Myocarditis appears to be a rare occurrence, and has been observed after getting infected with Covid, vaccinated or not. Well, no vaccine is perfect and side effects are par for the course. The CDC tends to be an extremely cautious organization, which is fine. It’s part of the job.
“Most cases appear to be mild, and follow-up of cases is ongoing.
Within CDC safety monitoring systems, rates of myocarditis reports in the window following COVID-19 vaccination have not differed from expected baseline rates. However, VaST members felt that information about reports of myocarditis should be communicated to providers.”
“The benefits of COVID-19 vaccination enormously outweigh the rare, possible risk of heart-related complications, including inflammation of the heart muscle, or myocarditis. The American Heart Association/American Stroke Association, a global force for longer, healthier lives, urges all adults and children ages 12 and older in the U.S. to receive a COVID vaccine as soon as they can.”
“The American Heart Association recommends all health care professionals be aware of these very rare adverse events that may be related to a COVID-19 vaccine, including myocarditis, blood clots, low platelets, or symptoms of severe inflammation. Health care professionals should strongly consider inquiring about the timing of any recent COVID vaccination among patients presenting with these conditions, as needed, in order to provide appropriate treatment quickly.”
DALLAS, Sunday, May 23, 2021 – Late last week, the U.S. Centers for Disease Control and Prevention (CDC) alerted health care professionals that they are monitoring the Vaccine Adverse Events Reporting System (VAERS) and the Vaccine Safety Datalink (VSD)...

Myocarditis occurring after covid (and other common diseases):
“Before returning to play, the athletes underwent three noninvasive tests that tracked heart rhythms, took an ultrasound of their hearts and measured a protein in their blood that can be a signal of heart damage. Thirty athletes had abnormal test results and were referred for a cardiac MRI. Doctors diagnosed five cases of inflammatory heart disease (0.6% of the total), with three cases identified as myocarditis and two as pericarditis.”
“Myocarditis is a rare but known effect of viral infections, including those that cause the common cold, H1N1 influenza or mononucleosis. Left undiagnosed and untreated, it can cause heart damage and sudden cardiac arrest, which can be fatal.”
A recent study has revealed that out of 789 professional athletes infected with COVID-19, only five of them had inflammatory heart disease.

These numbers are well-known to the medical community, and one of the authors of the study actually addressed this:
“You could also, of course, calculate the
absolute risk reduction. That’s simply the difference in risk for someone in the treatment group versus someone in the control group. Here’s an example: Say you have 100 people who don’t get a vaccine, and you find that 10 of them catch the disease. So the baseline risk of getting it is 10%. And suppose that 100 other people get the vaccine, and only one of these gets sick. Their risk is 1%. The
absolute risk reduction (ARR) is then just 9% (10% minus 1%), because the risk was already pretty low. But the
relative risk reduction (RRR) is 90%—that reduction of 9% divided by the baseline risk of 10%.
As a commentary in
Lancet Microbe pointed out last month, even with trials on tens of thousands of people, the absolute risk reductions in Covid-19 vaccine trials are teensy-tiny—a reduction in the risk of getting severe Covid of just 1.2% for Moderna and a scant 0.84% for Pfizer. “One of the main reasons why absolute risk reduction is not shown is because of the numbers. If you say, ‘It’s 95% effective’—wow!” says Piero Olliaro, an infectious disease researcher at the University of Oxford’s Centre for Tropical Medicine and Global Health and one of the authors of the
Lancet Microbe article. “But if your absolute risk reduction is like 0.8% or whatever it was, so what?”
The key here, though, is that absolute risk reduction
does change according to how at-risk the groups of people were in the first place. This pandemic has widely varying risks across populations, and those change over time. (For example, viral variants change how infectious Covid can be, and young people’s risk of severe illness and death has changed as social policies and infection rates have fluctuated. It’s a hard problem!) I’m suggesting that this confusion, and the conflation of these two ideas, might be at the heart of some hesitance. By not being clear about the different flavors of risk and benefit for different vaccines and different people, public health experts have let doubt and dodgy personal interpretations flourish.”
They’re really very good, and they’re the only way out of the pandemic. But a tour through the numbers could bring the vaccine-hesitant into the tent.

You can apply the same to other vaccines and get similar numbers. The reason why ARR isn’t reported is because the general public will misinterpret what ARR is. I don’t think it’s really a gotcha.
