Summary:
- Researchers at Stanford University have discovered a potential mechanism that explains why mRNA-based COVID-19 vaccines can sometimes cause myocarditis, or inflammation of the heart muscle.
- The study found that the spike protein produced by the mRNA vaccines can directly affect the heart muscle cells, leading to inflammation and damage.
- The findings provide important insights into the rare side effect of myocarditis and could help in the development of safer and more effective mRNA vaccines in the future.
