Clinical Trial 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

Description:

Study duration per participant 2 months (including 6 weeks for VC distribution + 2 weeks for vaccinee reporting) following the first vaccination

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Vaccinee reporting rate of suspected adverse drug reactions (ADRs) following routine vaccination with VaxigripTetra® and Efluelda®	Number of vaccinees who reported at least 1 suspected ADR divided by the total number of vaccination cards (VCs) distributed	Within 7 days after vaccination
Secondary	Vaccinees' reporting rate of ADRs according to age group		Within 7 days after vaccination
Secondary	Vaccinees' reporting rate of serious suspected ADRs at any time following vaccination within the EPSS period	Serious suspected ADRs will be collected from vaccination up to the end of data collection. Data collection ends when 1000 vaccination cards have been distributed (per vaccine brand) plus 2 weeks or 2 months following the first vaccination, whichever comes first.	From vaccination to end of data collection (maximum 2 months following first vaccination)
Secondary	Vaccinees' reporting rate of suspected ADR at any time following vaccination within the EPSS period	Suspected ADRs will be collected from vaccination up to the end of data collection. Data collection ends when 1000 vaccination cards have been distributed (per vaccine brand) plus 2 weeks or 2 months following the first vaccination, whichever comes first	From vaccination to end of data collection (maximum 2 months following first vaccination
