Figures & data

Table 1. Demographic characteristics of the participants.

Figure 1. Positive rates of antibodies at different inoculation durations in pregnant women who received two doses of inactivated COVID-19 vaccine.

Inoculation Duration was defined as the time interval between the last dose of vaccine and blood collection. NAb: neutralizing antibody.

Figure 2. RCS models for antibodies in pregnant women who received two doses of inactivated COVID-19 vaccine. a: RCS model for NAb of pregnant women who received two doses of inactivated vaccine. b: RCS model for IgG antibody of pregnant women who received two doses of inactivated vaccine. c: RCS model for NAb of pregnant women who received two doses of inactivated vaccine during pregnancy. d: RCS model for IgG antibody of pregnant women who received two doses of inactivated vaccine during pregnancy. The x-axis is the duration of inoculation. The y-axis is the predicted or values of antibody positivity. The shaded area represents the 95% confidence interval. These models were adjusted for age.
