The UK Health Security Agency released its first technical briefing on the omicron variant on Friday, but said the delta variant still accounted for over 99% of cases.
Although 12 of the first 22 cases were in people with a double injection, experts warned the numbers were low and reflected basic immunization coverage in the population.
Another 75 cases of omicron have been identified in England, the UK Health Safety Agency said. This brings the total number of confirmed cases in England to 104.
So far, no one with omicron in England has died or been hospitalized. Jenny Harries, Managing Director of the UK Health Security Agency, said: “Thanks to very high levels of vaccine coverage, we already have a strong wall of defense against Covid-19 as new variants emerge.
“We are working as quickly as possible to gather more evidence on any impact the new variant may have on the severity of the disease or the effectiveness of the vaccine.
“Until we have this evidence, we must be extremely careful to draw conclusions about any significant risk to human health.
“The most important thing anyone can do now is get whatever dose of the vaccine you are entitled to – this is by far the most effective step you can take to protect yourself and yourself. your families and communities. ”
