Here are some of the latest immunization data available on the WHO website:

Global Immunization Data

Summary: Global immunization coverage in 2012

Immunization currently averts an estimated two to three million deaths every year in all age groups from diphtheria, tetanus, pertussis (whooping cough), and measles.

In 2012, an estimated 83% (111 million) of infants worldwide were vaccinated with three doses of diphtheria-tetanus-pertussis (DTP3) vaccine. Three regions ? the Americas, Europe and Western Pacific ? maintained over 90% DTP3 immunization coverage, the Western Pacific reaching 97%.

Number of countries reaching 80% or more immunization coverage with DTP3 vaccine in 2012: 165 countries compared to 164 in 2011.

Number of countries reaching over 90% or more immunization coverage with DTP3 vaccine in 2012: 131 countries compared to 128 in 2011.

Increasing uptake of new and underused vaccines
Hepatitis B vaccine for infants was introduced nationwide in 181 countries by the end of 2012. Global coverage with three doses of hepatitis B vaccine is estimated at 79% and is as high as 91% in the Western Pacific and the Americas. Coverage in the South-East Asia Region reached 72% in 2012 up from 56% in 2011.

Haemophilus influenzae type B (Hib) vaccine was introduced in 184 countries by the end of 2012 (including in parts of Belarus, India, Maldives and Nigeria), up from 177 countries in 2011. Global coverage with three doses of Hib vaccine is estimated at 45% in 2012, reaching 91% in the Americas, but only 11% and 14% in the South-East Asia Region and in the Western Pacific Region, respectively.

Rubella vaccine was introduced nationwide in 132 countries by the end of 2012, up from 85countries in 1996. There has been remarkable progress towards the elimination of rubella and congenital rubella syndrome in the Americas with a reduction of99.99% of confirmed cases between 1998 and 2012.

Mumps vaccine was introduced nationwide in 120 countries by the end of 2012.

Yellow fever vaccine was introduced in routine infant immunization programmes in 36 countries and territories out of the 48 at risk for yellow fever in Africa and the Americas.

Maternal and neonatal tetanus (MNT): One hundred and three countries provide Tetanus Toxoid-containing vaccine to prevent against maternal and neonatal tetanus (MNT). In these countries, the estimate for the protection of newborns at birth from tetanus that is derived from vaccination coverage
with at least two doses of Tetanus Toxoid vaccine or Tetanus-diphtheria Toxoid vaccine was estimated at 81% in 2012. As of December 2012, maternal and neonatal tetanus persist as a public health problems in 30 countries, mainly in Africa and Asia.
