Potent antibodies found in people recovered from COVID-19Potent antibodies found in people recovered from COVID-19

The researchers first isolated antibodies that could bind to the receptor binding domain (RBD), a crucial region on the virus’s spike protein. They then tested whether the antibodies could neutralize SARS-CoV-2—that is, bind to the virus and stop infection.

Most participants had low or very low levels of antibodies against SARS-CoV-2. Only 1% of the study participants had high levels of antibodies that could neutralize the virus.
