Immunogenetics is the study of the genetic basis of the immune response. It involves the study of how genes influence the immune system's ability to recognize and respond to foreign substances such as pathogens or antigens. Researchers in this field aim to understand how genetic variations can impact an individual's susceptibility to immune-related diseases, response to vaccination, and overall immune function. By studying the genetic aspects of the immune system, immunogenetics can provide insights into the development of personalized therapies and treatments for various immune-related disorders.
