This EPSS will determine the vaccinee reporting rates (RRs) of suspected ADRs following routine vaccination with VaxigripTetra® and Efluelda® respectively, during the NH influenza season 2023/24. 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 2023/24. Study duration per participant 2 months (including 6 weeks for VC distribution 2 weeks for vaccinee reporting) following the first vaccination

| Measure | Description | Time Frame |
|---|---|---|
| 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 |
| Measure | Description | Time Frame |
|---|---|---|
| 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 | 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 |
