Yksityiskohtainen kuvaus
This was a Phase 2, open-label, single-arm, multicenter study designed to evaluate vaccine virus shedding and safety of trivalent influenza virus vaccine live, intranasal in children 6 to < 60 months of age.
Enrollment of approximately 200 participants was stratified by age, with 100 participants 6 to < 24 months of age (who reached their sixth month but not their second year birthday) and 100 participants 24 to < 60 months of age (who reached their second year but not their fifth year birthday).
Baseline medical history data collection included the participants prior receipt of influenza vaccine or history of laboratory-confirmed influenza illness in the previous influenza season.

Viruses were considered ca if they replicated at 25°C to a titer that was no more than two logs (100-fold) lower than the titer at 33°C.
After additional phenotypic and genotypic analyses, all evaluable samples retained the ca and ts phenotypes.

An SNMC is defined as a newly diagnosed medical condition that was of a chronic, ongoing nature and was assessed by the investigator as medically significant.
SNMCs included, but were not limited to, diabetes, asthma, autoimmune disease (lupus, rheumatoid arthritis), and neurological disease (epilepsy, autism).
