I wonder whether the recent spate of pediatric hepatitis cases might be confined to children (who were too young to have been jabbed) being exposed to the vax or vax generated antibodies from their parents. That shouldn't be too hard to determine, by looking at whether there is any significant increase in likelihood for vaxxed parents. Although, you'd also need to account for other possible contamination sources for children, such as teachers and childcare workers. It's probably not a simple cause/effect scenario though, more likely that something relating to the jab is effecting the immune systems of children (through shedding) that increases their susceptibility to liver damage (hepatitis) from some other source, such as an adenovirus infection. It's extremely complicated and difficult to prove definitively.
