Which vaccine has dropped the incidence of epiglottitis?

• A. MMR
• B. DTaP
• C. Hepatitis B
• D. Hib (Haemophilus influenzae type b)

Answer: (D)

The Hib vaccine is the one that dramatically reduced epiglottitis. Haemophilus influenzae type b used to be the leading bacterial cause of acute epiglottitis in children, a serious airway emergency. vaccinating against Hib lowers both carriage and invasive disease from this organism, so far fewer children develop epiglottitis. Other vaccines listed protect against different diseases (measles/mumps/rubella, diphtheria/tetanus/pertussis, or hepatitis B) and don’t prevent Hib infection, which is why they haven’t changed the incidence of epiglottitis.
