More than half of Omicron cases in the UK have been in Britons who received the double vaccine, health officials have revealed.

It comes as Omicron cases have more than tripled, with 92 cases detected in the last 24 hours.

Two others received one shot at least four weeks before testing positive, six were unvaccinated, and vaccine data on the other two cases are not available.
There are no known cases of hospitalization or death.
But UKHSA said most of the cases were recent and pointed out that the disparity between the onset of infection and hospitalization and death.
Tonight it is confirmed that there have been another 75 cases reported in the UK, bringing the total to 104.

Dr Jenny Harries, UKHSA’s chief executive, said: “Thanks to very high levels of vaccine coverage, we already have a solid wall of defense against Covid-19 as new variants emerge. .
“We are working as quickly as we can to gather more evidence of any impact the new variant may have on disease severity or vaccine effectiveness.
“Until we have this evidence, we must exercise the highest degree of caution in drawing conclusions about any significant risk to people’s health.”
Professor Rosemary Boyton, of Imperial College London, said: “Available vaccines appear to protect against hospitalization and death, and there is no reason for us to think it won’t. true for any subsequent variation”.
Scientists here estimate that one in every 300 new cases is due to the mutant super strain, which was first reported from South Africa last month.
