When an antibody binds to the spike protein of SARS-CoV-2, it may block access of the spike protein to the ACE2 protein on human cells. This is one way an antibody can prevent the virus from attaching to and getting inside of human cells. But antibodies can do more than just block virus entry. Due to the symmetrical structure
