The practice of pediatrics in the era of vaccines effective against Haemophilus influenzae type b.

The practice of pediatrics is forever altered when a vaccine is effective in dramatically reducing the incidence of (or even eradicating) an infectious disease. As the targeted disease is rapidly declining in incidence, there are often exciting changes in the practice of pediatrics, with far-reaching effects in the everyday treatment of patients. Such is the case now due to the effectiveness of the conjugated polysaccharide vaccines against Haemophilus influenzae type b (Hib). The resultant rapid decline in the incidence of invasive disease due to Hib during the past several years has been documented in numerous studies.1-3 The effects of this dramatic decline in Hib disease on the approach to children who have (presumed) infectious diseases are the subject of this editorial.
