Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Healthy Japanese Children Age 2 Years Through 6 Years Drug: MEDI3250 Phase 3

Detailed 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.

Primary Outcome Measures :
  1. Number of Participants With Solicited Symptoms Experienced From Administration of MEDI3250 [ Time Frame: 14 days post vaccination ]

    Solicited symptoms experienced from administration of investigational product through 14 days post vaccination by dose number.

    Solicited symptoms are events that are considered likely to occur post dosing. For this study, solicited symptoms include "Fever ≥ 100.4°F (38.0°C) by any route", "Runny/stuffy nose", "Sore throat", "Cough", "Headache", "Generalized muscle aches", "Decreased activity level (lethargy) or tiredness/weakness", "Decreased appetite" and "Collection of specific solicited symptoms (sore throat, headache, generalized muscle aches) will be omitted when, according to the judgment of the investigator, the subject is too young to reliably report a particular symptom"
