“Damage to the heart is more common than thought after receipt of Moderna’s COVID-19 booster, a new study indicates.
One in 35 health care workers at a Swiss hospital had signs of heart injury associated with the vaccine, mRNA-1273, researchers found…
In a generally healthy population, the level would be about 1 percent, the researchers said.
The group experiencing the adverse effects was followed for only 30 days, and half still had unusually high levels of high-sensitivity cardiac troponin T, an indicator of subclinical heart damage, at follow-up.
The long-term implications of the study remain unclear as little research has tracked people over time with heart injury after messenger RNA vaccination, which is known to cause myocarditis and other forms of heart damage.
‘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,’ University Hospital Basel professor Christian Muller, a cardiologist and the lead researcher, said in a statement.”
