Omicron Variants
Omicron B.1.1.1.529 is a variant of SARS-CoV-2. The Network for Genomics Surveillance first reported this variant in South Africa in November 2021. The first
case was detected in Botswana and has now spread around the world to become a major variant in circulation.
In addition to the original BA.1 variant, several subvariants such as BA.2, BA.3, BA.4, and BA.5 have
emerged over time. To prevent serious illness and hospitalization caused by the BA.1 and BA.2
variants of Omicron, 3 doses of the COVID-19 vaccine are provided. The BA.4 and BA.5 variants are more contagious than the other sub variants.
