About
This open-label, single arm, multicenter study will enroll approximately 100 subjects. The study is designed to gather the safety and tolerability data in Japanese children 2 to 6 years of age that would support approval of MEDI3250 in Japan.
Full description
For children age 2 years through 6 years, the recommended dosage schedule for intranasal administration is 0.2 mL (0.1 mL per nostril). For children not previously vaccinated against seasonal influenza, a second dose should be given after an interval of at least 4 weeks.
For the safety and tolerability endpoint, data will be gathered on solicited symptoms, AEs and SAEs.
