The coronaviruses (CoV) show great diversity with respect to their genomic structures and the ability to infect animals and human beings. Multiple omics studies have been conducted to understand and identify the genome organization, immunological responses, and molecular markers for vaccine and drug development. However, due to constant mutational changes in the CoV-2 genome, the drug and vaccine development is becoming a challenge to target new variants. A tremendous amount of research is being carried out for vaccine development by utilizing bioinformatics and immunoinformatics, however, most of the developed vaccines are under trial. In this review, SARS family members are systematically illuminated for their differences, infections and mechanism of action along with recommendations to counter the new variants of CoV-2 through multi-omics, machine learning and structural bioinformatics techniques.
