Over half of UK Omicron cases happened after two jabs – as UKHSA releases risk assessment
The UK Health Security Agency gives red status to concerns about naturally acquired immunity, vaccine-derived immunity and therapeutics.
More than half the confirmed cases of the new Omicron variant in the UK were double jabbed, health officials have said.
A new technical briefing from the UK Health Security Agency (UKHSA) says 12 of the 22 known cases up to 30 November had been fully vaccinated.
Another two people infected had been given their first dose at least four weeks earlier.
Six were unvaccinated, with no data available on two of the cases.
However, the data does not tell us how well the vaccine protects against Omicron.
