The cases of myocarditis and pericarditis are reported in young people who received mRNA COVID-19 vaccines.
CDC reports suggest link between mRNA COVID vaccine and myocarditis:
According to the Centers of A.U.S for Disease Control and Prevention (CDC) group says that the reports suggest a likely link between mRNA-based COVID vaccine and myocarditis in adolescents and young adults, but the vaccination benefits still outweigh any risks.
The Advisory Committee on Immunization Practices (ACIP) of CDC on Wednesday said that early data from their database shows a rate of 4.4 heart inflammation reported cases per million first doses given of any mRNA vaccine in the 21 days. That rate now reached to 12.6 reported cases per million second doses.
Dr. Matt Daly said, “nothing is absolutely risk-free in life”.
Dr. Matt Daly, head of the ACIP COVID-19 vaccines working group emphasized the strength of the U.S. vaccine safety monitoring system, During the presentation, he said: “However, nothing is absolutely risk-free in life, And we know from experience of decades with other vaccines that rare but serious events can occur following vaccination”.
Myopericarditis is a condition where both myocarditis and pericarditis are present.
FDA to add detailed warning about the risk of heart inflammation.
The representative of the FDA liaison, Doran Fink, MD, Ph.D., said the group will add a detailed warning about the risk of myocarditis or pericarditis for those who vaccinate. that states “the events of myocarditis or pericarditis have occurred in some recipients from dose 2, the symptoms were several days to a week” and based on the data, “most cases had a resolution for the symptoms.”
The warning would also includes a advise to “seek medical attention those are experiencing these symptoms”and it state the information on long-term sequelae with the limited condition.
The staff of CDC said that they would also update their fact sheets of vaccine with more comprehensive information soon.
Maybe mRNA vaccine is a new trigger mechanism is still unclear:
The Centers of A.U.S for Disease Control and Prevention (CDC) has been investigating the heart inflammation cases mainly in young men for several weeks and said earlier this month that they are still evaluating the risk from the condition and did not confirm a normal relationship between the heart issues and the vaccines.
Matthew Oster, MD, a member of CDC’s COVID-19 Vaccine Task Force, had done the research on cases of pericarditis and myocarditis, During the presentation he said “We do not know potential mechanisms yet.” Myocarditis is not a new disease but rare, As per the findings suggesting mRNA vaccines “may be a new trigger.”
Conditions of Myocarditis reported in various countries, including Canada:
The research found reports of heart inflammation after the vaccination in various countries including the U.S, Canada, Italy, and Israel.
the Israel health ministry said in early June that, 275 cases of myocarditis were reported In the country between December 2020 and May 2021 from five million vaccinated people.
95% of the cases were classified as mild and most patients who experienced heart inflammation only spent less than four days in the hospital.
53 myocarditis cases reported to Health Canada:
According to the latest Canadian vaccine safety data as of June 11, there have been at least 53 myocarditis or pericarditis cases reported to Health Canada or the Public Health Agency of Canada. the majority occurring after the mRNA vaccination made by Pfizer-BioNTech and Moderna.
Matthew Miller the associate professor of immunologist and McMaster University said, The rate of reported cases aren’t yet above the expected levels in Canada, that’s likely because many younger Canadians have only received their first dose of vaccination.
