Primary Outcome Measures:
  • laboratory-confirmed influenza or other respiratory viral infection in participants in intervention arm of study [ Time Frame: Participants will be assessed twice weekly for symptoms and be followed for 12 months. This will begin after they have been randomized to probiotics or placebo arms of the study ] [ Designated as safety issue: No ]
    this will be confirmed on the basis of reverse transcriptase Polymerase Chain Reaction(PCR)

  • laboratory-confirmed influenza or other respiratory viral infection in participants from placebo arm of the study [ Time Frame: Participants will be assessed twice weekly for 12 months following randomization into probiotics or placebo arms of the study ] [ Designated as safety issue: No ]
    This will be confirmed on the basis of reverse transcriptase Polymerase Chain Reaction(PCR)


Secondary Outcome Measures:
  • influenza like illness [ Time Frame: Participants will be assessed twice weekly and follwed for 12 months after they have been randomized into probiotics or placebo ] [ Designated as safety issue: No ]
    influenza-like illness will be defined by the presence of fever, sore throat, and cough and will measure symptom severity

  • antimicrobial prescriptions [ Time Frame: To be reviewed at the twice weekly assessments for 12 months following randomization ] [ Designated as safety issue: No ]
    courses of antimicrobials (name, does and duration) will be recorded by research nurse using information on the medication container or by contacting the prescribing physician if necessary

  • physician visits for respiratory illness [ Time Frame: The participant's MD patient record will be reviewed for visits during the 12 months following randomization ] [ Designated as safety issue: No ]
    information will be obtained from the attending physician

  • hospitalizations for lower respiratory infection or pneumonia [ Time Frame: Patient will be asked during the twice weekly assessments about any hospitalizations, as well as consulting their MD, during the 12 months following randomization ] [ Designated as safety issue: No ]
    cause of hospitalizations will be assessed by the research nurse through interviews with the participants and reviews of hospital medical records. Deaths will be recorded using medical records
