结局指标
主要结局
Number of Participants With All Cause Hospitalization Visits: 18-64 Years Old
时间窗: From Day 15 of vaccination till end of follow-up observation period, from 14-Sep-2022 through 14 February 2023 (approximately 5 months); data was extracted and observed in this retrospective study from 05-May-2023 to 12-May-2023 (8 days)
Hospitalization due to any cause is defined as an overnight stay, or longer, in a hospital environment (emergency room, observation unit or in-patient care, or similar facility including admission to a day care facility). To account for imbalance in participant characteristics between the vaccine exposure groups, 2 separate logistic regression models were used. The two models were: Model 1: Same day vs COVID-19 alone, and Model 2: Same day vs Flu (SIV) alone.
Number of Participants With All Cause Hospitalization Visits: >=65 Years Old
时间窗: From Day 15 of vaccination till end of follow-up observation period, from 14-Sep-2022 through 14 February 2023 (approximately 5 months); data was extracted and observed in this retrospective study from 05-May-2023 to 12-May-2023 (8 days)

To account for imbalance in participant characteristics between the vaccine exposure groups, 2 separate logistic regression models were used. The two models were: Model 1: Same day vs COVID-19 alone, and Model 2: Same day vs SIV alone.
Number of Participants With Composite Coronavirus Disease (COVID-19)-Related Hospitalization, Emergency Department or Urgent Care Visits: Same Day Versus COVID-19 Alone
时间窗: From Day 15 of vaccination till end of follow-up observation period, from 14-Sep-2022 through 14 February 2023 (approximately 5 months); data was extracted and observed in this retrospective study from 05-May-2023 to 12-May-2023 (8 days)
Hospitalization, emergency department or urgent care visits with COVID-19 diagnosis code (International Classification of Diseases, 10th revision \[ICD-10-CM\]: U07.1) in any position. To account for imbalance in participant characteristics between the vaccine exposure groups, 2 separate logistic regression models were used. The two models were: Model 1: Same day vs COVID-19 alone, and Model 2: Same day vs SIV alone. In this outcome measure data is reported for Model 1: Same day vs COVID-19 alone.
Number of Participants With Composite Influenza Related Hospitalization, Emergency Department or Urgent Care Visits: Same Day Versus SIV Alone
时间窗: From Day 15 of vaccination till end of follow-up observation period, from 14-Sep-2022 through 14 February 2023 (approximately 5 months); data was extracted and observed in this retrospective study from 05-May-2023 to 12-May-2023 (8 days)
Hospitalization, emergency department or urgent care visits with Influenza diagnosis code (ICD-10-CM: J09.X, J10.X, J11.X) in any position. To account for imbalance in participant characteristics between the vaccine exposure groups, 2 separate logistic regression models were used. The two models were: Model 1: Same day vs COVID-19 alone, and Model 2: Same day vs SIV alone. In this outcome measure data is reported for Model 2: Same day vs SIV alone.
Number of Participants With COVID-19 Related Outpatient Visits: Same Day Versus COVID-19 Alone
时间窗: From Day 15 of vaccination till end of follow-up observation period, (from 14-Sep-2022 through 14 February 2023 (approximately 5 months); data was extracted and observed in this retrospective study from 05-May-2023 to 12-May-2023 (8 days)
COVID-19 diagnosis code (ICD-10-CM: U07.1) in any position. An outpatient visit refers to any encounter that is in the outpatient setting. To account for imbalance in participant characteristics between the vaccine exposure groups, 2 separate logistic regression models were used. The two models were: Model 1: Same day vs COVID-19 alone, and Model 2: Same day vs SIV alone. In this outcome measure data is reported for Model 1: Same day vs COVID-19 alone.
