Aug 16, 2021 · In the Oxford-AstraZeneca vaccine, an extended form of the tPA signal sequence (containing the tPA propeptide) was engineered in front of the authentic S protein signal sequence 65,77,78 (Fig. 5b), based on a previous study with Middle East respiratory syndrome coronavirus (MERS-CoV 79 (Fig. 5b).
The vaccine expresses the SARS-CoV-2 spike protein gene, which instructs the host cells to produce the protein of the S-antigen unique to SARS-CoV-2, allowing the body to generate an immune response and to retain that informaion in memory immune cells.
