A wide range of vaccines against common poultry diseases are now available for in ovo administration globally – although availability varies from country to country. Recent developments from Pfizer Global Poultry include the first antigen-antibody complex vaccine (Bursaplex) for in ovo use against infectious bursal disease (IBD), and a live oocyst vaccine for coccidiosis (Inovocox EM1).
Through the use of recombinant DNA techniques, the number of poultry diseases that can be protected against using the in ovo route is likely to increase significantly over the next few years. A number of such vaccines are currently in development at Pfizer Global Poultry.
