In children older than 15 and 18 months, the Hib and DTaP vaccines are being combined in a single injection. Of note: evidence suggests that in infants, this combined vaccine using acellular pertussis (the current DTaP standard) is less effective in protecting against Hib than one that uses the older form with whole cell pertussis. The booster at one year should help maintain protection, however.

The Hib vaccine may benefit older people who have had their spleen removed or illnesses that put them at risk for pneumonia, including sickle cell disease, leukemia, and HIV infection.
