"According to early data published on Tuesday by the ONS, the triple-vaccinated are 4.5 times more likely to test positive for a probable Omicron infection than the unvaccinated.
The double-vaccinated, meanwhile, are 2.3 times more likely to have a probable Omicron infection.
This data from the ONS Infection Survey, while provisional, adds support to the claim that the Omicron variant has significant vaccine evading ability.
This means it doesn’t tell us that the vaccines are making things worse overall, only that they are making it much more likely that a vaccinated person is infected with Omicron than another variant.
In other words, it is a measure of how well Omicron evades the vaccines compared to Delta.
The fact that the triple-vaccinated are much more likely to be infected with Omicron than the double-vaccinated confirms this vaccine evading ability.
The data also doesn’t tell us anything about the severity of Omicron, or how well the vaccines continue to protect against serious disease.
It does mean, though, that Omicron is largely an epidemic of the vaccinated and is being driven, not by the unvaccinated, but by those who have been double and triple jabbed."
