Almost everyone in Derry has antibodies to fight COVID-19

Almost everybody in Derry now has antibodies against SARS-Cov-2, according to a new survey.

The Department of Health has reported the results of a new survey that shows that in the week beginning June 13, 2022, 97.9% of the adult population (95% credible interval: 96.3% to 98.7%) would have tested positive on a blood test for antibodies against SARS-CoV-2 at or above 179 nanograms per millilitre (ng/ml).

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.

A DoH bulletin on the survey states: "The presence of antibodies in people in private households is measured to understand who has had coronavirus (COVID-19) in the past, and the impact of vaccinations.

A new survey has found almost 100 per cent have antibodies against SARS-CoV-2.

"It takes between two and three weeks after infection or vaccination for the body to make enough antibodies to fight the infection. Antibodies can help prevent individuals from getting the same infection again. Once infected or vaccinated, antibodies remain in the blood at low levels and can decline overtime."
