👉 Nondiphtheritic is a term used in medicine to describe an organism that has not been vaccinated or infected with a specific disease. This condition can occur when an individual does not receive enough vaccination before they are exposed to a particular pathogen, such as diphtheria, tetanus, or pertussis (whooping cough). In this case, the immune system may be unable to effectively fight off the infection and the individual is considered to have a "nonimmune" response.
