Summary:

      The study will be designed as a prospective surveillance of the immune response to seasonal
      influenza vaccination in 240 healthy children and adults ages 9 and over. Study duration will
      be 5 years, with a participant duration of 6 months. Subjects will receive a quadrivalent
      inactivated influenza vaccine, at a dose of not less than 15 ug of hemagglutinin (HA), by
      intramuscular injection in open label fashion on day 0. Blood draws will occur at baseline,
      day 7, 28 and 90. The primary objective of this study is to evaluate the relationship between
      first influenza A virus exposure (inferred by age), vaccine history, and baseline serum
      antibody response to seasonal influenza vaccine in healthy adults and children.
    

Eligibility criteria:

             dose, or frequency of medication in the last 3 months and health outcomes of the
             specific disease are considered to be within acceptable limits in the last 6 months

          3. The subject is able to understand and comply with the planned study procedures,
             including being available for all study visits

          4. The subject/parent has provided informed consent/assent prior to any study procedures

          5. Subjects who have not received seasonal flu vaccine for the current year

        Exclusion Criteria:

          1. Subject report of known hypersensitivity to allergy to components of the study vaccine
             or other components of the study vaccine

          2. Subject report of known latex allergy

          3. Subject report of a history of severe reactions following previous immunization with
             licensed or unlicensed influenza virus vaccines

          4. Subject report of a history of Guillain-Barre syndrome within 6 weeks of receipt of a
             previous influenza vaccine

          5. The subject is a female of childbearing potential who is currently pregnant or
             breastfeeding or intends to become pregnant during the study period between enrollment
             and 90 days following receipt of vaccine. Pregnancy will be determined by subject
             interview. Pregnancy testing is not done in this study since there is no increased
             risk in pregnancy

          6. The subject is immunosuppressed as a result of an underlying illness or treatment with
             immunosuppressive or cytotoxic drugs, or use of anticancer chemotherapy or radiation
             therapy within the preceding 36 months

          7. The subject has an active neoplastic disease (excluding non-melanoma skin cancer or
             prostate cancer that is stable in the absence of therapy) or a history of any
             hematological malignancy. For this criterion, "active" is defined as having received
             treatment within the past 5 years

          8. Have taken high-dose inhaled corticosteroids within 30 days prior to study
             vaccination. High-dose defined as per age as using inhaled high dose per reference

          9. The subject received immunoglobulin or another blood product within the 3 months prior
             to enrollment in this study

         10. The subject has received an inactivated vaccine within the 2 weeks or a live vaccine
             within the 4 weeks prior to enrollment in this study or plans to receive another
             vaccine within the next 28 days after vaccination

         11. The subject has an acute or chronic medical condition that, in the opinion of the
             investigator or appropriate sub-investigator, would render vaccination unsafe or would
             interfere with the evaluation of responses. These conditions include any acute or
             chronic medical disease or conditions defined as persisting for 3 months (defined as
             90 days) or longer, that would place the subject at an unacceptable risk of injury,
             render the subject unable to meet the requirements of the protocol, or may interfere
             with the evaluation of responses of the subject's successful completion of the study
