NCT00240903

Brief Summary

The purpose of this study is to determine whether having received an H5 vaccine in the past primes the immune system to respond rapidly to another dose of H5 vaccine. One hundred seventeen participants in a previous vaccine study (involving the A/Hong/Kong/97 virus) during the fall of 1998 at the University of Rochester will be eligible to enroll in this study. Participation in this study will up to 64 days and will involve donation of small samples of blood 7, 28, and 56 days after vaccination.

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participant in the previous study of the rec H5 HA 1997 vaccine.
  • Male or non-pregnant female (as indicated by a negative urine pregnancy test immediately prior to vaccine administration) between the ages of 18 and 65 years.
  • Females of childbearing potential who are at risk of becoming pregnant must agree to practice adequate contraception (i.e., barrier method, abstinence, Depo-Provera, Norplant, oral contraceptives, contraceptive patches or other licensed, effective methods) for the entire study period.
  • In good health, as determined by medical history and a targeted physical examination, if necessary.
  • Able to understand and comply with planned study procedures.
  • Able to provide informed consent and be available for all study visits.

You may not qualify if:

  • Has participated in DMID 04-063 Study.
  • Has a known allergy to eggs, other components of the vaccine or latex.
  • Has a positive urine pregnancy test at screening or prior to vaccination (if female), is lactating, or has the intention to become pregnant within 3 months of enrollment in this study.
  • Is undergoing immunosuppression as a result of an underlying illness or treatment.
  • Has an active neoplastic disease or a history of any hematologic malignancy.
  • Is using oral or parenteral steroids, high-dose inhaled steroids (\>800 mcg/day of beclomethasone dipropionate or equivalent) or other immunosuppressive or cytotoxic drugs.
  • Has a history of receiving immunoglobulin or other blood products within the 3 months prior to enrollment in this study.
  • Has received any other licensed vaccines within 2 weeks (for inactivated vaccines) or 4 weeks (for live vaccines) prior to enrollment in this study.
  • Has an acute or chronic medical condition that, in the opinion of the investigator, would render vaccination unsafe or would interfere with the evaluation of responses (this includes, but is not limited to: known chronic liver disease, significant renal disease, unstable or progressive neurological disorders, diabetes mellitus, and transplant recipients).
  • Has a history of severe reactions following immunization with contemporary influenza virus vaccines.
  • Has an acute illness, including an oral temperature greater than 100.0 degrees F within one week of vaccination.
  • Received an experimental vaccine or medication within 1 month prior to enrollment in this study, or expects to receive an experimental vaccine, medication, or blood product during the 6 to 7-month study period.
  • Has a history of alcohol abuse or drug abuse (including chronic pain medication) in the last 5 years.
  • Has any condition that would, in the opinion of the site principal investigator, place the volunteer at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol.
