Use of codon deoptimisation and optimisation to produce a laryngotracheitis virus-attenuated vaccine

Abstract

An improved method of deoptimization of nucleic acids, particularly nucleic acids associated with genes and/or open reading frames (ORFs) of a variety of pathogens including viruses, retroviruses, bacteria, fungi, and the like. Nucleic acids may be related to genes and/or ORFs from infectious viruses or other diseases and be associated with the elicitation of a protective response when inserted, using recombinant techniques, into a vector and used in a vaccine composition. The nucleic acid sequence of one or more ORFs may be optimized or deoptimized for use in an improved recombinant vaccine to elicit an immune response against an infectious agent when administered to a subject using a variety of dosing and timing regimens.
