About seasonal influenza in children
Seasonal influenza (the "flu") is a contagious respiratory illness, caused by flu viruses.1 There are two main types of flu viruses, A and B, that spread between people and can cause mild to severe illness.2 Most flu activity in the US occurs from October-May, and it usually peaks in January and February.3
According to the US Centers for Disease Control and Prevention (CDC), the flu is more dangerous than the common cold for children. Severe flu complications are most common in children under the age of 2 years. Each year, many children get sick with seasonal influenza and some of those illnesses result in death. On average, 20,000 children under the age of 5 are hospitalized because of influenza complications.4 The CDC recommends that everyone aged 6 months and older get a seasonal flu vaccine.5
About FLUARIX® QUADRIVALENT
FLUARIX® QUADRIVALENT was first approved in 2012 in the U.S. for the prevention of influenza disease in people three years of age and older. It is also approved in more than 30 other countries worldwide.
Important Safety Information for FLUARIX® QUADRIVALENT

If Guillain-Barré syndrome has occurred within six weeks of receipt of a prior influenza vaccine, the decision to give FLUARIX® QUADRIVALENT should be based on careful consideration of the potential benefits and risks.
Syncope (fainting) can occur in association with administration of injectable vaccines, including FLUARIX® QUADRIVALENT. Procedures should be in place to avoid falling injury and to restore cerebral perfusion following syncope.
