Antibodies are an immune response that linger in the blood of people who’ve recovered from a disease. That’s also how vaccines work—they teach the body how to produce those antibodies so it’s ready the next time the disease comes around. There’s no vaccine for COVID-19 yet, but scientists have developed blood tests that can identify antibodies against coronavirus. In KNAU’s weekly update on the science of COIVD-19, Melissa Sevigny spoke with infectious disease expert Dr. Paul Keim about why these antibody tests matter for public health, and what it means when the results say someone is “sero-positive.”
