Coronavirus Antibodies Can Last at Least Four Months, Large Iceland Study Finds

A new study from Iceland provides reassurance that our antibodies to the coronavirus that causes covid-19 can last at least four months—assuming that we produce them in the first

That study looked at blood samples taken from nearly 20,000 people in New York City, home of the single deadliest outbreak of covid-19 reported so far, and found that neutralizing antibodies remained stable for three months.

In both this study and the New York study, roughly 10% of people with confirmed covid-19 seemingly didn’t produce detectable antibodies to SARS-CoV-2, and it’s these people who may be more susceptible to a second infection.

A new study from Iceland provides reassurance that our antibodies to the coronavirus that causes covid-19 can last at least four months—assuming that we produce them in the first place.

But these more pessimistic estimates have come from studies with small sample sizes, while at least one large but preliminary study supports the idea that antibodies can last for months in most people.

The study, published in the New England Journal of Medicine on Tuesday, looked at blood samples collected from over 30,000 people in Iceland, a bit under 10% percent of the small Nordic country’s total population.

And most importantly, they found that the level of antibodies in these survivors did not noticeably drop up to four months after their initial infection. “Our results indicate that antiviral antibodies against SARS-CoV-2 did not decline within 4 months after diagnosis,” the authors wrote.
