A separate team of researchers suggest in The Lancet Gastroenterology & Hepatology that it’s possible that the affected children, many of whom are too young to be vaccinated, may have had mild or asymptomatic COVID-19 infections that went unnoticed. A theory put forward by the researchers is that lingering particles of the coronavirus in the gastrointestinal tract in these children could be priming the immune system to over-react to adenovirus-41F by producing high amounts of inflammatory proteins that then damage the liver. “We suggest that children with acute hepatitis be investigated for SARS-CoV-2 persistence in stool” and for other signals that the liver damage is happening because the spike protein of the coronavirus is a “superantigen” that over-sensitizes the immune system, the researchers said.

So they are implicating the 'rona spike protein specifically. Is that the same spike protein which all the vaxes program the body to make indefinitely?
