Research involved 777 employees.
QUICK FACTS:
- In a new Swiss study published in the European Journal of Heart Failure, researchers found that 1 in 35 healthcare workers at a Swiss hospital showed signs of heart damage since being vaccinated with Moderna’s mRNA COVID-19 booster vaccine.
- The study sought to determine whether heart damage post-vaccine is sex-specific.
- The group experiencing vaccine adverse side effects was followed for about a month and more than half of the individuals reported signs of subclinical heart damage.
- Those involved in the study included 777 employees at the University Hospital Basel, 540 females and 237 males.
- “mRNA-1273 booster vaccination-associated elevation of markers of myocardial injury occurred in about one out of 35 persons (2.8%), a greater incidence than estimated in meta-analyses of hospitalized cases with myocarditis (estimated incidence 0.0035%) after the second vaccination,” the study states.
- Researchers found that myocardial injury occurred more frequently in women (20 cases) than in men (2 cases).
- The study drew upon findings from other studies to corroborate their conclusions, the researchers noting, “The main finding of this study, that subclinical mRNA vaccine-associated myocardial injury is much more common than estimated based on passive surveillance, has been confirmed and generalized in these complimentary cohorts of slightly older health care workers in Israel and adolescents in Thailand.”
- The study concluded that “mRNA-1273 vaccine-associated myocardial injury was more common than previously thought, being mild and transient, and more frequent in women versus men.”
STATEMENT FROM LEAD RESEARCHER:
- University Hospital Basel Professor Christian Muller said in a statement, “Our question was how often damage to the cardiac muscle cells actually occurs after the Covid-19 booster,” given that most myocarditis research is only observed in the most severe cases.
- “In order to answer this question, we measured a marker called cardiac troponin in the blood of employees of the University Hospital three days after the booster vaccination,” he continued. “If the level of cardiac troponin rises above the normal range, this is an indication of damage to cardiac muscle cells.”
- The professor noted that heart muscle cell damage is seen in about 3% of vaccinated individuals.
- Muller added, “According to current knowledge, the cardiac muscle can’t regenerate, or only to a very limited degree at best. So it’s possible that repeated booster vaccinations every year could cause moderate damage to the heart muscle cells,” noting that heart damage may also occur due to exposure to infections such as COVID-19 or the flu.
- He admitted that doctors and scientists do not “yet know the mechanism for how exactly the booster vaccine damages the heart muscle cells,” explaining that the “ball is back in the court of the vaccine manufacturers.”
- “When carrying out safety checks on booster vaccinations in future, they’ll also have to take the phenomenon of damage to the cardiac muscle cells into account,” he said.
BACKGROUND:
- American Faith reported that the U.S. military admitted there has been an increase in myocarditis cases since the COVID-19 vaccine rollout.
- Comparing myocarditis cases in 2021 with the average amount between 2016 to 2020, there was a 151% percent increase, with 275 cases in 2021.
- Dr. Peter McCullogh stated the increased myocarditis cases in 2021 was “most likely due to ill-advised COVID-19 vaccination,” drawing upon a study from Israel for evidence.
