Positive affinity and varied solvent accessibility will create negative impacts on the vaccine and diagnostic test development. expected 9-mer (e.g., GAEGFNCYF epitope) in which the MHC I can bind effectively to the mutant strain. Positive affinity and varied solvent accessibility will create negative impacts on the vaccine and diagnostic test development. In a recent study, the multi-epitope vaccine designed using DeepVacPred software effectively binds for mutant strain [36]. Although carefully selected therapeutic cocktails will offer greater resistance to SARS-CoV-2 escape, this identified mAbs will significantly help in the preclinical evaluation and development of immune therapeutics to be used against COVID-19 in humans [37]. Since mutations bring about changes only in the spike protein structure without any differences in the ACE2 receptor moiety, it is predicted that vaccines developed to bring around humans immunogenicity in fighting the virus cannot be affected by, except if there are any aggressive mutations. The V483A has not been reported as an aggressive mutation, although it is one of the most important mutations after the D614G mutation [21]. In any case, exploring the complete nature of the virus along with each of its mutant strains has always been of paramount importance in designing an effective vaccine and for meaningful therapeutic treatments [7]. A list of protein-based vaccines currently undergoing clinical trial has been given in the table below (Table?3). Table 3.

Data taken from [38]. Conclusion The V483A mutation represents one of the major emerging mutations of the current COVID-19 pandemic crisis. We found that significant attention has been given by various researchers globally to this particular variant. Data from high-quality research works were coordinated and critically reviewed in all sections of this review. Evidence from different researchers worldwide shows that the next emerging mutation after D614G can severely enhance the infection rate. V483A is not directly related to the virusChost cell interaction, but it can improve the proteinCprotein complexs binding stability and binding capacity. We observed that the V483A.
