Resum:	Background: Seasonal influenza is prevented through annual vaccination, especially in children and older adults. These vaccines are annually updated based on World Health Organization recommendations and require continuous safety monitoring. Objective: We assessed the frequency and severity of adverse events within 7 days of administering GSK's inactivated quadrivalent seasonal influenza vaccine (IIV4) in Belgium, Germany, and Spain during the 2022/2023 influenza season. Methods: In this enhanced safety surveillance study, adults who received GSK's IIV4 and parents/guardians/legally acceptable representatives of vaccinated children (aged 6 months-17 years) were invited to complete adverse drug reaction cards reporting adverse events within 7 days post-vaccination. Results: In total, 1332 participants (53. 6% female) received at least one dose of GSK's IIV4, including 43 children who received two doses. Overall, 97. 8% of adverse drug reaction cards were completed and returned in the study. All participants in Belgium were adults, while 54. 7% and 7. 4% in Spain and Germany, respectively, were pediatric participants aged 6 months-17 years. After Dose 1, across all age groups, 49. 8% of participants reported at least one adverse event. The most common adverse events (cumulative frequency.
