Fig. 1

The duration of viral RNA shedding and the titers of specific IgG and IgM in the three groups. A The median duration of viral RNA shedding in the FV group was significantly lower than in the UV group (adjusted P < 0.001). The median duration of viral RNA shedding in the PV group lower than in the UV group, although the difference was not statistically significant (adjusted P = 0.23). B The median titers of SARS-CoV-2-specific IgG were significantly higher in the FV and PV groups than in the UV group (adjusted P < 0.001 and adjusted P = 0.008, respectively). C The median titers of SARS-CoV-2 specific-IgM were significantly higher in the FV and PV groups than in the UV group (adjusted P < 0.001 and adjusted P = 0.008, respectively). D Cumulative proportion of patients with detectable SARS-CoV-2 RNA by days after the illness onset between the UV, PV, and FV groups. Continuous variables were analyzed by variance analysis or Kruskal‒Wallis test. Kaplan‒Meier survival analysis was used to estimate the cumulative SARS-CoV-2 RNA negativity rate. A P value of less than 0.05 (two-tailed) was considered statistically significant. FV fully vaccinated, PV partially vaccinated, UV unvaccinated, SARS-CoV-2 Severe Acute Respiratory Syndrome Coronavirus 2, IQR interquartile range
