Low Myocardial Risk Associated with Covid Vaccines
My Medium article today will be updating the information via MHRA’s Yellow Card Scheme for reported Myocarditis cases, please note that reported cases within self-reporting systems such as VAERS and/or the Yellow Card Scheme do NOT infer causality with a vaccine. Self-reporting systems should not be used as evidence to state a vaccine has caused X or Y, as this is not what these systems are designed for. So then, without further ado, let’s get into the article.
➡️ What is myocarditis?
According to Healthline — “Myocarditis is a disease marked by the inflammation of the heart muscle known as the myocardium — the muscular layer of the heart wall.” 
➡️ MHRA Reported Data
Myocarditis data are included up until 16th March 2022 with 756 reported cases of myocarditis following use of the Pfizer/BioNTech vaccine and 221 reports of myocarditis following use of the AstraZeneca vaccine respectively. Out of these reported cases for both vaccines, 4 fatal cases for Pfizer and 4 fatal cases for AstraZeneca, which is a very positive outlook to the conclusion, which shows us there’s a very low rate of fatal cases. 
💥 The breakdown of data via maths
- 49,100,000 total 1st and 2nd doses have been administered of the AZ vaccine.
- 221 reported cases of myocarditis with the AstraZeneca vaccine.
The chance of myocarditis from reported cases vs doses administered equates to 0.0004%.
Reported cases equate to 1 in every 222,171 vaccine doses.
- 51,100,000 total 1st and 2nd doses have been administered of the Pfizer vaccine.
- 756 reported cases of myocarditis with the Pfizer vaccine.
The chance of myocarditis from reported cases vs doses administered equates to 0.001%
Reported cases equate to 1 in every 65,592 vaccine doses.
Please note, these datasets don’t include third doses or booster dosages for either of the vaccines, so the risk of getting a myocardial event is drastically lower.
➡️ Myocarditis science studies
One study from the Nature science journal  showed us that the risk of myocardial events that happened out of 38,615,491 vaccinated individuals included in the study 1,615 (0.004%) was admitted to hospital with, or died from, myocarditis (again causal evidence would be needed with the vaccine on patient death), 397 (0.001%) of these occurred in the 1–28 days post any dose of vaccine. This highlights a very, very small risk of fatal cases or even death in this incidence, at 0.004%.
The results from a JAMA study  are here in quotes — “Among 192 405 448 persons receiving a total of 354 100 845 mRNA-based COVID-19 vaccines during the study period, there were 1991 reports of myocarditis to VAERS and 1626 of these reports met the case definition of myocarditis.” Something else important to note from the results of this study was how many patients were discharged after the conclusion of a myocardial event “96% of persons (784/813) were hospitalized and 87% (577/661) of these had resolution of presenting symptoms by hospital discharge. “ So even after hospitalisation, 87% of the 784/813 persons came out of hospital via discharge (577/661 persons)
This is one quote from the Conclusion section via a study from the AHAJournals science journal  — “Despite rare cases of self-limited myocarditis, the benefit-risk assessment for COVID-19 vaccination shows a favourable balance for all age and sex groups; therefore, COVID-19 vaccination is currently recommended for everyone 12 years of age and older.”
We also have to think too that Covid-19 infection poses a greater risk for a myocardial event to occur than compared with vaccinations.

As we can see from UK Data as well as scientific studies, the risk of myocarditis is low, it’s a very rare side effect of the vaccines, myocarditis has more out a greater risk post-Covid-19 infection than vaccination, even after a fatal event or hospitalisation there is also very high percentage odds of fully recovering and being discharged from hospital. The benefits of getting the vaccine most certainly outweigh any small percentage risk for Covid-19 vaccination.
