The risk of Omicron infection increases dramatically with the number of vaccine doses, by up to 300% for three or more doses, a study has found, in one the most striking illustrations of negative vaccine efficacy yet to emerge.

The study, which is not yet peer-reviewed, gathered data on infection rates among employees of Cleveland Clinic in Ohio from September 12th to December 12th 2022. The primary aim was to study the effectiveness of the new bivalent COVID-19 vaccine, which it found to be just 30% effective against infection during the study period.
