"..if the vaccine successfully induces an immune response, which some studies suggest may be more robust than natural exposure to the virus, then could the vaccine incite the inflammatory reaction resulting in MIS-C?
If so, would it be more frequent or severe if the immune response is greater? Couldn’t this place healthy children at risk of a severe outcome from the vaccine who had an extremely low likelihood of getting sick at all? "
