COVID-19 Vaccine KBP-COVID-19

**Semantic type:** Immunologic Factor|Pharmacologic Substance

**Definition:** A vaccine composed of a recombinant form of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) spike protein (SP) receptor-binding domain (RBD), with potential immunizing activity against SARS-CoV-2. Upon administration of KBP-COVID-19, the SARS-CoV-2 SP activates the immune system to create anti-SARS-CoV-2 SP antibodies. The antibodies recognize and neutralize the SP and kill SARS-CoV-2. This prevents SARS-CoV-2 infection. SP, usually found on the surface of SARS-CoV-2, plays an essential role in the infection pathway of the SARS-CoV-2 virus.
