Emergence of severe acute respiratory syndrome (SARS) from the winter of 2002 to the spring of 2003 has caused a serious threat to public health.
To evaluate the safety and immunogenicity of the inactivated SARS coronavirus (SARS-CoV) vaccine, 36 subjects received two doses of 16 SARS-CoV units (SU) or 32 SU inactivated SARS-CoV vaccine, or placebo control.
On day 42, the seroconversion reached 100% for both vaccine groups. On day 56, 100% of participants in the group receiving 16 SU and 91.1% in the group receiving 32 SU had seroconverted. The geometric mean titre of neutralizing antibody peaked 2 weeks after the second vaccination, but decreased 4 weeks later.
The inactivated vaccine was safe and well tolerated and can elicit SARS-CoV-specific neutralizing antibodies.
2002年冬到2003年春严重急性呼吸综合征（SARS）的出现对公众健康造成了严重威胁。
为评估灭活SARS冠状病毒（SARS-CoV）疫苗的安全性和免疫原性，36名受试者接种了两剂16个SARS-CoV单位（SU）或32个SU的灭活SARS-CoV疫苗，或接受安慰剂对照。
在第42天，两个疫苗组的血清转化率均达到100%。在第56天，接受16个SU组的100%参与者和接受32个SU组的91.1%参与者发生了血清转化。中和抗体的几何平均滴度在第二次接种后2周达到峰值，但在4周后下降。
该灭活疫苗安全且耐受性良好，可引发SARS-CoV特异性中和抗体。
