European Medicines Agency's (EMA) executive director Emer Cooke said the agency needs more data on vaccine efficiency, the variant's transmissibility and the severity of disease it causes.

An official at the EU agency warned however against "a drop in the ability of the vaccine to exert due neutralisation for omicron."

Asked to comment about a study released earlier on Tuesday suggesting some women had heavier periods after being inoculated, the EMA said it had not established a link between changes in menstrual cycles and COVID-19 vaccines.
