The researchers said the use of antibodies is similar to the use of convalescent serum from COVID-19 patients, but could be more effective. Convalescent serum contains a variety of antibodies, but because each patient has a different immune response, serum used to treat one patient may be quite different from serum given to another patient, with varying levels and strengths of neutralizing antibodies, the study authors explained.SOURCE: Columbia University Irving Medical Center, news release, July 22, 2020
