Immunization, Vaccines and Biologicals

Immunization highlights: 2010

Global trends in immunization

More children than ever before benefited from vaccination

In 2009, out of the estimated 130 million annual surviving infants, the number of children under age one vaccinated with three doses of diphtheria-tetanus-pertussis (DTP3) vaccines reached 107 million, 14.6 million more than in 2000. These children are protected against a number of infectious diseases that can have serious consequences in terms of illness and disability or can be fatal.

More countries achieve high levels of vaccination coverage

Global Immunization Data graph

The number of countries reaching 90% or more DTP3 coverage in 2009 was 122, compared with 119 in 2008.

The number of countries reaching 80% or more DTP3 coverage in 2009 was 157, compared with 154 in 2008.

Access to new and underused vaccines is increasing

The number of countries using specific vaccines by the end of 2009 was:

  • Haemophilus influenzae type b (Hib) vaccines: 161
  • Hepatitis B vaccines : 178
  • Human papillomavirus (HPV) vaccines: 27
  • Pneumococcal vaccines: 44
  • Rotavirus vaccines: 23
  • Rubella vaccines: 130
  • Tetanus vaccines: over 100 countries (maternal and neonatal tetanus persist as public health problems in 42 countries, mainly in Africa and Asia)
  • Yellow fever vaccines: 35 countries and territories (out of the 45 at risk for yellow fever in Africa and the Americas)

Challenges remain

Despite these successes, the immunization agenda has not been fulfilled, and unprecedented opportunities and challenges lie ahead.

An estimated 23 million infants worldwide are still not being reached by routine immunization services. Seventy percent of these children live in ten countries and more than half of them live in India and Nigeria.

Several large countries such as China, India, Indonesia and Nigeria have not yet introduced Hib vaccine.

Rotavirus vaccine is available in 23 countries, covering only 11% of the estimated 136 million infants born worldwide in 2009.

Pneumococcal vaccine is available in 44 countries, covering 11% of infants born in 2009.
