From what I've read elsewhere, the child hepatitis seems to be more prevalent in the Janssen jabs. Janssen used a gastrointestinal adenovirus vector platform (Adenovirus 26) which was not supposed to be able to replicate. However, it CAN replicate AND mutate into Adenovirus F41 which IS linked to hepatitis. Lo and behold, Janssen was recently discouraged to be used.
