GARCIA-RUIZ, Hernan; LATOURRETTE, Katherine y GARCIA-RUIZ, Mayra Teresa. Basic Coronavirus biology and vaccines for COVID-19. Rev. mex. fitopatol [online]. 2021, vol.39, n.spe, pp.69-87. Epub 30-Nov-2022. ISSN 2007-8080. https://doi.org/10.18781/r.mex.fit.2021-1.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causal agent of the COVID-19 pandemic. Two mRNA vaccines based on the spike protein S have been authorized by the Food and Drug Administration. Antibody-based diagnostic test detect antibodies developed against protein S. Mutations in the genome of SARS-CoV-2 might compromise the precision of diagnostic tests and the efficacy of vaccines and antiviral drugs. We recently profiled genomic variation in human coronaviruses SARS-CoV, SARS-CoV-2, and Middle East respiratory syndrome coronavirus (MERS-CoV). As in all species of the genus Betacoronavirus, the genome is hyper variable, and mutations are not random. The most variable cistron codes for the spike S protein. Hyper variation in protein S has the potential to affect the efficacy of vaccines, the reliability of antibody-based diagnostic test, and predicts potential for repeated SARS-CoV-2 infections. Here we review the basics of coronavirus biology and genomic variation, and link them to diagnostic tests, vaccines, and antiviral drugs.
