WEBINAR: Optimizing protection against infectious bursal disease with live attenuated vaccines

3/2/16 1:00 pm Central European Time

Despite vigorous vaccination strategies, infectious bursal disease virus (IBDV) is still difficult to control. Optimum protection of young chickens against IBDV strongly depends on the effectiveness of the vaccination programs. Depending on the intrinsic characteristics of the existing vaccines or on the vaccination procedures, some of the current vaccination programs may not induce full protection against IBDV under field conditions. As chickens are most susceptible to IBDV in their first weeks of life, an effective vaccination program has to elicit early active immunity to protect properly against IBDV. Therefore, a fast seroconversion is essential in order to reduce the chances of field IBDV infection during the immunity gap that occurs between the days when maternally derived antibodies are still protective and when active immunity becomes fully protective. Although in-hatchery IBDV vaccines have become popular in some regions, live attenuated IBDV vaccines are still a pillar for protection against IBDV and must be considered in our protection plan to ensure an early effective immunization. They mimic IBDV infection, replicate, spread among the flock and quickly induce both cellular and humoral immunity. During this educational webinar learn about how to design effective vaccination programs against IBDV, the best strategies to minimize the risks of vaccination failures and the benefits of using live attenuated IBDV vaccines.  Elanco_logo
