A new study has revealed that the vast majority of individuals infected with mild-to-moderate Covid-19 mount a robust antibody response that is relatively stable for at least five months.
The study, published in the journal Science, found that this antibody response correlates with the body’s ability to neutralize the virus that causes Covid-19.
“We have found just the opposite – that more than 90 per cent of people who were mildly or moderately ill produce an antibody response strong enough to neutralize the virus, and the response is maintained for many months,” said study author Florian Krammer from Mount Sinai Hospital in the US.
“Uncovering the robustness of the antibody response to SARS-CoV-2, including its longevity and neutralizing effects, is critically important. This is essential for effective vaccine development,” Krammer added.
Study findings are based on a dataset of 30,082 individuals, who were screened within the Mount Sinai Health System between March and October 2020.
However, recently, a study from Imperial College London found that antibodies against Covid-19 declined rapidly in the hundreds of thousands of people across England.
