Figure 1. Maternal humoral immune response following infection
with SARS-CoV-2 according to time from infection to delivery
(A) The rate of pregnant women with positive serum anti-spike
IgG (IgG-S), anti-spike IgM (IgM-S) and anti-nucleocapsid IgG (IgG-N)
antibodies over time (weeks) from infection.
(B) LOESS smooth curve (smoothing parameter 0.4) of mean
antibody levels according to time between COVID-19 disease and delivery
(weeks). Antibodies levels were normalized by dividing each value with
the highest value measured. Anti-spike antibodies were also multiplied
by 3 in order to fit the scale. Antibody levels below the seropositivity
threshold are shown as zero. Note that the graph represents the rate of
antibody level decline and not their actual values.
