Our most recent Coronavirus (COVID-19) antibody and vaccination data for the UK dataset contains our most accurate and up-to-date estimates of antibody positivity. These estimates cannot be compared with those from previous datasets because of changes to how we estimate antibody positivity. More information can be found in our Coronavirus (COVID-19) Infection Survey, antibody data, UK: 29 March 2023 bulletin.

As a result of continued model development, we have produced a revised vaccination estimates dataset for the period 7 December 2020 to 14 November 2021 which aligns the vaccines model formula with that of the antibodies model to allow for better comparison. This data can be found in our revised vaccination dataset.
