- Participants of reproductive potential must agree to use acceptable contraceptive measures as per the protocol as a minimum, and local guidelines, if more stringent
Exclusion
- Pregnant or lactating women, or women who intend to become pregnant during the study
- Hypersensitivity to monoclonal antibodies or any constituents (sodium succinate, sucrose, polysorbate 20) of study drug
- Hypersensitivity to the active substance or to any excipients of oseltamivir
- Investigational therapy within the 30 days prior to study treatment

- Participants requiring home or baseline oxygenation therapy
- Participants with history of chronic lung disease with a documented SpO2 less than (\<) 95% off oxygen
- Participants on chronic dose of corticosteroids exceeding 10 milligrams per day (mg/day) of prednisone or equivalent steroid dose for duration of greater than 14 days within 30 days of entry into study
- Participants with the following significant immune suppression: bone marrow or solid organ transplant in the previous 12 months; cancer chemotherapy in the previous 12 months, HIV infection with most recent Cluster of Differentiation 4 (CD4) \<200 cells per milliliter (cells/mL), or other significant immune suppression as determined by the investigator in discussion with the Sponsor Medical Monitor
