 How to Read a Study Record
The purpose of this study is to comply with the European Medicines Agency (EMA) guidance on enhanced safety surveillance for seasonal influenza vaccines in the European Union (EU) and aims to assess adverse events of interest (AEIs) experienced within 7 days post vaccination with GSK's quadrivalent seasonal influenza vaccine (AlphaRix Tetra in Belgium; Influsplit Tetra in Germany, Fluarix Tetra in Spain).
This study may help to inform decisions regarding future influenza vaccine safety surveillance for influenza vaccines in Europe.
Condition or disease  Intervention/treatment  Phase 

Influenza, Human  Other: Passive enhanced safety surveillance  Phase 4 
The key objective of the EMA enhanced safety surveillance is to rapidly detect a significant increase in the frequency and/or severity of expected reactions (local, systemic or allergic reactions) that may indicate a potential risk.
The study is a passive enhanced safety surveillance aiming to collect prospectively AEIs and/or other AEs experienced within 7 days post vaccination with GSK's quadrivalent seasonal influenza vaccine, using customized Adverse Drug Reaction cards. Data will be collected via the healthcare provide (HCP) or study medical staff who administer the seasonal influenza vaccination or who provide the inform consent form and the ADR cards.
