The only effective way to provide individuals with herd immunity against the novel coronavirus [SARS-CoV-2] is to administer an effective vaccine that will help check the current pandemic status. In India, the central drugs standard control organization (CDSCO) has granted the emergency-use authorization [EUA] to three vaccines namely, Covishield (live vaccine, Oxford AstraZeneca, United Kingdom being manufactured by the Serum Institute of India), Covaxin (inactivated vaccine, Bharat Biotech, India) and Sputnik V (live vaccine, Gamaleya, Russia). However, there is a rising need for the efficacy of the vaccines to be proven against the "SARS-CoV-2 viral variants." Also, human plasma is polyclonal in nature with an inherent propensity to identify multiple epitopes of either an antigen or pathogen. With this context in mind, the researchers hypothesize that using COVID-19 convalescent plasma [CCP] harvested from the locally recovered individuals [i.e. potential CCP donors] may be particularly beneficial in combating not only the founder SARS-CoV-2 virus but also the geographically determined SARS-CoV-2 variants among the regionally affected COVID-19 patients.
为个体提供针对新型冠状病毒[SARS-CoV-2]的群体免疫力的唯一有效方法是接种有效的疫苗,以帮助控制当前的大流行状况。在印度,中央药物标准控制组织(CDSCO)已授权三种疫苗紧急使用,即 Covishield(活疫苗,由印度血清研究所生产的牛津阿斯利康,英国制造)、Covaxin(灭活疫苗,印度 Bharat Biotech)和 Sputnik V(活疫苗,俄罗斯 Gamaleya)。然而,越来越需要证明疫苗对“SARS-CoV-2 病毒变体”的有效性。此外,人类血浆本质上是多克隆的,具有识别抗原或病原体的多个表位的固有倾向。有鉴于此,研究人员假设,使用从当地康复者(即潜在的 CCP 供体)采集的 COVID-19 恢复期血浆[CCP],可能不仅对对抗最初的 SARS-CoV-2 病毒,而且对该地区受 COVID-19 影响的患者中地理上确定的 SARS-CoV-2 变体特别有益。
