- The researchers identified a sequence in which mRNA vaccines prompt macrophages to release CXCL10, stimulate T cells to produce IFN-γ and cause inflammatory injury to heart-muscle cells in the models studied.
- The rare condition typically begins one to three days after vaccination and occurs in about one in 140,000 recipients after a first dose and one in 32,000 after a second, while the rate is about one in 16,750 among male recipients aged 30 or younger.
- In young male mice, blocking CXCL10 and IFN-γ lowered vaccine-induced troponin, while inhibitors reduced stress markers and partly restored beating function in engineered cardiac spheroids.
- In preclinical experiments, pretreatment with genistein prevented much of the harmful effect on cells and tissue, although the compound used was purer and more concentrated than comparable dietary supplements.
Without these vaccines, more people would have gotten sick, more people would have had severe effects and more people would have died.— Joseph Wu, MD, PhD, director of the Stanford Cardiovascular Institute, said during discussion of the study on mRNA vaccines and myocarditis.
