don’t understand about the article is why the authors performed their “analysis” of adverse events of special interest (AESI), when they are not side effects of the vaccines!

  • The AESI list is not specific to the Pfizer or Moderna COVID-19 vaccines.
  • The AESI list includes “exposure to SARS-CoV-2”, and other viruses like Herpes, MERS, Varicella, as well as other “communicable disease”.
  • The AESI list includes manufacturing and lab test issues like “Manufacturing laboratory analytical testing issue, Manufacturing materials issue, Manufacturing production issue“.
  • The AESI list includes product supply issues like “Product availability issue, Product distribution issue, Product supply issue“.

That’s not all, but I think you catch the drift – the Adverse Events of Special Interest (AESI) list is not a list of vaccine side effects!

Fact #4 : Smallpox Vaccine Does Not Use mRNA Technology

Oddly enough, Retsef Levi referred to a 2015 US Military finding that the smallpox vaccine caused heart problems.

In this 2019 case study by the US military, the rate of myopericarditis was shown to increase by 50X after they switched from the older Dryvax smallpox vaccine, to the new ACAM2000 vaccine.

However, that new ACAM2000 smallpox vaccine does not use mRNA technology, but a single plaque-purified vaccinia virus derivative of Dryvax (NYCBH strain).

In other words – the smallpox vaccine uses a live but less dangerous virus called vaccinia, to help your body develop immunity against the smallpox virus.

Viral infections, even if they are mild, can lead to heart inflammation, so it would not be surprising if the smallpox vaccine (which uses an actual virus) can trigger heart inflammation in a small number of people.

Fact #5 : Implication Of Free Spike Protein In Vaccine Myocarditis Still Unknown

On 4 January 2023, a study published in the journal Circulation showed that 16 patients who developed myocarditis after mRNA vaccination had “markedly elevated levels of full-length spike protein” that were “unbound by antibodies”.

In contrast, no free spike proteins were detected in 45 control subjects who did not develop myocarditis after mRNA vaccination.

This is a very interesting finding, which suggests that free spike proteins (unbound by antibodies) may possibly be the cause of myocarditis in young adults who receive the mRNA vaccine. However, the implication isn’t clear because it is not known why there are free spike proteins in the first place.

The mRNA vaccines teach some of our cells to create spike proteins. Because they are expressed on the cell surface, those spike proteins do not float freely in the blood, but rather, trigger the immune system to develop antibodies that bind to them.

As the study noted, people who do not develop myocarditis after receive the mRNA vaccines do not show any free spike protein – precisely what was meant to happen.

So the implication of that finding of free spike protein is still unknown, and warrants additional research. It is, however, not evidence that the mRNA vaccines cause heart problems.

Fact #6 : Vaccine-Induced Myocarditis Can Be Confirmed

It is important to point out that vaccine-induced myocarditis can be clinically differentiated from classical myocarditis, as well as proven through histopathology.

Instead of relying on “statistical analysis” of partial data from emergency call centres, we should rely instead on proper medical diagnoses based on clinical and laboratory investigations.

That is how we can avoid prematurely claiming that people died from the COVID-19 vaccines, only for their autopsies to prove otherwise, like these cases:

Will these anti-vaccination activists apologise for lying to you? Nope! They will just move on to the next athlete tragedy…
