NCT05568979

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®

    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 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
