Among people who were never infected with the new coronavirus, a few adults – and many children – may have antibodies that can neutralize the virus, researchers reported on Friday in Science. Among 302 such adults, 16 (5.3%) had antibodies, likely generated during infections with “common cold” coronaviruses, that reacted to a specific region of the spike protein on the new virus called the S2 subunit. Among 48 children and adolescents, 21 (43.8%) had these antibodies.
