I agree with you that measuring precisely whether the vaccine was beneficial for 15 year olds or not is difficult.
However, at the same time we have people in sibling comments claiming to know multiple people with conditions ranging from changes to their menstrual cycle to death. This can't possibly be related to the vaccine at anything like the rate people are for some reason inclined to believe.
Personally I found the effects from the 3rd booster almost as bad as COVID itself so I'm unlikely to get another unless there is a compelling reason.
