Antibody News and Research

RSS

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.

Increased Fucose Digestion by Gut Bacteria Linked to Lower Immune Responses to COVID-19 Vaccine

Gut bacteria that break down a sugar called fucose could be dampening our immune response to the COVID-19 mRNA vaccine, according to a study led by researchers from the Okinawa Institute of Science and Technology.
