I heard someone on the radio say some health departments would bring in “PRN” workers to help distribute flu vaccines. What does “PRN” mean?
The phrase comes from the Latin pro re nata. While it literally means something like “for a thing that has been born” in English, PRN commonly refers to health care workers who are hired on an “as-needed” basis. It also can be written on prescriptions to mean the patient should take the medication as needed.
