一项小型的初步实验室研究表明,俄罗斯SputnikV疫苗接种者的Ommicron中和抗体水平下降的幅度小于辉瑞疫苗。
这项由俄罗斯和意大利联合进行的研究由负责向国外推销疫苗的俄罗斯直接投资基金(Russian Direct Investment Fund)资助,该研究比较了接受了不同疫苗者的血清。
这项初步研究是由意大利Spallanzani 研究所和莫斯科Gamaleya 研究所的科学家进行的,后者是Sputnik V疫苗的开发者。
研究人员说,第二剂疫苗接种后3到6个月的样本显示,两剂Sputnik V疫苗接种者体内针对Omicron的抗体水平要高于那些接种了辉瑞公司疫苗的人。
在研究中,51人接种了Sputnik V疫苗,17人接种了两针辉瑞疫苗。
这项将寻求同行评阅的研究显示,74.2%接种了Sputnik疫苗的人的血清中检测到了ommicron特异性中和抗体,而在接种了辉瑞/BioNtech疫苗的人中,这一比例为56.9%。
Sputnik V疫苗的开发者Gamaleya研究所早些时候进行的一项初步研究表明,与单独使用两剂Sputnik V疫苗相比,Sputnik Light 疫苗加强针产生了更强的Omicron特异性的抗体反应。
