he new variant B.1.1.529 of the SarS-CoV2 virus isolated in South Africa, which with its 32 discovered mutations surpasses those of the Delta, worries the world. WHO has named it Omicron, classifying it as “worrying”. The possibility that it is much more contagious than the others and that it will be able to neutralize the effectiveness of vaccines is arousing strong fears.
The European Center for Disease Prevention and Control (ECDC) has provided some preliminary information that Omicron could be associated with very high transmissibility, weakening the action of vaccines but not a more serious infection. The European Medicines Agency (EMA) has in fact stated that for the moment it is “premature” to predict whether an adaptation of vaccines is necessary for B.1.1.529.
