The nurse administers DTaP vaccine to an infant. Which level of prevention is this?

Explanation:
Giving a vaccine to an infant is a primary prevention action. Primary prevention aims to prevent disease from occurring in the first place by reducing risk before exposure, and immunizations are the classic example. The DTaP vaccine helps the immune system recognize diphtheria, tetanus, and pertussis so infection is unlikely if exposure happens. This is not about detecting disease early (secondary), nor about treating or limiting damage after disease has occurred (tertiary), and it’s not about avoiding unnecessary interventions (quaternary).
