Which vaccination has led to a decrease in cases of epiglottitis?

The Haemophilus influenzae type b (Hib) vaccine has significantly contributed to the decrease in cases of epiglottitis, particularly in children. Prior to the widespread use of the Hib vaccine, Haemophilus influenzae type b was a common cause of bacterial epiglottitis, which can lead to severe respiratory distress.

The introduction of routine vaccination against Hib has led to a dramatic reduction in the incidence of epiglottitis caused by this organism. This vaccine helps the immune system to recognize and fight off Hib bacteria, thereby preventing infections associated with it, including epiglottitis.

Other vaccines mentioned, while important for preventing various infections, do not specifically target the pathogens commonly associated with epiglottitis in the same manner as the Hib vaccine. Thus, the Hib vaccine is specifically linked to the decline of epiglottitis cases due to its effectiveness against the responsible bacteria.
