The development of a vaccine will rely either on the direct administration of viral antigens (e.g., in the form of recombinant proteins, vectored vaccines, or whole inactivated or attenuated virus) or RNA- or DNA-encoding viral antigens.27 Candidate antigens for immunization are surface proteins such as the immunogenic spike protein (S1), which is already targeted by antibodies of convalescent patients.27 Because the S1 protein is also essential for cellular uptake, many researchers are using this protein as the primary target for a vaccine. |
