Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study we are trying to understand whether previous infection with a particular virus, namely cytomegalovirus (CMV), influences the ability of the immune system to respond to new infections or vaccinations with age.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators want to compare the T- and B-cell response to conventional intramuscular trivalent influenza vaccine (TIV) in elderly individuals dependent on the presence and duration of CMV infection by analyses of vaccine-induced plasmablasts, antibodies and antigen-specific T cells. Healthy volunteers, \> 60 years of age, will be identified by the Stanford Blood Center based on their history of positive or negative CMV serologies. Baseline blood samples will be drawn from all study participants prior to immunization. All participants will receive a single dose of 2012-2013 licensed TIV. Volunteers will complete 3 study visits at Day 0, Day 7 and Day 28.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Otherwise healthy, ambulatory adult 60 years of age or above.
* Self-identified by a participant after notification by Stanford Blood Center (SBC) of their group assignment based review of SBC CMV data:

* CMV-negative: Donor has donated at least twice during the last 3 years AND donor's most recent two donations tested CMV antibody negative.
* CMV positive longstanding infection: Donor has donated at least once within the "recent" timeframe (past three years) AND donor's most recent donation tested CMV antibody positive AND donor had at least one donation prior to 2000 that tested CMV antibody positive.
* Recent CMV converters: Donor has donated at least once within the "recent" timeframe (past three years) AND donor's most recent two donations tested CMV antibody positive AND donor had at least two CMV negative donations in the past.
* Willing to complete the informed consent process.
* Availability for follow-up for the planned duration of the study at least 28 days after immunization.

Exclusion Criteria

* Prior off-study vaccination with the current 2012-2013 seasonal influenza vaccine
* Allergy to egg or egg products, or to vaccine components or thimerosal (TIV multidose vials only)
* Life-threatening reactions to previous influenza vaccinations.
* Active systemic or serious concurrent illness, including febrile illness on the day of vaccination
* Weight less than 110 lbs
* History of immunodeficiency (including HIV infection)
* Known or suspected impairment of immunologic function, including, but not limited to, clinically significant liver disease, diabetes mellitus treated with insulin, moderate to severe renal disease, or any other chronic disorder which, in the opinion of the investigator, might jeopardize volunteer safety or compliance with the protocol.
* Blood pressure \>150 systolic or \>95 diastolic at first study visit
* Hospitalization in the past year for congestive heart failure or emphysema.
* History of chronic Hepatitis B or C.
* Recent or current use of immunosuppressive medication, including systemic glucocorticoids (corticosteroid nasal sprays and topical steroids are permissible in all groups)
* Malignancy, other than squamous cell or basal cell skin cancer (includes solid tumors such as breast cancer or prostate cancer with recurrence in the past year, and any hematologic cancer such as leukemia).
* Autoimmune disease (including rheumatoid arthritis treated with immunosuppressive medication such as Plaquenil, methotrexate, prednisone, Enbrel) which, in the opinion of the investigator, might jeopardize volunteer safety or compliance with the protocol.
* History of blood dyscrasias, renal disease, or hemoglobinopathies requiring regular medical follow up or hospitalization during the preceding year
* Use of any anti-coagulation medication such as Coumadin or Lovenox, or anti-platelet agents such as aspirin (except up to 325 mg aspirin per day), Plavix, or Aggrenox must be reviewed by investigator to determine if this would affect the volunteer's safety.
* Receipt of blood or blood products within the past 6 months or planned receipt of blood products prior to completion of study visits.
* Medical or psychiatric condition or occupational responsibilities that preclude participant compliance with the protocol
* Inactivated vaccine 14 days prior to vaccination or planned non-study vaccination prior to completion of Visit 03 (\~Day 28 after the study vaccination)
* Live, attenuated vaccine within 60 days of vaccination or planned non-study vaccination prior to completion of Visit 03 (\~Day 28 after the study vaccination)
* Need an allergy immunization (that cannot be postponed) during the study period V01 to V03 (\~Day 28)
* History of Guillain-Barré Syndrome
* Use of investigational agents within 30 days prior to enrollment or planned use of investigational agents prior to completion of study visits
* Donation of the equivalent of a unit of whole blood within 6 weeks or a unit of platelets within 2 weeks prior to enrollment or planned blood donation prior to completion of study visits.
* Any condition which, in the opinion of the investigator, might interfere with volunteer safety, study objectives or the ability of the participant to understand or comply with the study protocol.
