NCT00169234

Brief Summary

The purpose of this study is to give seniors different doses of a new pneumococcal vaccine called PCV7 to evaluate the safety of the vaccine and compare the immune response to find out which amount gives the best immune response. The PCV7 vaccine is currently licensed by the FDA for use in infants and toddlers only.

Eligibility Criteria

Age70 Years - 79 Years
Sexall
Healthy VolunteersNo
Age GroupsOlder Adult (65+)

You may qualify if:

  • Age 70 through 79 years (up to the day prior to the 80th birthday)
  • Previously received exactly one dose of PPV23, and that dose was received on or after their 65th birthday and at least 5 years before the date of study enrollment
  • Expected to reside in the area for at least 13 months
  • Able to understand and give informed consent
  • Able to perform study procedures
  • Able to be contacted by telephone for follow-up on adverse events

You may not qualify if:

  • Received \>=2 doses of PPV23 prior to study enrollment.
  • Living non-independently in an institutional setting, such as a nursing home. Persons living independently in adult residence communities will be eligible.
  • Use of any investigational vaccine within the past 30 days or planned use during the study period.
  • Current or planned participation in a research study of an investigational drug. Participation in research studies that involve use of licensed drugs, for either approved or investigational indications, will be permitted with the approval of the site PI, as will participation in research studies that do not involve medications.
  • Current use or previous chronic administration, defined as \>=14 days during the previous six months, of immunosuppressants or other immune-modifying drugs. (For oral or injected corticosteroids, the immune-modifying dose is defined as prednisone or its equivalent \>=10 mg/day). Topical steroids are allowed.
  • Current use of high doses of inhaled steroids, defined as per Table 3.
  • Use of cytotoxic therapy in the previous 5 years.
  • Plans to receive cytotoxic therapy during the study period.
  • Receipt of parenteral immunoglobulin or blood products within three months of study.
  • Plans to receive parenteral immunoglobulin or blood products within the study period.
  • Current ongoing use of warfarin or heparin or has a bleeding disorder, such as ITP.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection.
  • Anatomic or known functional asplenia.
  • History of a hematologic malignancy or a pre-malignant condition (i.e., leukemia, lymphoma, multiple myeloma, myelodysplasia).
  • Active neoplastic disease, excluding local skin cancer or other malignancies (e.g. prostate cancer) that are stable in the absence of immunosuppressive/cytotoxic or radiation therapy.
  • +4 more criteria
