Viral vector, composition, vaccine, vaccine composition, kit, processes for the preparation of a viral vector and for the preparation of a composition, use of a viral vector, and method of treatment
The invention relates to a replication deficient simian adenoviral vector C7 encoding a protein comprising CS protein from P. falciparum or a fragment thereof, for example as shown in Seq ID No: 1 or Seq ID No: 3. The invention also relates to processes of preparing said viral vector and use of the viral vector in the treatment/prevention of malaria infection. Compositions, vaccines and kits comprising said viral vector are also described. In one aspect the invention employs a synthetic C7 viral vector. The C7 viral vector according to the invention may be co-administered or co-formulated with a malaria antigen such as RTS,S optionally in the presence of an adjuvant for example comprising 3D-MPL and/or a saponin such as QS21.
