To differentiate patients whose fever is most likely secondary to a banal and self-limited infection from those who may have a potentially serious bacterial infection that requires timely and adequate antimicrobial treatment.
To provide information about the different types of vaccines available for children and their indications, contraindications, and efficacy.
