Omicron itself, however, is much newer, as current estimates indicate it began circulating in people only around, Or, the variant may have evolved in one or more immunocompromised people, such as a person with HIV. . mutations in its spike gene that are predicted to make neutralizing antibodies less effective, suggesting the variant could have an easier time reinfecting people who have recovered from COVID-19 and infecting vaccinated people. The real risk of severe disease, hospitalization and death lies in particularly at-risk and vulnerable individuals who do require protection against all variants of COVID-19.. Miller notes that a small preprint paper out of South Africa, which has not yet been peer-reviewed, suggested that more detectable virus may reside in the throat than in the nose when a person is infected with omicron compared to the delta variant, though the study compared PCR to antigen, or rapid, tests, which are not the same type of tests.
