COVID-19 antibodies persist at least nine months after infection: Study ANI | Updated: Jul 20, 2021 08:02 IST London [UK], July 20 (ANI): A new study led by researchers at Imperial College London and University of Padua shows antibody levels remain high nine months after SARS-CoV-2 infection, whether symptomatic or asymptomatic. The results of the study were published in the journal Nature Communications. Researchers tested more than 85 per cent of the 3,000 residents of Vo , Italy, in February/March 2020 for infection with SARS-CoV-2, the virus that causes COVID-19, and tested them again in May and November 2020 for antibodies against the virus. The team found that 98.8 per cent of people infected in February/March showed detectable levels of antibodies in November, and there was no difference between people who had suffered symptoms of COVID-19 and those that had been symptom-free.
