Cases of myocarditis after mRna Covid vaccines. According to the American Heart Association (Aha) and the American Stroke Association (Asa), the benefits of Covid vaccination “with Pfizer / BioNTech and Moderna mRna vaccines” vastly outweigh the rare and possible risk of heart complications. including myocarditis “about which the American CDCs have alerted health professionals in recent days.” We strongly urge all adults and children aged 12 years or older to undergo anti-Covid vaccination as soon as possible – reads a note – The evidence continues to indicate that Covid-19 vaccines are nearly 100% effective in preventing deaths and hospitalizations caused by Sars-CoV-2 infection “.
At the end of last week – explain Aha and Asa – the CDC warned health professionals about the fact that they are monitoring the data collected through the Vaccine Adverse Events Reporting System (Vaers) and the Vaccine Safety Datalink (Vsd), relating to cases of young adults who develop a rare myocarditis-related cardiac complication after receiving a Pfizer-BioNTech or Moderna anti-Covid vaccine. In particular, the Covid-19 Vaccine Safety Technical Work Group (Vast) of the Advisory Committee on Immunization Practices (Acip) of the CDC is examining “several dozen cases of myocarditis reported in adolescents and young adults” after vaccination. Effects that “typically appear within 4 days of administration”, which were recorded “in males more often than in females, and after the second dose more frequently than after the first”.
Possible adverse events about which cardiologists reassure, confirming precisely that the benefits of the injection-shield far outweigh the risks. The cause-effect link is also still to be clarified: “Myocarditis is usually the result of a viral infection – the experts recall – and it has yet to be determined whether these cases have any correlation with the administration of the Covid-19 vaccine, especially because the anti-Covid vaccines authorized in the United States do not contain live viruses “.
“We remain confident that the benefits of vaccination far outweigh its very limited and rare risks,” write Aha and Asa. Still, “the risks of vaccination are also much lower than those of Covid-19 infection, with its potentially fatal consequences and possible long-term health damage, including myocarditis itself”.
Vaccination against Covid with mRna vaccines therefore remains recommended to everyone, “including specifically people with cardiovascular risk factors such as hypertension, obesity and type 2 diabetes – the US cardiologists point out – those with heart disease and survivors of heart attack and stroke. “, categories that run a” risk of adverse outcome caused by the virus much greater than that possibly related to the vaccine “.
“We encourage everyone to stay in touch with their doctor and seek immediate assistance if, in the weeks following vaccination against Covid-19, they experience any of these symptoms: chest pain including sudden, sharp and excruciating pain – the specialists list – difficulty breathing or shortness of breath; abnormal heartbeat; severe headache; blurred vision; fainting or loss of consciousness; weakness or sensory changes; confusion or difficulty speaking; seizures; unexplained abdominal pain; pain or swelling in the legs “.
