The CDC is urging people 50 and older to get a COVID booster vaccine after the FDA has given their approval for the use of booster doses of both the Moderna and Pfizer COVID-19 vaccines for everyone over 18.

Lawrence Young, a virologist at the University of Warwick, described omicron as “the most heavily mutated version of the virus we have seen,” including potentially worrying changes never before seen all in the same virus. Sharon Peacock, who has led genetic sequencing of COVID-19 in Britain at the University of Cambridge, said the data so far suggest the new variant has mutations “consistent with enhanced transmissibility,” but said that “the significance of many of the mutations is still not known.”

The variant appears to have a high number of mutations - about 30 - in the coronavirus’ spike protein, which could affect how easily it spreads to people. That means people who contracted COVID-19 and recovered could be subject to catching it again. Why Are Scientists Worried About This New Variant?Īfter convening a group of experts to assess the data, the WHO said that “preliminary evidence suggests an increased risk of reinfection with this variant,” as compared to other variants. Now, as many as 90% of the new cases in Gauteng are caused by it, according to Tulio de Oliveira, director of the KwaZulu-Natal Research Innovation and Sequencing Platform. Struggling to explain the sudden rise in cases, scientists studied virus samples and discovered the new variant. Health Minister Joe Phaahla said the variant was linked to an “exponential rise” of cases in the last few days.įrom just over 200 new confirmed cases per day in recent weeks, South Africa saw the number of new daily cases rocket to more than 3,200 Saturday, most in Gauteng.
