Disease information
Haemophilus influenzae b (Hib)
Haemophilus influenzae type b, or Hib,
is an infection that causes pneumonia and meningitis, mostly in
young children.
It spreads by droplet through coughs, sneezing and
in overcrowded living conditions. It is estimated to cause 2 to
3 million cases of disease each year and about 450,000 deaths, the
vast majority of them in developing countries.
Several vaccines against Hib are already in widespread
use in high-income countries, where they have virtually wiped out
the disease. The vaccines, based on conjugates of part of the killed
bacterium and a protein carrier, are among the safest vaccines in
use. Studies have confirmed the effectiveness of these vaccines
in low-income countries, but relatively few of these countries have
begun routine use in infants.
