Imperfect vaccination drives herpesvirus evolution through recombination. Vaccines are used to help control disease caused by herpesviruses in animals, but some vaccination programs may drive the evolution and spread of herpesviruses with increased fitness (transmissibility, replication and virulence) through recombination. This project aims to study an important avian herpesvirus (infectious laryngotracheitis virus) in the natural host (poultry) to gain fundamental knowledge of how vaccination ....Imperfect vaccination drives herpesvirus evolution through recombination. Vaccines are used to help control disease caused by herpesviruses in animals, but some vaccination programs may drive the evolution and spread of herpesviruses with increased fitness (transmissibility, replication and virulence) through recombination. This project aims to study an important avian herpesvirus (infectious laryngotracheitis virus) in the natural host (poultry) to gain fundamental knowledge of how vaccination programs influence the emergence of diverse recombinant viruses, and identify which types of vaccination programs are best at preventing the emergence of fitter and more virulent viruses. The results are expected to inform vaccination practices to allow more effective control of these viruses in poultry and other animals.Read moreRead less
