Antibodies last over a year after COVID-19 infection, according to study
Those who experienced severe infection had higher levels of antibodies.
Most people who have been infected with SARS-CoV-2, the virus that causes COVID-19, will carry antibodies for at least a year, according to a recent peer-reviewed study.
Their findings included 96% of subjects still carrying neutralizing antibodies and 66% with the nucleoprotein IgG antibody.
After randomly selecting 367 subjects from the original cohort who were not yet vaccinated a year following infection, the scientists found that 89% of subjects still had neutralizing antibodies, and 36% with the IgG antibody.
The neutralizing antibodies «were only slightly reduced» in the Alpha variant and «considerably declined» in the Beta variant. However, «over 80% of the subjects who had recovered from severe» SARS-CoV-2 infection still had neutralizing antibodies against the Delta variant a year after being infected.
