Studies are underway in test tubes and animals to determine whether the new Omicron variant of the coronavirus can slip past the immune protection of vaccination or a previous infection.
Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said the results from tests of disabled and live Omicron viruses mixed with the serum -- the clear part of the blood -- of vaccinated or previously infected people should be ready next week.
Fauci, speaking at a briefing of the White House COVID-19 Response Team, says data shows the Omicron variant has swiftly become the main cause of new COVID-19 infections in South Africa.The situation in South Africa is not exactly the same as what’s happening in the U.S. South Africa has not been able to vaccinate as many people as the U.S. has.
“It’s too early to be able to determine the precise severity of disease … but it appears with the cases we are seeing, we are not seeing a very severe profile of disease,” he said. But he cautioned that this data could be biased because the earliest cases in South Africa have been reported in younger people, who tend to have less serious cases anyway.CDC Director Rochelle Walensky, MD, said teams working to track the spread of Omicron after the large Anime 2021 conference in New York City have been able to contact about 35,000 of the 53,000 people who were estimated to have attended.

Fauci says early evidence points to Omicron being more transmissible but less severePreliminary evidence indicates that the Omicron variant of the coronavirus likely has a higher degree of transmissibility but is less severe, top U.S. infectious disease expert Anthony Fauci said on Tuesday. Although more data is needed, early cases of Omicron seem to require fewer hospitalizations and patients are less likely to need oxygen, Fauci told reporters at a White House briefing. More data is expected next week, Fauci said, but it will take a few weeks to reach any definitive conclusions.
