Study Summary

Probiotics are viable commensal microorganisms that promote the establishment of beneficial microflora. Animal and human studies demonstrate that probiotics can enhance body's immune response to stimuli. Mayo Clinic in conjunction with Agri-King Corporation has developed a novel synbiotic called AKSB (Agri-King Synbiotic) that contains a probiotic bacterium (Enterococcus faecium, microencapsulated SF68 or Ventrux ME 30), a probiotic yeast (Saccharomyces cerevisiae, Lynside® Pro-Lay 1), and a prebiotic (fructo-oligosaccharide \[FOS\], NutraFlora®). This phase I placebo-controlled trial of AKSB in normal human volunteers, over 65 years of age, is designed to study the safety of this probiotic when patients are also receiving an influenza vaccine. If this study shows that AKSB is safe then our aim is to do a larger study to see if we can improve influenza vaccine immune response while taking the probiotic compared to placebo.

Primary Outcome

To evaluate the safety and tolerability of AKSB when administered with the influenza vaccine as compared to the influenza vaccine alone with placebo in patients ≥65 years of age.
