The Department of Health today published a report on antibody data from the COVID-19 Infection Survey (CIS).
The findings set out in this report relate to estimates for Northern Ireland for the week beginning 13 February 2023.
This report is part of the series of Northern Ireland publications from the COVID-19 Infection Survey. Further information can be found on the Department of Health website.
In this bulletin, we report percentages of the population that are estimated to have antibodies against SARS-CoV-2, the specific virus that causes coronavirus (COVID-19).
- In Northern Ireland, in the week beginning 13 February 2023, the percentage of people aged 16 and over, estimated to have antibodies against SARS-CoV-2 at or above 800 ng/ml was 74.5% (95% credible interval: 71.3% to 77.6%).
- In Northern Ireland, in the week beginning 13 February 2023, the percentage of the adult population estimated to have antibodies against SARS-CoV-2 at or above the level of 179 ng/ml remained high across all age groups.
- Since January 2023, across most age groups and most UK countries there has been a decrease in the proportion of those estimated to have antibodies to SARS-CoV-2 in the 4,000 ng/ml and above range. The highest antibody levels were seen among those aged 65 years and above across the UK.
Estimates of antibody positivity at 2000 ng/ml, 4000 ng/ml and 6000 ng/ml are presented in the bulletin.
NOTICE: This is the final Coronavirus (COVID-19) Infection Survey antibody data release. As the UK Health Security Agency (UKHSA) works to confirm its approach to surveillance, the Office for National Statistics (ONS) plans to work with existing participants to continue gathering valuable insight into the experiences of COVID-19, long COVID and other respiratory infections, details of which will be announced in due course.
