Brief Summary

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

The purpose of this study is to evaluate the safety and immunogenicity of one dose of H7N9 pandemic live attenuated influenza vaccine (H7N9 pLAIV) followed by AS03-adjuvanted H7N9 pandemic inactivated influenza vaccine (H7N9 pIIV).

Detailed Description

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

This study will evaluate the safety and immunogenicity of one dose of H7N9 pandemic live attenuated influenza vaccine (H7N9 pLAIV) followed by AS03-adjuvanted H7N9 pandemic inactivated influenza vaccine (H7N9 pIIV).

This study will enroll healthy adults who will choose which study group to join. Participants in Group 1 will receive one dose of H7N9 pLAIV in an inpatient setting at study entry (Day 0). They will remain in an isolation unit through at least Day 9. They will also receive one dose of AS03-adjuvanted H7N9 pIIV on Day 84.

Participants in Group 2 will receive one dose of AS03-adjuvanted H7N9 pIIV at study entry (Day 0) and a second dose of AS03-adjuvanted H7N9 pIIV at Day 84. Participants in Group 3 will receive one dose of AS03-adjuvanted H7N9 pIIV at study entry (Day 0).

All participants will attend multiple study visits through Day 264. Study visits may include blood collection, physical examinations, and nasal wash and nasal wick procedures.

These three groups will be compared to two historical control groups who received one dose of H7N9 pLAIV at study entry (Day 0), one dose of H7N9 pLAIV at Day 28, and one dose of unadjuvanted H7N9 pIIV at Day 84.

Eligibility Criteria

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

Inclusion Criteria

* Adult males and non-pregnant, non-breastfeeding females between 20 years and 49 years of age, inclusive. Children will not be recruited or enrolled in this study because they are not in the apparent risk group, for safety considerations, and because of the need for isolation.
* Are in good health, as determined by medical history and targeted physical examination to ensure any existing medical diagnoses or conditions (except those exclusionary) are stable. More information on this criterion can be found in the protocol.
* Agree to storage of blood specimens for future research.
* Available for the duration of the trial. Subjects must be willing and able to remain within the Isolation Unit for the specified duration of confinement.
