  A recent study on more than 365,000 randomly selected people in England with home finger-prick testing, published by Imperial College London and Ipsos MORI, a market research company revealed that there was a more than 26% significant decline in SARS-CoV-2 (COVID-19) antibodies over three months. The investigators observed more than three rounds of the national surveillance by using a self-administered lateral flow test at 12, 18 and 24 weeks after the first peak of SARS-CoV-2 (COVID-19) infections in England. These findings on SARS-CoV-2 (COVID-19) that individuals’ detectable antibody levels followed in longitudinal studies that decreased over time are consistent with evidence that immunity to seasonal coronaviruses decreases over 6 to 12 months after infection. At the beginning of the study, in June 2020, 6% of the tested people had IgG antibody responses to SARS-CoV-2 (COVID-19) and by September 2020, only 4.4% of them had. The rates of IgG antibody responses among the healthcare workers were the same. The tests were not designed to detect other types of antibodies that may persist longer than IgG antibody responses does.
