Did you Know ?
Before the introduction of the Hib vaccine, H. influenzae type b (Hib) was a major cause of meningitis and other severe infections in children under the age of 5. The Hib vaccine has been highly effective in preventing these infections, leading to a dramatic decline in Hib-related diseases.
