Figure 3. Variance in neutralizing activity in maternal and cord plasma from vaccination cohort and infection cohort.

Paired maternal and cord blood NT₅₀ titers against each SARS-CoV-2 strain of each vaccinated patient and each infected patient were matched and displayed as a single row, ordered by increasing gestational age (GA), grouped by trimester. Variability of NT₅₀ was compared using the Brown-Forsythe test. Patient characteristics are indicated by color (trimester of exposure: red, first trimester; blue, second trimester; yellow, third trimester. Vaccine type is indicated by color (green, mRNA-1273; orange, BNT162b2). Fetal sex is indicated by pink for female fetus; blue for male fetus). N/A, samples were not sufficient.
