The article examines modern strategies of vaccination prophylaxis in industrial poultry farming. Various types of vaccines are analyzed – from traditional live attenuated and inactivated to innovative vector platforms. Methods of vaccine administration are presented, including aerosol immunization and in ovo technology. The role of maternal antibodies in post-vaccination immunity formation and the importance of serological monitoring for evaluating vaccination program effectiveness are considered. Modern approaches to immunization against highly pathogenic avian influenza using marker vaccines and DIVA strategy are analyzed. It is shown that successful vaccination prophylaxis is only possible with a comprehensive approach that takes into account biosecurity of production, proper selection of vaccines and optimal schemes of their application. Biosecurity remains a fundamental condition for the effectiveness of any immunization programs.
