NCIt synonyms : Adenovirus Type 5-encoding SARS-CoV-2 Spike Protein; Ad5-encoding SARS-CoV-2 Spike Protein Vaccine; Ad5-nCoV COVID-19;
NCIt definition : A recombinant, replication-deficient coronavirus vaccine composed of a genetically
engineered adenovirus type 5 (Ad5) vector that expresses full-length SARS-CoV-2 spike
protein (SP), with potential immunomodulating and anti-COVID-19 activities. Upon intramuscular
administration of the Ad5-nCoV vaccine, the Ad5 infects human cells, which produce
the SARS-CoV-2 SP, and travel to the lymph nodes where the immune system creates anti-SARS-CoV-2
SP antibodies. The antibodies recognize 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.;
