Can the government present anything in a useful manner? The most important information, i.e. if the young men engaged in heavy sports right after getting the vaccine, is missing. Heavy sports is obviously also dangerous while recovering from the flu. But the disorganized chaotic government presentation doesn't give any useful information.

Be careful criticizing government on HN it will be buried in down votes by the fanatics for whatever party is currently in power.

The interesting table with absolute numbers is on page 18 of [0]. Expected and observed cases are cases of myocarditis / pericarditis here. Crude rate is the number of cases per 1 million administered doses. Use landscape mode if you are reading this from a mobile device, the table is narrow enough for that. Age group Doses Crude Expected Observed administ. rate cases cases 12–15 yrs 134,041 22.4 0–1 2 16–17 yrs 2,25…

Crude rate seems to be observed cases per million doses administered. So a lot more incidents than expected, but still extremely rare (0.002% of doses). Edit: missed an extra "0" in that percent, thanks for the the catch everyone who did

Thanks! It also says that in the footnote. I added it to the comment.

I think that many people who did not have heart issues before don't know what to look for or how it feels.

Personally, I did not know I had palpitations until I googled it later. Similarly, I suspect, that some kids/young adults may have had symptoms but don't report.

Earlier quoted context omitted.

I had this after COVID in April last year right at the beginning. I suspect it is an immune reaction to the virus not the vaccine itself.

But the Pfizer vaccine doesn't contain any of the virus, unless it's just the immune reaction to the spike protein that causes the problem?

Maybe having immune system working hard somehow naturally puts strain on cardiovascular systems?

Very interesting given one of the lesser known complications of covid can be myocarditis in otherwise healthy individuals with few or no other covid symptoms.

In fact, it’s likely the incidence of covid-induced myocarditis is vastly underreported given it often shows no symptoms and can only reasonably be diagnosed with a cardiac MRI which is not always widely available or advised for less-serious heart conditions.

I was diagnosed with myocarditis last year and despite a negative PCR test around the onset of symptoms (light-headedness, heart palpitations, fatigue) was strongly suspected to have contracted covid.

I was lucky enough to get my first dose of the moderna vaccine a few months back and beside a few days of increased heart palpitations I’ve had no trouble as far as I’m aware, does make me wonder about getting that second dose though.

Anecdote: I had this reaction to the 2nd dose of the Pfizer vaccine, saw a cardiologist and she mentioned that she’s been seeing this quite a bit after the second dose. Have had to lay low for a month, but it seems like the symptoms are finally passing.

Anecdote: I too experienced this reaction, albeit after the first dose.

Noticeable but not significant heart pain beginning approximately 4 hours after getting the first vaccine.

Speaking with medical professionals, they said symptoms should improve with time, and they have nearly completely across the 1.5 months since.

Unsure if worth noting, but I had very strong immune responses to both the first and second doses.

What kind of symptoms makes one go to a cardiologist? Just curious

Arrhythmias are perhaps the most specific indicators that you should see a cardiologist, but chest pain and/or shortage of breath on mild exercise could well be caused by a heart problem. These are some of the symptoms of myocarditis, among other things.

Along those lines, I am wondering how this compares to other non-SARS-CoV-2 vaccines.

But it's only been a few months since administration, will the gap between expected and actual keep growing, or will they eventually level out?
