Key exclusion criteria
- Acute (severe) febrile illness. Enrollment could be considered if the fever is absent
for 72 hours.

- History of any anaphylaxis, serious vaccine reactions or hypersensitivity, including
allergic reactions, to any component of vaccine or medical equipment whose use is
foreseen in this study.

- Clinical conditions representing a contraindication to intramuscular vaccination and
blood draws. These may include known bleeding disorders, or treatment with
anticoagulants in the 3 weeks preceding vaccination.

Summary
Brief summary
This phase 3 clinical study is a randomized, observer-blind, multicenter study of QIVc versus
a non-influenza vaccine in subjects 6 months though 47 months of age. The purpose of this
study is to evaluate efficacy of QIVc in the prevention of Reverse transcription polymerase
chain reaction (RT-PCR) confirmed influenza A or B disease in children 6 through 47 months of
age, compared to a non-influenza vaccine.
