The new Omicron variant of coronavirus has reportedly got over 30 mutations in the spike protein region giving it the potential to develop a immunoescape mechanism, and thus the efficacy of vaccines against it needs to be evaluated critically, AIIMS chief Dr Randeep Guelria has said. The presence of spike protein facilitates a virus' entry into the host cell and is responsible for making it transmissible and causing infection.
