Monoclonal antibodies will be able to complement vaccines by offering rapid protection against infection. Nevertheless, the virus can sometimes manage to outmaneuver such therapies. Antibodies that bind to the spike protein are called neutralizing antibodies, because theyre able to prevent SARS-CoV-2 from entering cells and replicating, thus neutralizing the infection. They may also affect the severity of the disease caused by the virus, or the viruss ability to evade the immune system. .
