Corona vaccine: The risk of myocardial infarction is underestimated

  • FromPamela Dorhaffer

    To the end

The risk of heart attack after MRNA vaccination seems to be higher than previously thought, especially in adolescents and young adults.

FRANKFURD – The country’s health ministry has announced on its website on Friday that the MRNA vaccine from American manufacturer Moderna has not been used in Iceland since Friday. In Sweden and Finland, the corona vaccine is no longer given to men under the age of 30, and to young people under the age of 18 in Norway and Denmark. In Great Britain, Hong Kong and Norway, according to the “New York Times”, there are considerations for administering the MRNA vaccine to a limited extent only to teenagers from Beyonc / Pfizer first – specifically: give only a single dose and not a double vaccine.

As these steps are detailed, there is a common background: heart attack, inflammation of the heart muscle, after MRNA vaccination against it Corona virus Even more so than previously thought, especially among male adolescents and young adults – although this problem is a rare occurrence.

Moderna’s vaccine, the brand name Spikewax, is particularly susceptible, and to a lesser extent Bioneck / Pfizer from Carminati. This is indicated by numerous studies published in the New England Journal of Medicine, such as the work of Israel, the Canadian Health Commission’s Public Health Ontario and the previously unpublished “Nordic Research” from Scandinavia.

Corona: Iceland has discontinued the use of the modernna vaccine

Reuters news agency quotes Mika Salminen, director of the Finnish health agency, as saying that the “Nordic study” found that men under the age of 30 who were vaccinated with Spikevax had a slightly higher risk of heart attack. The study is expected to be published in a few weeks and is already available for European Pharmaceuticals Agency Ema.

Medical film

Heart attack Pericarditis is an inflammatory disease of the heart muscle that affects the pericardium around the heart.

Trigger Mostly viruses. The protective cells of the immune system can damage tissues.

Symptoms Often unspecified. Both diseases manifest in fatigue, weakness, shortness of breath, palpitations and heart pain.

A complete cure According to the Heart Foundation, 70 percent of cases can be expected. Long-term effects may include cardiac arrhythmia or, more rarely, heart failure. Pam

Iceland justifies the early complete suspension of the modern vaccine with an overall increase in heart attack and pericarditis (inflammation of the pericardium). In Iceland, people vaccinated with the Johnson & Johnson single-dose vaccine received only an additional dose of the modern vaccine.

(Background The Johnson & Johnson vaccine lacks adequate protection against the delta variant, so the German Standing Vaccine Commission now recommends a second vaccine with the MRNA vaccine.)

Corona vaccine: Inflammation of the heart muscle usually occurs more often than expected

Already available reports from Israel and Canada have concluded that myocardial infarction occurs very rarely after covit vaccine with an MRNA vaccine, but it usually occurs more often than expected. In most cases, about 70 percent had the problem within a few days of the second dose.

There is agreement that young men, adolescents and young adults in particular are more severely affected (they are in about 80 percent of cases) than women and young women. However, the reasons for this gender inequality are not yet known.

In the Israeli study, most cases occurred between the ages of 16 and 19, while those aged 18 to 24 were the most at risk, according to a report from Canada. However, the two studies can only be compared to a certain extent because only the Biontech / Pfizer vaccine was used in Israel. In Canadian work, the risk of heart attack is compared according to Carminati and Spikewax.

Inflammation of the heart muscle after corona vaccination: “twice the risk”

The Ontario Public Health Report from December 13, 2020 to August 7, 2021 recorded 263.2 cases of the most affected age group, ranging in age from 18 to 24 years. At Biontech / Pfizer, this is 37.4 cases per million doses.

The period from December 2020 to May 2021 was considered for the study from Israel entitled “Myocarditis after BND162B2 MRNA vaccine against Govit-19”, of which about five million were vaccinated. The Israeli Ministry of Health recorded 136 cases of “confirmed or possible heart attack” near the vaccine. This is “twice the risk of those who are not vaccinated”.

Often mild courses with myocardial infarction after corona vaccination

Within 21 days of the second vaccination, one in 6637 men and one in 99,853 women between the ages of 16 and 19 will have a “definite or possible” heart attack. In three out of four cases, myocardial infarction is said to be mild.

Why the vaccine from Moderna leads to more heart muscle inflammation than Biontech / Pfizer, but has not yet been proven: Spikevax contains 100 micrograms of mRNA per dose, Corminaty 30 micrograms. Since the combination of the two vaccines is not the same, it is not so easy to compare – even if the assumption that something should be done for this amount is obvious.

In the “plus side” for Moderna, it is said that the protective effect of the vaccine lasts longer than other vaccines. Inflammation of the heart muscle after vaccination was seen before the corona, but not often. Covit-19, like influenza, can also lead to heart attack. (Pamela Dorheffer)
