A major new study involving millions of vaccinated people has linked Covid mRNA “vaccines” to surges in cases of severe heart disease and related deaths.
The bombshell peer-reviewed study was conducted by a team of leading South Korean researchers in collaboration with the world-renowned Cambridge University in England.
The researchers analyzed the official government health data of 3,350,855 vaccinated South Korean citizens.
The data was obtained from South Korea’s National Health Insurance Service (NHIS).
All of the subjects had received one dose of a Covid vaccine from February 2021 to March 2022.
The group was divided into two separate cohorts: Those who received an mRNA injection, and those who received a non-mRNA shot.
South Korea administered five types of COVID-19 vaccines: the Pfizer-BioNTech and Moderna mRNA shots, and the AstraZeneca, Janssen (Johnson & Johnson) and Novavax non-mRNA shots.
The study found that acute heart disease is surging among those who received one dose of a Covid mRNA vaccine.
The researchers regular levels of heart disease among the group that received non-mRNA shots.
The results of the study were published by Cambridge University and in the journal Epidemiology and Infection.
The team of researchers said the heightened risk was most pronounced among people ages 10 to 59 compared with those age 60 and older.
The study authors wanted to see if receiving a first dose of a particular type of COVID-19 vaccine was associated with developing acute heart disease within 21 days post-vaccination.
They also sought to determine if developing a COVID-19 infection within 21 days after the first vaccine dose was linked to a higher risk of acute heart disease.
To find out, they analyzed cardiac adverse events “including acute cardiac injury, acute myocarditis, acute pericarditis, cardiac arrest, and cardiac arrhythmia, in relation to vaccine type and COVID-19 within 21 days after the first vaccination date,” according to their report.
“The results revealed higher heart disease risk in individuals receiving mRNA vaccines than other types,” they wrote.
“Individuals infected by SARS-CoV-2 also exhibited significantly higher heart disease risk than those uninfected.”
However, the study authors didn’t find a statistically significant interaction between individuals’ COVID-19 infection status and the type of Covid vaccine they received.
The results mean the higher risk wasn’t contingent on the person having both a COVID-19 infection and an mRNA vaccination.
However, they did find that younger people who received mRNA vaccines had a higher heart disease risk compared to those 60 and up.
Discussing the findings of the study on his Substack, renowned cardiologist Dr. Peter McCullough said public health agencies never studied the comparative safety of the different Covid vaccine types.
There should be “investigations into why the agencies preferentially promoted mRNA vaccines despite their higher risk of cardiovascular events,” McCullough added.
The authors said their study had some limitations, however.
They only examined cardiac adverse events reported during the three weeks following the first vaccination dose, in particular.
They explained why they had to do this:
“In our analysis, an adverse event related to the vaccine was considered to be a new acute heart disease-related diagnosis occurring within 21 days of the first dose vaccination date.
“This operational definition was necessary because we lacked information on the specific association between COVID-19 vaccines and diagnostic codes in the NHIS COVID-19 database.
“Given that the recommended interval between the first and second vaccine doses for Pfizer/bioNTech was 21 days, we concentrated on infections occurring within 21 days after the initial vaccine dose.”
The researchers noted that it would have been “particularly useful” if their study could have looked at cardiac adverse events following the second dose.
Other recent studies have shown the risk of myocarditis and pericarditis to be highest after the second dose of mRNA vaccines.
They are now calling for more research into the issues.
The study follows similar research that investigated the impact of the vaccine on children’s cardiac health.
As THAIMBC News reported earlier this month, a major study involving 1.7 million children also found that heart damage only appeared in children who had received Covid mRNA vaccines.
Not a single unvaccinated child in the group suffered from heart-related problems.
In addition, the researchers note zero children from the entire group, vaccinated or unvaccinated, died from COVID-19.
Furthermore, the study found that Covid shots offered the children very little protection from the virus, with many becoming infected after just 14 to 15 weeks of receiving an injection.
The 1.7 million children observed in the study were between the ages of 5 to 15 and were registered with the UK’s National Healthcare System (NHS).
The study was conducted by a team of leading UK medical doctors, epidemiologists, biostatisticians, and public health experts led by Oxford University’s Professor Colm D Andrews.
