Downstream effects of the antibodies that people produce against the coronavirus spike protein may lead to myocarditis and even neurological concerns, two veteran medical researchers have written in the top medical journal in the United States.
Our immune systems produce these antibodies in response to both vaccination and natural infection with Covid. However – though the researchers do not say so explicitly, possibly because doing so would be politically untenable – spike protein antibody levels are MUCH higher following vaccination than infection. Thus the downstream response to vaccination may be more severe.
The NEJM published the short paper Wednesday in its Basic Implications of Clinical Observations series. One of the writers is an oncologist and professor at Harvard Medical School; the other is a cancer researcher who has his own lab at the University of California, Davis.
