At the same time, other mutations are thought to, to the Centers for Disease Control and Prevention, suggests omicron is likely to have increased transmission compared to the original SARS-CoV-2 virus, but it is difficult to infer if it is more transmissible than Delta., of COVID-19 cases in South Africa, which appears to be, due to omicron, also suggests the variant could be more contagious.

Even if boosted antibodies have some reduction in efficacy against omicron, the substantially higher antibodies levels generated after the boost are expected to perhaps offset slightly lower neutralization capacity. But, he acknowledged, whether that will be true isnt yet known. coronavirus transmission, also making it difficult to say whether omicron can necessarily outcompete delta, either because of increased transmissibility or immune evasion.
