By evaluating different vaccines in different farm environments, key factors affecting immunization outcomes were identified, and the economic benefits of effective vaccination programs were quantified. The study showed significant differences in vaccine performance, highlighting the importance of optimizing vaccination plans and improving farm management practices, and emphasizing the necessity of continuously improving vaccination strategies and integrating technological advances to enhance efficacy. This study aims to emphasize the key roles of biological, environmental, and operational factors in shaping vaccine performance, providing practical recommendations for policymakers and poultry farmers to strengthen immunization programs and improve poultry health and productivity. Keywords Poultry vaccination; Vaccine efficacy; Field trials; Poultry farm management; Immunization strategies 1 Introduction Poultry farming is a critical component of the global agricultural industry, providing a significant source of protein through meat and eggs. However, the industry faces numerous challenges, including infectious diseases that can lead to substantial economic losses. Vaccination is a key strategy in managing these diseases, ensuring the health and productivity of poultry flocks. Poultry vaccination has been a cornerstone in the fight against infectious diseases such as Newcastle disease, avian influenza, and fowl cholera. These diseases can spread rapidly and cause high mortality rates if not controlled effectively. Traditional vaccination methods, such as inactivated and live vaccines, have been employed to induce immunity in poultry, with varying degrees of success depending on the disease and the vaccine used (Hsu et al., 2010). Recent advancements have introduced recombinant vaccines and novel delivery methods, such as spray and oral administration, which are particularly beneficial for smallholder and rural poultry producers (Mebrahtu et al., 2018; Khantour et al., 2021). The importance of poultry vaccination cannot be overstated, as it plays a crucial role in maintaining the health of poultry populations and ensuring food security. Effective vaccination programs can significantly reduce morbidity and mortality rates, thereby enhancing productivity and profitability for poultry farmers (El-Shall et al., 2021; Samakkhah et al., 2023). Moreover, vaccination helps in controlling the spread of zoonotic diseases, thereby protecting public health. For instance, vaccines against avian influenza not only protect poultry but also reduce the risk of transmission to humans (Kuruppuarachchi et al., 2022). This study analyzed the efficacy of various vaccines used in poultry farms, with a focus on field trials of chicken immunity. By evaluating different vaccination strategies and their outcomes, insights were provided for the most effective methods of poultry disease prevention, including examining the protective efficacy of vaccines against common poultry diseases, evaluating the impact of different delivery methods, and understanding the role of vaccination in improving poultry health and farm productivity. This study aims to contribute to the development of more effective vaccination plans through analysis, which can be implemented under different agricultural conditions.
