Which vaccine helped make one of the deadliest childhood diseases far rarer in countries with high coverage?
Quick Answer
The Hib vaccine has made Haemophilus influenzae type b disease much rarer where vaccination is widespread. It protects against meningitis, pneumonia, and epiglottitis in young children.
The Full Story
The Hib vaccine targets Haemophilus influenzae type b, a bacterium that once caused severe meningitis, pneumonia, and epiglottitis in young children. Introduced in the late 1980s and early 1990s in many countries, it dramatically cut invasive Hib disease. Because young children were especially vulnerable, the vaccine became a major pediatric public health success. In places with high coverage, Hib disease has become uncommon.
