The Covid vaccines Moderna, Pfizer and Astra Zeneca are all said to have adverse effects on cardiovascular health. This is what emerges from several studies published in prestigious American scientific journals between April and June 2022. The point on what they underline.
All underline the interest of vaccines, but also point to its potentially harmful effects on the cardiovascular health of patients. And especially the younger ones.
Increased risk of myocarditis or pericarditis
A study conducted by The Lancet, underlines on June 11 “an increased risk of myocarditis or pericarditis in men aged 18 to 25 after a second dose of the vaccine” Moderna and Pfizer. The prestigious British journal stresses, however, that “this incidence was rare”: 411 myocarditis or pericarditis having been detected out of the more than 15,000 people aged between 18 and 64 observed by the scientists.
The Lancet also points out that “the results of the study, as well as the benefit-risk balance, continue to support vaccination with one or the other of the two messenger RNA vaccines”.
More cardiac arrests during vaccination periods
On April 28, Scientific Reports, one of the most important open-access journals on the planet, highlighted an increase “of more than 25% in the number of calls among 16-39 year olds” for cardiac arrest or cardiac syndromes. acute coronary “during the deployment of anti-Covid vaccination in Israel”.
The review also points out that the same findings were made in Germany and Scotland during the vaccination period, and that, on the other hand, no link has been established between these cardiovascular problems and Covid infections.
Astra Zeneca also targeted
If these first two studies point the finger at messenger RNA vaccines, another analysis published on June 14 Jama, the journal of the American Medical Association, highlights “an increase in the number of hospital contacts for bleeding disorders and cerebrovascular diseases, in particular for thrombocytopenia and cerebral venous thrombosis”, after vaccination by Moderna, Pfizer and especially Astra Zeneca.
