First licensed in 1985, the Hib vaccine protects against H. influenzae type b (Hib), an invasive bacteria that causes epiglottitis, meningitis, pneumonia, septic arthritis, and cellulitis.

A newer Hib vaccine, which could be given to infants, was licensed in 1987
Now all children get their first dose of the Hib vaccine when they are two months old, complete a two to three dose primary series over the next two to four months, and get a booster dose when they are 12 to 15 months old.
