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.

SARS-CoV-2 viral mutations shown to have a limited effect on T cell immunity

New research suggests that viral mutations have a minimal effect on T cell immunity, which could explain the protection provided by vaccination against severe COVID-19, despite the significant loss of neutralizing antibodies.
