## Abstract

The present invention relates to a recombinant avian herpes virus, which comprises at least two recombinant nucleotide sequences, each recombinant nucleotide sequence encoding a distinct antigenic peptide, wherein the at least two recombinant nucleotide sequences are inserted into distinct non-coding regions of the viral genome chosen among the region located between UL44 and UL45, the region located between UL45 and UL46, the region located between US10 and SORF3, and the region located between SORF3 and US2.

## Claims

### Claim 1

A recombinant avian herpes virus which comprises (i) a recombinant nucleotide sequence encoding a F protein of Newcastle Disease Virus or an immunogenic fragment thereof, under the control of a Pec promoter, inserted into a non-coding region of the viral genome located between UL45 and UL46; and (ii) a recombinant nucleotide sequence encoding a VP2 protein of Infectious Bursal Disease Virus or an immunogenic fragment thereof, under the control of a mCMV IE1 promoter, inserted into a non-coding region of the viral genome located between UL44 and UL45.

### Claim 2 (depends on 1)

The recombinant avian herpes virus of claim 1, wherein the recombinant nucleotide sequence inserted in the region located between UL45 and UL46 is in the same transcriptional orientation as UL46, opposite to the transcriptional orientation of UL45.

### Claim 3 (depends on 1)

The recombinant avian herpes virus of claim 1, wherein the Pec promoter comprises SEQ ID NO: 2.

### Claim 4 (depends on 1)

The recombinant avian herpes virus of claim 1, wherein the mCMV IE1 promoter comprises SEQ ID NO: 19.

### Claim 5 (depends on 1)

The recombinant avian herpes virus of claim 1, which is a recombinant herpes virus of turkeys (rHVT).

### Claim 6 (depends on 1)

A multivalent vaccine which comprises an effective immunizing amount of recombinant avian herpes virus of claim 1.

### Claim 7 (depends on 6)

A method for vaccinating an avian against NDV and IBDV, comprising administering to said avian a multivalent vaccine of claim 6.

### Claim 8 (depends on 6)

A vaccination kit for immunizing avian species which comprises the following components:
a) an effective amount of the vaccine of claim 6, and
b) means for administering said components to said species.
