According to the UK Health Security Agency (UKSA), 12 of the 22 known cases up to November 30 had been fully vaccinated, and two others received first jab 15 days earlier.
Six of the remaining eight positive cases were not vaccinated, while no data available on two of the case.
None of the cases is known to have been hospitalized or died, but the UKHSA said that “most of the cases have a specimen date that is very recent and that there is a lag between onset of infection and hospitalization and death.”
UK has so far confirmed at least 43 Omicron cases, most of them in Scotland, where a gig by pop music group Steps in Glasgow could have been the focus of transmission.
The National Statistics Office (NSO) on Friday announced that despite fears unleashed by the new Omicron variant, the Delta strain continues to be predominant variant in the country, being responsible for 99% of positive cases reported last week.
In the last 24 hours, as many as 50, 584 new cases and 143 deaths were reported, totaling 10.3 million people infected and 145,424 deaths since the beginning of the Covid-19 pandemic.
