I'm somewhat biased, but here are my (non-medical) thoughts after reading through the document.
My understanding is that one of the main issues with Pfizer, and the mRNA vaccines more generally, is the risk of pericarditis or myocarditis, particularly in young men. Nov, given my experience, this was the first thing I looked for in the document. Interestingly, both pericarditis and myocarditis are reported under the immune-mediated/autoimmune category. I would be interested to know why this is the case, and why these would not be reported under the cardiovascular category. Out of a sample size of 42,086, there were 32 reports of pericarditis and 25 reports of myocarditis - 0.076% and 0.059% respectively. I would be interested to know how this compares to more recent studies, as I have not stayed up-to-date with the studies.
Now if you jump to the cardiovascular section, the most commonly reported issue was tachycardia, with 1,098 reports (2.6%). I appreciate that tachycardia is somewhat non-specific and that it can be caused by a number of other illnesses or its own symptom. This may be symantics, but my understanding that tachycardia falls within the umbrella definition of an arrhythmia, the latter of which has been reported occasionally as a side effect post vaccination. However, the pericarditis and myocarditis issues appear to have attracted the most attention (albeit still insufficient in my opinion). This has me somewhat confused, given the incidence (at least on this Pfizer document) of tachycardia is 34 to 44 times more likely than pericarditis and myocarditis respectively. The TGAs weekly safety report makes no reference to arrhythmias,
The governments vaccine side effects scheme only recognises pericarditis and myocarditis. The Product Information document makes reference to pericarditis and myocarditis (interestingly, under the cardiac category this time), but no reference to arrhythmias (including tachycardias). The governments vaccine claims scheme will not pay compensation for arrhythmias, only pericarditis or myocarditis. None of this makes sense to me.
Tachycardia has been one of my on-going and lingering symptoms since my pericarditis diagnosis. My specialists all agree it is due to my vaccine, but it has been 'diagnosed' variously as inappropriate sinus tachycardia, postural orthostatic tachycardia syndrome and a symptom of pericarditis. The distinction may be somewhat irrelevant given the treatment is largely the same for all of them, but I remain surprised that this arrrhythmia side of things is not getting spoken about. I saw a cardiology professor yesterday, and he mentioned that a major Sydney hospital is seeing 3-5 patients a week with tachycardia post vaccination that cannot be attributed to pericarditis or myocarditis.
I look forward to further documents being released.
