摘要:

目的 评估成人接种严重急性呼吸综合征冠状病毒2(SARS-CoV-2)疫苗后SARS-CoV-2 IgM、IgG和中和抗体的形成情况。方法 选取接受SARS-CoV-2疫苗接种的成人80名(疫苗接种组),检测疫苗接种完成后7 d内和第14天的血清SARS-CoV-2 IgM抗体、IgG抗体及中和抗体水平。以未接种SARS-CoV-2疫苗的健康成人80名作为对照组。按年龄和性别分别分组分析。结果 疫苗接种组接种结束后第14天,血清SARS-CoV-2 IgM抗体、IgG抗体及中和抗体阳性率分别为37.5%、98.8%和95.0%,IgM或IgG抗体的假阳性率为3.8%,中和抗体假阳性率为8.8%。男性SARS-CoV-2中和抗体阳性率高于女性(P<0.05)。疫苗接种组中,20~39岁受试者与40~60岁受试者之间3种抗体阳性率差异均无统计学意义(P>0.05)。接种第14天的血清SARS-CoV-2 IgG抗体水平显著高于接种7 d内(P=0.007),血清SARS-CoV-2 IgM抗体和中和抗体水平2个时间点之间差异均无统计学意义(P>0.05)。与接种第14天的血清SARS-CoV-2 IgG抗体、中和抗体阳性率比较,接种7 d内均较低(P<0.01),血清SARS-CoV-2 IgM抗体2个时间点之间差异无统计学意义(P>0.05)。结论 成年人完成SARS-CoV-2疫苗接种2周后,SARS-CoV-2 IgG抗体的阳性率可达95.0%,中和抗体阳性率可达86.2%。

Abstract:

Objective To evaluate the formation of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) IgM,IgG and neutralizing antibodies of the adult population who injected with the vaccine of SARS-CoV-2. Methods A total of 80 adults who received the vaccine of SARS-CoV-2(vaccination group) were enrolled,and the serum levels of SARS-CoV-2 IgM,IgG and neutralizing antibodies were determined within 7 d and 14 d after the completion of vaccination. Totally,80 healthy adults who did not receive the vaccine of SARS-CoV-2 were enrolled as control group. They were classified according to age and sex. Results On the 14th day after the completion of vaccination,the positive rate of SARS-CoV-2 IgM,IgG and neutralizing antibodies of vaccination group were 37.5%,98.8% and 95.0%,respectively. The false-positive rate of IgM or IgG antibody was 3.8%,and the false-positive rate of neutralizing antibody was 8.8%. The positive rate of SARS-CoV-2 neutralizing antibody in males was higher than that in females(P<0.05). There was no statistical significance in the positive rates of the 3 antibodies between those aged 20 to 39 and those aged 40 to 60 in vaccination group(P>0.05). The serum SARS-CoV-2 IgG antibody level on the 14th day of vaccination was higher than that within 7 d of vaccination(P=0.007). There was no statistical significance in serum SARS-CoV-2 IgM and neutralizing antibody levels at the 2 time points(P>0.05). The positive rates of serum SARS-CoV-2 IgG and neutralizing antibodies within 7 d of vaccination were lower than those on the 14th day(P<0.01). There was no statistical significance between the 2 time points of SARS-CoV-2 IgM antibody(P>0.05). Conclusions For 2 weeks after adults who completed the SARS-CoV-2 vaccination,the positive rate of SARS-CoV-2 IgG antibody reaches 95.0%,and that of neutralizing antibody reaches 86.2%.
