Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has devastated the world with coronavirus disease 2019 (COVID-19). SARS-CoV-2 is an RNA virus that has a high mutation rate producing a new variant with serious threats. Recently emerged delta variant (B.1.617.2) (India), and omicron (B.1.1.529) (South Africa) mutant makes more serious attention than others previously known. These variants exhibit many neurological complications. The new variants of COVID-19 are also involved in gut microbiota dysbiosis, thus enhancing inflammation process which in then causes stroke, diabetes and thrombosis. Administering vaccines is crucial due to continual mutation and the introduction of variants of concern. Therefore, variant modified vaccines have been thought of as potential vaccines.
