London 22nd August : The danger of myocarditis (inflammation of the heart muscle) in unvaccinated individuals after the Covid infection was at least 11 times greater than those who were diagnosed with the heart condition after receiving a booster or vaccine dose, a comprehensive analysis of more than 43 million people who are 13 and over, has been revealed.Numerous studies and reports from public health agencies including the US Centers for Disease Control and Prevention (CDC), have identified a possible link and a possible increase in the risk of myocarditis following the administration of the mRNA vaccine Covid-19, which has generated a lot of research policy, policy, and public concern.
“We discovered that for the vaccine-vaccinated Covid-19 population of England during the crucial 12 month time period of the pandemic at the time that the vaccines first were made available, the risk of myocarditis after vaccination was minimal in comparison to the chance of myocarditis following infection,” stated Martina Patone, a statistician at the University of Oxford.
“This analysis provides crucial information that can assist in guiding public health vaccination campaigns, in particular because Covid-19 vaccination is now available in several regions of the globe to cover children who are as young as six months,” Patone said in the study that was published in the journal of the American Heart Association’s peer-reviewed Circulation.
The study by Patone and his colleagues analyzed the the database of Covid-19 vaccinations available to everyone who is 13 and over who been vaccinated at the least with one dose of the University of Oxford-AstraZeneca vaccination, the Pfizer BioNTech or Moderna vaccine in the period between December 1st, 2020 and December 15, 2021.
This data set included almost 43 million people including more than 21 million who received the booster dose of any of the Covid-19 vaccines.
Six million people were tested positive for Covid-19 infections either before or after vaccination with Covid-19 in the course of study.
The database’s records were cross-referenced and compared to the national offices with information about Covid infections, hospital admissions and death certificates for the same time frame.
The study found that fewer than 3,000 patients were admitted to hospitals or died with myocarditis over the study’s one-year period.
The people who had been infected with Covid-19 prior to having received any dose of the vaccine were eleven times more likely to be at risk of developing myocarditis on days 1-28 following the positive test for Covid-19, the study found.
“It is crucial for the public to be aware that myocarditis is a rare condition and the possibility of developing myocarditis following the Covid-19 vaccine is uncommon.This risk should be weighed against the advantages of vaccinations in protecting against severe infections,” said Professor Nicholas Mills who is the Butler British Heart Foundation Chair of Cardiology at the University of Edinburgh and a co-author of the study.
It is also important to know who is at greater risk of developing myocarditis and what types of vaccinations are associated with increased risk of myocarditis Mills said.
The virus SARS-CoV-2 continues shift, and new contagious variants are emerging.
“Our hopes are that this study will provide a more thorough discussion of the risks of myocarditis caused by vaccines when viewed in comparison to the advantages of vaccination” declared co-author Julia Hippisley Cox.
