Figure 1. Patient selection flow chart.

Patients were recruited from 8 medical centers in Israel and were all SARS-CoV-2 RT-PCR negative at delivery. The original study groups included all the paired samples from the vaccinated (n = 92) and SARS-CoV-2 (n = 74) groups together with the original matched control group (n = 66). Samples were thereafter excluded for technical testing problems, leading to a total of n = 62, n = 65, and n = 86 analyzed samples for the control, SARS-CoV-2, and vaccinated groups, respectively. Seropositivity for nucleocapsid (N) was set at the level of the top 90% of the PCR-positive recovered group and verified by positivity for S1, S2, and RBD (see Supplemental Figures 1 and 2). The same threshold was used to reveal seropositive cases in the vaccinated and the control groups.
