Omicron variant,[1] also known as B.1.1.529,[2] is a strain of SARS-CoV-2[3] first discovered in South Africa in late November 2021 with reported cases in several other countries. Currently, reportedly little is known about the mutations comprising Omicron.[4]
Several countries have banned travel with South Africa, prompting sharp criticisms due to the fact that scientists in South Africa had discovered the variant with advanced genome sequencing; the nation's Ministry of International Relations and Cooperation responded:[4]

Incumbent White House officeholder Joseph R. Biden, who called travel bans "racist" and "xenophobic,"[5] imposed a travel ban on eight African countries[6] based on recommendations of medical advisers led by Anthony Fauci.[7]
Pfizer/BioNTech Vaccine Effectiveness
With a press release from Pfizer dated December 08, 2021, preliminary laboratory studies demonstrate that three doses of the Pfizer-BioNTech COVID-19 Vaccine neutralize the Omicron variant (B.1.1.529 lineage) while two doses show significantly reduced neutralization titers.[8]
Genome
The Omicron variant is unlikely to be related to the Alpha and Delta variants of coronavirus.[3] Instead, its mutations cause it to be distinct from the other strains of the virus. The mutations are likely to make the Omicron variant ineffective to combat by COVID-19 vaccines, due to a potentially different "Spike" gene (associated with 32 different mutations) the vaccines are designed to target.[3]
