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 NI for the week beginning 23 May 2022.
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). These latest statistics are based on an antibody test threshold of 179 nanograms per millilitre (ng/ml).
- In Northern Ireland, in the week beginning 23 May 2022, it is estimated that 99.4% of the adult population (95% credible interval: 98.7% to 99.7%) would have tested positive on a blood test for antibodies against SARS-CoV-2 at or above 179 ng/ml.
- In Northern Ireland, in the week beginning 23 May 2022, 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.
Notes to editors:
- The Department of Health has been working along with the Public Health Agency, Northern Ireland Statistics and Research Agency and the Office for National Statistics (and its various survey partners) to extend the COVID-19 Infection Survey to Northern Ireland. Fieldwork in Northern Ireland began on 27 July 2020.
- All results are provisional and subject to revision. Due to the relatively small number of people who tested positive for antibodies within our sample, credible intervals are wide and therefore results should be interpreted with caution.
- These statistics refer to the presence of antibodies to the Coronavirus (COVID-19) within the community population, by which we mean private residential households. These figures exclude those in hospitals, care homes and/or other institutional settings.
- This report is part of the series of Northern Ireland publications from the COVID-19 Infection Survey. Positivity estimates are published on a weekly basis and antibody data fortnightly. Further information can be found on the Department of Health website.
- Further information about quality and methodology associated with the survey can be found on the ONS website.
