Abbreviations: GA: gestational age; w: week; d: days; VD: vaginal delivery; P-CS: planned cesarean section; Pt: Participant; SARS-CoV-2: Severe acute respiratory coronavirus-2; N/A: not available. Results of swabs analysed for SARS-CoV-2 are shown as “+” for a positive result and “-“ for a negative result. Test result (S/C) = (signal for test sample / signal at cutoff value) ≥ 1.00 is considered reactive (i.e. positive for antibodies) and result < 1.00 is considered non-reactive (i.e. negative for antibodies). * = Two vaginal swabs performed at the same time. **= If planned cesarean section, the vaginal swabs were performed immediately before and after CS. If vaginal delivery, two vaginal swabs were performed, one before an initial vaginal examination and one during the active phase of delivery or immediately after, respectively.
