SARS-CoV-2 Omicron variant of concern (VOC) has rapidly expanded worldwide since it first emerged on November 24, 2021, in Southern Africa and has already reached every continent. Many issues surrounding Omicron remain unresolved, including the severity of the disease and the extent to which currently available vaccinations effectively prevent COVID-19 infection. Compared to the previous VOC (Delta version), more mutations were detected, which may address Omicron’s characteristics.
