About this trial
This is an interventional prevention trial for Influenza focused on measuring influenza, inactivated influenza A/H7N7 vaccine, parent protocol
Eligibility Criteria
Inclusion Criteria:
- Male or non-pregnant female (as indicated by a negative urine pregnancy test immediately prior to vaccine administration) between the ages of 18 and 40 years, inclusive.

(*A stable medical condition is defined as no recent change in prescription medication, 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. Any change that is due to change of health care provider, insurance company, etc, or is done for financial reasons, as long as in the same class of medication, will not be considered a violation of the inclusion criterion. Any change to prescription medication due to improvement of a disease outcome will not be considered a violation of the inclusion criterion.)

- Have an active neoplastic disease or a history of any hematologic malignancy.
- Have long-term use of oral steroids, parenteral steroids, or high-dose inhaled steroids (>800 micrograms/day of beclomethasone dipropionate or equivalent) within the preceding 6 months (nasal and topical steroids are allowed.)
- Have a history of receiving immunoglobulin or other blood product within the 3 months prior to enrollment in this study.
- Have received any other licensed vaccines within 2 weeks (for inactivated vaccines) or 4 weeks (for live vaccines) prior to vaccination in this study.
- Have 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).
- Have a history of severe reactions following immunization with contemporary influenza virus vaccines.
- Have an acute illness, including an oral temperature greater than 100.4 degrees Fahrenheit, within 1 week of vaccination.

- Plan to enroll in another clinical trial at any time during the study period.
- Have any condition that would, in the opinion of the site investigator, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol.
