Safety Surveillance of VaxigripTetra® and Efluelda® Influenza Vaccines in Europe During the Influenza Season 2022/23
Enhanced Passive Safety Surveillance of VaxigripTetra® (Quadrivalent Inactivated Split Virion Influenza Vaccine, Intramuscular Route) and Efluelda® (High-dose Quadrivalent Inactivated Split Virion Influenza Vaccine, Intramuscular Route) Vaccines in Europe During the Influenza Season 2022/23.

Brief Summary
This is an enhanced passive safety surveillance conducted in routine clinical care setting. Spontaneously reported ADRs will be collected by study staff following routine vaccination. The primary objective of this surveillance is to estimate the vaccinee reporting rate (RR) of suspected adverse drug reactions (ADRs) occurring within 7 days following routine vaccination with VaxigripTetra® and Efluelda®, respectively, during the Northern Hemisphere (NH) influenza season 2022/23. The secondary objectives of the study are:
- To estimate the vaccinee reporting rate of suspected ADRs occurring within 7 days following routine vaccination with VaxigripTetra® and Efluelda®, respectively, according to the pre-defined age groups (not applicable for Efluelda®)
- To estimate the vaccinee reporting rate of serious suspected ADRs after vaccination with VaxigripTetra® and Efluelda®, respectively, at any time following vaccination, within the EPSS

Outcome Measures
Primary Outcomes (1)
Vaccinee reporting rate of suspected adverse drug reactions (ADRs) following routine vaccination with VaxigripTetra® and Efluelda®

Within 7 days after vaccination
Secondary Outcomes (3)
Vaccinees' reporting rate of ADRs according to age group
Within 7 days after vaccination
Vaccinees' reporting rate of serious suspected ADRs at any time following vaccination within the EPSS period
From vaccination to end of data collection (maximum 2 months following first vaccination)
Vaccinees' reporting rate of suspected ADR at any time following vaccination within the EPSS period
From vaccination to end of data collection (maximum 2 months following first vaccination
