WHO's Chief Scientist Dr Soumya Swaminathan said that existing vaccines will likely prevent disease and death. According to the scientists, it is "highly likely" that Omicron can escape immunity caused by previous infection or vaccination because of the presence of over 30 mutations on its spike protein, which binds to human cells, associated with higher transmission, and a decrease in antibody protection.
