By the end of 2009, GAVI had helped prevent 5.4 million future deaths through routine immunisation against hepatitis B, Haemophilus influenzae type b (Hib) and pertussis (whooping cough), and one-off investments in immunisation against measles, polio and yellow fever. Many more have been protected against debilitating illness and disability.

Immunisation coverage has climbed steadily in the last decade. Coverage for three doses of the diphtheria-tetanus-pertussis vaccine (DTP3) in GAVI-eligible countries in 2009 is projected at 79% - the highest level ever seen in the developing world. From 2000 to 2009, more than 257 million children have been immunised with GAVI-funded vaccines.
