👉 Non-counteractive is a medical term that describes a condition in which an individual's immune system does not recognize or respond to certain types of antigens, such as those from a vaccine. This can lead to immune deficiencies and other health problems if left untreated. The term comes from the Greek word "non" meaning "not," "counteractive" meaning "opposite," and "antigen" referring to an antigen that is part of a vaccine or other immunization method.
