Primary

MeasureTime frame
Main Objective: To describe the incidence of pregnancy outcomes, pregnancy related adverse events of special interest (AESIs) and infant AESIs during the first pregnancy conceived within 2 years post-vaccination in participants enrolled in RSV MAT studies (by study arm, those previously received RSVPreF3 and control) up to Day 42 post-delivery.;Secondary Objective: • To describe the incidence of pregnancy outcomes, pregnancy related AESIs and infant AESIs during any pregnancy conceived within 2 years post-vaccination in participants enrolled in RSV MAT studies (by study arm, those previously received RSVPreF3 and control) up to Day 42 post-delivery. • To describe the incidence of selected pregnancy outcomes, pregnancy related AESIs and infant AESIs by risk status and by selected risk factors for or causes of those events/outcomes during pregnancies conceived within 2 years post-vaccination in participants enrolled in RSV MAT studies (by study arm, those previously received RSVPreF3 and control) up to day 42 post-delivery. ;Primary end point(s): 1.
