	Dosage	Timing (before/after vaccination)	Control	Population	Vaccine Type	Outcome	Citation
Fruits and vegetables	≥ 5 portions of fruits and vegetables per day	16 weeks with vaccination at 12 weeks	≤ 2 portions per day	65-85 years n=83	Pneumococcal Tetanus	Significantly improved antibody response to pneumococcal but not tetanus vaccines.a	Gibson et al32
Dairy	5g whey protein TID 15g total daily dose	4 weeks before and 4 weeks after vaccination	5g low isoflavone soy protein TID	60+ years n=17	Pneumococcal	Improved antibody response to the majority of strains and to all four more virulent strains.a	Freeman et al33
Dairy	6g UV-treated raw milk powder BID 12g total daily dose	4 weeks before and 4 weeks after vaccination	6g/d low isoflavone soy protein BID	63-94 years n=21	DTaP	Significantly improved antibody to tetanus but not other vaccines.a	Schaefer et al34
