Evidence antibodies targeting HCoV-OC43 are robustly boosted in response to SARS-CoV-2 but not vaccination.Taken together, all of these variants have been classified on the basis of genomic sequencing, specifically related to the coding regions in the spike (S) protein within the SARS-CoV-2 genome. Comparatively, some strains with more serious mutations were labeled as variants of concern (VOC) like the Alpha (B.1.1.7/Q), Beta (B.1.351.1,2,3), Delta (B.1.617.2/AY), and Gamma (P.1.) variants. The presence of these mutations led to some of them being labeled variants of interest (VOI), like the Eta (B.1.525), Iota (B.1.526), and Kappa (B.1.617.1), depending on preceding factors. Study: Near-Complete Genome of SARS-CoV-2 Delta (AY.3) Variant Identified in a Dog in Kansas, USA. As the world went into lockdown, molecular genetics research familiarized the public with different mutations undergone by the (SARS-CoV-2). In late 2019, a novel severe acute respiratory syndrome coronavirus (SARS-CoV-2) emerged in Wuhan, China, and has since become one of the most economically impactful pandemics to date.
