An antibody is a blood protein that is produced in response to and counteracts an antigen. Antibodies are produced in response to disease and help the body fight against the particular disease. In this way, antibodies help the body develop an immunity to disease.

A mutant SARS-CoV-2 subspecies from minks may evade antibody detection

In a recent research letter published on the bioRxiv preprint server, scientists from Japan discovered that the mutation of spike glycoprotein in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) derived from farmed minks can also be found in the group of individuals with coronavirus disease (COVID-19) and subsequently evade detection by our immune system.

Highly functional immune response in asymptomatic SARS-CoV-2 infection

Researchers in Singapore have conducted a study showing that asymptomatic individuals infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – mount an efficient, balanced and coordinated cellular immune response that protects the host without appearing to trigger any pathological processes.
