Exceptionally potent antibodies that can neutralize virtually all known variants of the COVID-19 virus—including omicron, as well as other dangerous animal coronaviruses that could potentially cause future outbreaks—have been discovered in a new study just published in Science Advances.

The international team led by Duke-NUS Medical School, with scientists from the National University of Singapore, the University of Melbourne in Australia and other partner institutions, isolated antibodies from the blood of a recovered SARS patient who was thereafter vaccinated against COVID-19. This unique combination of prior coronavirus infection and vaccination generated an extremely broad and powerful antibody response capable of stopping nearly all related coronaviruses tested.
