ChAdOx1

[1] Adenoviruses are effective vectors for inducing and boosting cellular immunity to encoded recombinant antigens.

The former, encoding a malaria liver-stage dual antigen LS2 (LSA1 and LSAP2) fused with the transmembrane domain from shark invariant chain.

And the latter, a Modified Vaccinia Ankara (MVA) vector encoding the LS2 fused to the C-terminal end of the leader sequence of tPA.

[12][13][14][15] Sarah Gilbert leads the work on this vaccine candidate alongside Andrew Pollard, Teresa Lambe, Sandy Douglas, Catherine Green and Adrian Hill.

[16] The COVID-19 vaccine, known now as ChAdOx1 nCoV-19 or AZD1222, makes use of this vector, which stimulates an immune response against the coronavirus spike protein.
