Sure, because the MRNA spike protein appears to be rough on the endothelium even in healthy individuals, so it's easy to see why this could be problematic for people who already have vascular damage. But there are a lot of other long covid symptoms that folks have reported improving after getting vaccinated, e.g. loss of smell.
I hate to ask - but what sort of research is available so far?
Based on the submitted paper, if it is intended to apply specifically to the long covid population, then it seems to be a reasonable comment. It did mention post-long-covid vaccinations seemed to be more harmful than helpful - something like ~15% found their long covid symptoms improved afterwards while ~20% had their symptoms worsen.
If that second sentence was intended to apply to the general population, then it's neither supported nor contradicted by the submitted paper. I don't believe it addressed risks outside of those already suffering from long covid. While it did address protection against long covid, it didn't come to a particular conclusion on the matter. It mentioned that studies on this aren't in general agreement yet, and pointed out a number of potential reasons for this, such as varying and potentially incomplete standards for discriminating between both long covid and control groups, in addition to the basic difficulties involved in keeping up with new strains.
As for other research... well that's a whole other thing.
Could you provide a link to that research ?
The frequency of the reaction mentioned in this article is around 2 in 100,000 people.
The frequency of death from covid is somewhere in the range of 1000-2000 in 100,000 people.
I'll take the vaccine odds.
> with fairly marginal protection benefits
Your source says nothing about protection benefits being marginal.
In fact, one of the author's of this research said: "What the results don’t do, she stressed, is change the fact that the data strongly support getting vaccinated against COVID-19. “Clearly, developing postvaccine myocarditis is much more rare than developing any of the complications of infection with SARS-CoV-2,” she noted." https://www.tctmd.com/news/free-spike-protein-mrna-covid-19-...
We have had that data for a while and simplifications serve no benefit. Its not early 2020 anymore, as always, as we get more accurate data, we get to adapt some strategies based on that.
edit: Not to mention the difference in strains (omicron vs delta) as well as the confidence into the different risks (under counting (detection problem) vs over counting(hospitalized/dying from vs with covid)
