I'll challenge your hypothesis on one well known point:
Overall, vaccine reactions in the over 65 population are less common. Overall, this population has suffered the greatest mortality from the actual virus.
I do believe my reaction may have been more severe because I am younger than 65. (I just turned 52) It would make sense to me that my immune response would be more robust than an older persons.
Those who I know who had more of a reaction have been younger. My husband is 59, he had a sore arm with a low grade fever and fatigue. We did both feel 100% normal again after around 32 hours. It was a wild ride.
