I used to, but haven’t been regular about it for several years. Is there a link between it and adult onset allergies?

  It has been proposed for at least egg allergy, since the flu shot contains egg protein and there is a plausible MoA. Some of the shots also use adjuvant 65, which contains peanut oil and it's possible the same MoA applies. Your own personal risk-reward calculation applies of course
