Enhanced Safety Surveillance of GlaxoSmithKline's (GSK's) Quadrivalent Seasonal Influenza Vaccines During the 2018/19 Influenza Season

Enhanced Safety Surveillance of GSK's Quadrivalent Seasonal Influenza Vaccines

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.

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.

Inclusion Criteria:

• Subjects who, in the opinion of the investigator, can and will comply with the requirements of the protocol (e.g., complete the ADR card, return for the next scheduled visit or return the ADR card by mail within a timely manner).
• A male or female subject vaccinated with GSK's quadrivalent seasonal influenza vaccine (one or two dose schedule) according to the routine medical practices between 01 October 2018 and 31 December 2018.
• Subjects aged 6 months or above at the time of the vaccination according to the countries' specificities.
• Written informed consent/informed assent obtained from the subjects/subjects' parent(s)/Legally Acceptable Representative(s) (LARs).

Exclusion Criteria:

• Child in care.
