- Presence of household member or close contact who has known immunodeficiency, is receiving immunosuppressant medication, is undergoing or soon to undergo cancer chemotherapy, has been diagnosed with emphysema, COPD, or other severe lung disease, has received a bone marrow or solid organ transplant, resides in a nursing home
- Evidence of vaccinations within the four weeks prior to inoculation/dosing, whichever occurs first.
- Intention to receive any vaccination(s) before the Day 28 Follow Up Visit
- Prior participation in another Human Viral Challenge Study in the preceding 12 months taken from the date of inoculation in the previous study to the date of expected inoculation in this study.
- Receipt of systemic glucocorticoids or systemic antiviral drugs within six months prior to inoculation/dosing.
- Receipt of any systemic chemotherapy agent, immunoglobulins or any other cytotoxic or immunosuppressive drugs at any time.
