A flu clinic RN travels to flu clinics, such as those set up at pharmacies or high schools, or works at a medical center or hospital flu clinic. In this career, your job is to administer the influenza vaccine to patients. This is typically a temporary job or a side job during flu season for RNs or other nursing and health care professionals who have experience with intramuscular injections. In addition to administering shots, your duties include properly storing and disposing of used materials and providing each patient with advice or educational material related to the flu. Your responsibilities also include ensuring patient privacy and documenting flu shot administration.
