The coronavirus are a wide group of viruses among that the SARS-CoV-2 is included (family Coronaviridae, subfamily Coronavirinae, genus Betacoronavirus and subgenus Sarbecovirus). Its main structural proteins are the membrane (M), the envelope (E), the nucleocapsid (N) and spike (S). The immune response to SARS-CoV-2 involves the cellular and the humoral sides, with neutralizing antibodies fundamentally directed against the S antigen. Although the seroprevalence data are frequently assumed as protection markers, no necessarily they are. In Spain, it is estimated that, to assure the herd immunity, at least four-fifths of the population should be immunoprotected. Due the high fatality rate of COVID-19, the acquisition of the protection only by the natural infection it not assumable and other measures as the mass immunization are required. Currently, there are several vaccine prototypes (including life virus, viral vectors, peptides and proteins and nucleic acid) in different phase of clinical evaluation. Foreseeably, some of these news vaccines would be soon commercially available. In this text, aspects related to these issues are reviewed.
冠状病毒是一大类病毒,其中包括严重急性呼吸综合征冠状病毒2(SARS-CoV-2)(冠状病毒科、冠状病毒亚科、β冠状病毒属、Sarbecovirus亚属)。其主要结构蛋白包括膜蛋白(M)、包膜蛋白(E)、核衣壳蛋白(N)和刺突蛋白(S)。对SARS-CoV-2的免疫反应涉及细胞免疫和体液免疫两个方面,中和抗体主要针对S抗原。虽然血清流行率数据常被视为保护指标,但不一定如此。在西班牙,据估计,为确保群体免疫,至少五分之四的人口应获得免疫保护。由于COVID-19的高死亡率,仅通过自然感染获得保护是不可行的,还需要采取大规模免疫等其他措施。目前,有几种疫苗原型(包括活病毒、病毒载体、肽和蛋白质以及核酸)正处于不同阶段的临床评估中。可以预见,其中一些新型疫苗很快将上市。本文将对与这些问题相关的方面进行综述。
