One really shouldn't put too much faith in the fact that this guy is an MD when it comes to his interpretation of the study he's quoting. I'm a biostatistician (or was, once upon a time, lol) and I worked with MDs on teams that submitted new drug applications to the FDA for approval. While MDs are certainly much better than the average person when it comes to interpreting data, they're far from perfect. There's a reason that statisticians are needed on those teams; there were multiple occasions where we had to correct a doc when it came to interpretation. And I suspect that the more a person is invested in a position, the greater the chance that (s)he will make an invalid inference, intentional or not.
It's pretty clear that this guy has a position he's pushing. One thing that jumped out at me before I even started the video is that he's raising money off of it. He has links to 3 sites to donate money to him, as well as selling $67 subscriptions to something. That doesn't in and of itself invalidate his analyses but it does raise flags. And after I heard his invalid inferences I became even more suspicious of his motives. I'd love to know how much money the guy made off of donations and subscriptions following the video.
Bleed previously pointed out indicators of an anti-vax stance in his other online stuff. Not only does he draw invalid inferences in the video, it's markedly notable for what it leaves out. Here's some of my observations:
The study that he references
does indicate that there may be a link between the mRNA vaccines and myocarditis. What he
doesn't mention is that the rate is extremely low, it's mostly in males younger than 20yo, and that not only were the observed cases transient, they were also milder than cases resulting from other pathologies. All of which would make myocarditis being a contributing factor in the Hamlin case less likely.
He presents absolutely no evidence that Hamlin's incident was related to covid vaccinations but based purely on speculation he infers that it was. Given the amount of disinformation and misinformation surrounding covid and the vaccines, I think Bleed was being generous when he categorized this as irresponsible.
Unless I missed it, Syed never once mentioned this direct quote from the paper he used to imply Hamlin's incident might have been associated with covid vaccination:
"These results do not alter the risk-benefit ratio favoring vaccination against COVID-19 to prevent severe clinical outcomes."
That's a very important conclusion and to me pretty damning evidence that Syed is pushing a narrative. You just don't overlook something like that.
Even before the vaccines started being administered there was evidence of negative effects on the cardiovascular system resulting from covid. No mention of this in the video, in spite of the likelihood that these seem to be much more prevalent and probably more severe than the myocardiopathy linked to covid vaccines. Here's some excerpts from a study on the effect of covid on the cardiovascular system of kids.

Intriguing new faces of Covid-19: persisting clinical symptoms and cardiac effects in children - Volume 32 Issue 7
www.cambridge.org
In this study, 121 children between the ages of 0– and 18 with Covid-19 were evaluated based on their history, blood pressure values, and electrocardiography and echocardiography results. These findings were compared with the findings of the control group which consisted of 95 healthy cases who were in the same age range as the study group and did not have Covid-19.
. . .
Statistically significant differences were found in systolic blood pressure, left ventricular ejection fraction, relative wall thickness, and tricuspid annular plane systolic excursion.
. . .
The clinical symptoms (chest and back pain, dizziness, headache, palpitation, fatigue, shortness of breath, loss of balance, coughing) of 37.2% of the cases persisted for at least 1 month after Covid-19 recovery. Statistically significant differences were found in systolic blood pressure, left ventricular ejection fraction, relative wall thickness, and tricuspid annular plane systolic excursion.

Another large study in adults (mostly older males): The COVID Heart—One Year After SARS-CoV-2 Infection, Patients Have an Array of Increased Cardiovascular Risks | Cardiology | JAMA | JAMA Network
This Medical News article discusses increased risks for cardiovascular disease outcomes 1 year after SARS-CoV-2 infection.
jamanetwork.com
The new analysis in
Nature Medicine examined a comprehensive, prespecified set of cardiovascular outcomes among patients in the US Veterans Health Administration (VHA) system who survived the first 30 days of COVID-19. The researchers estimated the risks and excess burden of cardiovascular outcomes per 1000 persons 12 months after COVID-19 using electronic medical record data from 3 large cohorts:
- 153 760 patients who used VHA services in 2019 and had a positive SARS-CoV-2 test result between March 1, 2020, and January 15, 2021
- 5 637 647 patients with no evidence of SARS-CoV-2 infection who used VHA services in 2019—the contemporary control group
- 5 859 411 prepandemic patients who used VHA services in 2017—the historical control group
. . .
At the 12-month mark, compared with the contemporary control group,
for every 1000 people, COVID-19 was associated with an
extra:
- 45.29 incidents of any prespecified cardiovascular outcome
- 23.48 incidents of major adverse cardiovascular events (MACEs), including myocardial infarction, stroke, and all-cause mortality
- 19.86 incidents of dysrhythmias, including 10.74 incidents of atrial fibrillation
- 12.72 incidents of other cardiovascular disorders including 11.61 incidents of heart failure and 3.56 incidents of nonischemic cardiomyopathy
- 9.88 incidents of thromboembolic disorders, including 5.47 incidents of pulmonary embolism and 4.18 incidents of deep vein thrombosis
- 7.28 incidents of ischemic heart disease including 5.35 incidents of acute coronary disease, 2.91 incidents of myocardial infarction, and 2.5 incidents of angina
- 5.48 incidents of cerebrovascular disorders, including 4.03 incidents of stroke
- 1.23 incidents of inflammatory disease of the heart or pericardium, including 0.98 incidents of pericarditis and 0.31 incidents of myocarditis
Because some COVID-19 vaccines may be associated with rare cases of myocarditis and pericarditis, the authors conducted analyses to remove the effect of vaccination. The
increased risk of myocarditis and pericarditis remained among people who were not vaccinated and was evident regardless of vaccination status.

“In our work, we show serious long-term cardiovascular disease consequences of COVID-19,” Al-Aly wrote. “Most of these are lifelong conditions that will affect people for a lifetime and may impact their quality of life and other health outcomes. The risks reported in our paper may appear small but given the large number of people with COVID-19 in the US and globally, these numbers will likely translate into millions of people with heart disease in the US and many more around the world.

From another study on potential covid vaccine related myocarditis. This is relevant with respect to evaluating the relative risk - benefit ratio of contracting covid vs negative effects associated with nRNA vaccines.
This descriptive study compares the effect of mRNA-based COVID-19 vaccination with BNT162b2 (Pfizer-BioNTech) vs mRNA-1273 (Moderna) on the reported cases of myocarditis in the US after each vaccination dose.
jamanetwork.com
Cases of myocarditis reported after COVID-19 vaccination were typically diagnosed within days of vaccination, whereas cases of typical viral myocarditis can often have indolent courses with symptoms sometimes present for weeks to months after a trigger if the cause is ever identified.
1 The major presenting symptoms appeared to resolve faster in cases of myocarditis after COVID-19 vaccination than in typical viral cases of myocarditis. Even though almost all individuals with cases of myocarditis were hospitalized and clinically monitored, they typically experienced symptomatic recovery after receiving only pain management. In contrast, typical viral cases of myocarditis can have a more variable clinical course. For example, up to 6% of typical viral myocarditis cases in adolescents require a heart transplant or result in mortality.

TLDR
In spite of Syed's attemt to link Hamlin's incident with covid vaccination, he presents no evidence that supports that conclusion. Yet based on the comments after the video, anti-vaxers are jumping on it to support their position like red meat throw to a pack of wolves. Syed is undoubtedly making money off the video, but I'll refrain from making a judgement as to whether that might have influenced what is obviously a narrative he wants to push.
Although small, there probably
is an increased risk of myocarditis in a cohort mostly comprised of young males. In the very small percentage of kids who experienced it, it appeared to be transient and milder than the myocarditis resulting from other causes. Even in that cohort, there appears to be a greater risk of severe health complications resulting from contracting covid than from receiving covid vaccinations. If I had a young son he'd be getting the J&J vaccine rather than an mRNA one and I'd be monitoring him very closely for a bit after the vaccination. And to be safe, probably no sports for a couple weeks after the vaccination.
There have been billions of covid vaccinations administered. The risk of severe health complications resulting from contracting covid is almost assuredly much greater than the risk of severe health complications resulting from any of the vaccines. Unfortunately, many seem to have either completely foregone making that relative risk ratio calculation or are basing it on misinformation.
Here's an analogy to illustrate the above point: Seat belts can lead to death if they become frozen and you can't get them unbuckled if your car submerges or is in an accident and catches fire. If for whatever reason
you want to be absolutely sure that never happens to you, you can guarantee that it won't by never wearing a seat belt. But I think most recognize that would be a misguided decision based on the overall risk assessment. I wish covid hadn't become so politicized that many are avoiding a similar calculation when it comes to assessing its risk.
