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.
Key Findings
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.
- In Northern Ireland, it is estimated that over 8 in 10 adults, or 85.4% of the adult population (95% credible interval: 82.0% to 88.5%) would have tested positive for antibodies against SARS-CoV-2 on a blood test in the week beginning 7 June 2021, suggesting they had the infection in the past or have been vaccinated.
- In the week beginning 7th June 2021, the percentage of adults aged 16 to 49 testing positive for antibodies ranged from 37.0% to 90.5%; in those aged 50 to 69 it was 96.4% (95% credible interval: 92.6% to 98.2%); and was similarly high for those 70 years and over at 95.7% (95% credible interval: 91.0% to 97.9%).
- The survey provides an estimate of the percentage of people that have been vaccinated however it should be noted that the figures are based on self-report and may differ from official figures which are a more precise count of total vaccines issued.
- The survey estimates will allow for additional analysis of vaccination information with other characteristics, such as testing positive for antibodies.
- The survey shows that in Northern Ireland, an estimated 86.2% (95% credible interval: 84.9% to 87.3%) of the adult population have been vaccinated (at least one dose) against SARS-CoV-2 in the week beginning 7 June 2021.
- In the week beginning 7 June 2021, the survey shows the percentage of people who have been vaccinated against SARS-CoV-2 for those aged 70 years and over was 98.5% (95% credible interval: 97.2% to 99.2%). The percentage in the other age groups ranged from 32.1% to 96.8%.
- The survey suggests an estimated 59.3% (95% credible interval: 57.6% to 61.0%) of adults have been fully vaccinated.
Notes to editors:
1. 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 27th July 2020.
2. 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.
3. These statistics refer to the presence of antibodies to the Coronavirus (COVID-19) and vaccinations within the community population, by which we mean private residential households. These figures exclude those in hospitals, care homes and/or other institutional settings.
4. 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/vaccination data fortnightly.
