Immunogenic compositions and vaccines comprising African swine fever virus peptides and proteins and uses thereof
The present invention relates to African swine fever virus (ASFV) peptides and/or polypeptides as well as immunogenic fragments thereof, corresponding encoding AFSV oligonucleotides and/or polynucleotides as well as immunogenic fragments thereof, immunogenic compositions, vaccines and uses thereof.
1. An immunogenic composition comprising
(a) an African swine fever virus (ASFV) polypeptide MGF100-1L, wherein the MGF100-1L polypeptide is selected from amino acid sequences which are at least 95% identical to an amino acid sequence selected from the group of: (SEQ ID NOS: 572, 570);
or
(b) a heterologous viral or bacterial vector comprising African swine fever virus oligonucleotides encoding African swine fever virus polypeptide MGF100-1L, wherein the MGF100-1L polypeptide is selected from amino acid sequences which are at least 95% identical to an amino acid sequence selected from the group consisting of: (SEQ ID NOS: 572, 570); and
(c) one or more pharmaceutical- or veterinary-acceptable carriers or excipients; and
(d) an adjuvant.
2. The immunogenic composition as claimed in claim 1 , wherein the MGF100-1L polypeptide is selected from the group consisting of: (SEQ ID NOS: 572, 570).
3. The immunogenic composition as claimed in claim 1 , wherein according to (b) the heterologous viral or bacterial vector is selected from the group consisting avipox virus viral vector, canine morbillivirus viral vector, herpes virus viral vector, varicella virus viral vector, Lawsonia spp., Salmonella spp.
4. The immunogenic composition as claimed in claim 3 , wherein according to (b) the heterologous viral or bacterial vector comprises one or two African swine fever virus oligonucleotides which encode African swine fever virus polypeptides, consisting of, an amino acid sequence which is at least identical to an amino acid sequence selected from the group consisting of: MGF100-1L (SEQ ID NOS: 572, 570).
5. The immunogenic composition as claimed in claim 3 , wherein according to (b) the heterologous viral or bacterial vector comprises one or two African swine fever virus oligonucleotides which encode African swine fever virus polypeptides, wherein the one or two African swine fever virus oligonucleotides comprise, a nucleic acid sequence which is at least 95%, identical to a nucleic acid sequence selected from the group consisting of: MGF100-1L (SEQ ID NOS: 573, 571).
6. The immunogenic composition as claimed in claim 1 , wherein the African swine fever virus polypeptide is an African swine fever virus full-length protein.
7. The immunogenic composition as claimed in claim 1 , wherein the African swine fever virus is selected from the group consisting of: BA71, BA71ΔCD2 and/or Georgia2007/1 strain(s).
8. A kit comprising:
(a) a dispenser capable of administering a vaccine to said porcine; and
(b) the immunogenic composition as claimed in claim 1 , and
(c) optionally, an instruction leaflet.
9. The immunogenic composition as claimed in claim 1 , wherein according to (d) the adjuvant is Freund's adjuvant.
