Immunogenicity and Safety of AdimFlu-S, Formulation 2010-2011, in Infants Aged Between 6-12months Old

Adimmune Corporation59 enrolled

Overview

The purpose of this study is to evaluate the antibody response to each of the three influenza vaccine strains included in the seasonal flu vaccine(AdimFlu-S), as measured by hemagglutination inhibition (HAI) at 4 weeks after two doses of study vaccine, 4 weeks apart, in infants between 6 and 12 months of age.

Outcomes

Primary Outcomes

HA antibody titers will be determined using the WHO HAI reference technique.

Time frame: Serum samples will be obtained prior to vaccination (baseline), and 4 weeks after each vaccination.

Secondary Outcomes

The secondary objective is to evaluate the safety and tolerability profiles including the presence or absence of the pre-specified reactogenicity events and other serious/non-serious adverse events of the AdimFlu-S manufactured by Adimmune Corporation.

Safety data will consist of reactogenicity, serious and non-serious adverse events. Reactogenicity events are pre-specified adverse events systematically recorded for 7 days after each vaccination. The events included fever (≥38.0°C), runny nose or nasal congestion, cough, sore throat, muscle aches, headache, vomiting, nausea and malaise. Furthermore, the local (injection site) reactions were also evaluated, including soreness/pain, swelling, redness, ecchymosis and limitation of arm motion.

Time frame: (4 weeks after two doses of study vaccine, 4 weeks apart), Physical examination will be performed at each visit. Reactogenicity will be recorded for 7 days after each vaccination.
