The adage “the more, the better”, may be true when it comes to fighting the novel coronavirus.
Scientists have found twin antibodies that neutralize the new coronavirus, each by slightly different mechanisms. Finding a way to use both antibodies simultaneously might be a particularly good way to attack the virus, the researchers say. According to their report on Wednesday in Science, the two antibodies were isolated from a patient who recovered from COVID-19. Both work by attaching to a spike on the virus that helps it break into human cells. Because the antibodies each bind to different places on the spike, a “cocktail” containing both may be more effective than a treatment using either one by itself. The information could also help in development of a preventive vaccine, the laboratory experiments suggest. Furthermore, even if the virus mutates so that one of the antibodies no longer works, the other might still retain its neutralizing activity.
