Immunization is one of the most effective ways to prevent infectious diseases after environmental health measures. With effective and timely immunization services, we can reduce the mortality and morbidity rates due to infectious diseases at all ages, especially in childhood. Nurses have an effective role in providing immunization services in primary health care institutions. A quiz competition on immunization was organized within the scope of the public health nursing course to increase students' knowledge about immunization and increase their effective learning and interpretation skills.
