The Omicron coronavirus variant, reported in more than 60 countries, poses a 'very high' global risk, with some evidence that it evades vaccine protection but clinical data on its severity is limited, the World Health Organization says. Considerable uncertainties surround Omicron, first detected last month in southern Africa and Hong Kong, whose mutations may lead to higher transmissibility and more cases of COVID-19 disease, the WHO said in a technical brief issued on Sunday. 'The overall risk related to the new variant of concern Omicron remains very high for a number of reasons,' it said, reiterating its first assessment of Nov. 29. At least one patient has died in the United Kingdom after contracting the Omicron variant, British Prime Minister Boris Johnson said on Monday.

At least one patient has died in the United Kingdom after contracting the Omicron variant, British Prime Minister Boris Johnson said on Monday. Corroborating the WHO's assessment, University of Oxford researchers published a lab analysis on Monday that registered a substantial fall in neutralising antibodies against Omicron in people who had had two doses of COVID-19 vaccine.

Both the Innsbruck and the Oxford teams said they would widen their research to those who had three vaccine shots. The WHO cited preliminary evidence that the number of people getting reinfected with the virus has increased in South Africa.
