Analyzing the antibodies in blood samples taken from study participants on the day of their coronavirus test and 28 days later, the researchers ferreted out some notable differences between those who developed severe symptoms and those who didnt. But those who had antibodies were less likely to have COVID-19 as time went on. IgG levels against receptor binding domain of spike protein (anti-S-RBD IgG) in PCR-positive and/or vaccinated individuals and not PCR-positive, not vaccinated, but seropositive individuals. Blood drawn from patients shortly after they were infected with SARS-CoV-2, the virus that causes COVID-19, may indicate who is most likely to land in the hospital, a study led by Stanford Medicine investigators has found.
