Quantification of SARS-CoV-2 specific antibodies induced by inactivated COVID-19 vaccines. The level of anti-SARS-CoV-2 IgM (A), IgG (C) and surrogate neutralizing antibodies (E) in 93 enrolled healthy participants from T1 to T4. The level of anti-SARS-CoV-2 IgG (G) and surrogate neutralizing antibodies (I) in 93 enrolled healthy participants from T5 to T7. The total levels of anti-SARS-CoV-2 IgM (B), IgG (D) and surrogate neutralizing antibodies (F) after primary immunization. The total levels of anti-SARS-CoV-2 IgG (H) and surrogate neutralizing antibodies (J) after booster immunization. Statistical significance was determined by Kruskal–Wallis test. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001
