The World Health Organization (WHO) has updated its fact sheet on immunization coverage.
Immunization prevents illness, disability and death from vaccine-preventable diseases including cervical cancer, diphtheria, hepatitis B, measles, mumps, pertussis (whooping cough), pneumonia, polio, rotavirus diarrhoea, rubella and tetanus.
Annually, an estimated 2 to 3 million deaths from diphtheria, tetanus, pertussis (whooping cough), and measles are averted due to immunization.
Global vaccination coverage- refers to the proportion of the world’s children who receive recommended vaccines- has remained steady for the past few years.
Vaccine coverage (2014):
DTP3– The proportion of children who received 3 doses of Diphtheria-Tetanus-Pertussis vaccine: 86% (115 million) globally.
Haemophilus influenzae type B (HiB)– The proportion of children who received three doses of HiB vaccine: 56% globally; 90% in the Americas; 30% in South East Asia Region; 21% in Western Pacific Region.
Hepatitis B vaccine– The proportion of children who received 3 doses of Hepatitis B vaccine: 82% globally; 92% in Western Pacific Region
Measles vaccine– The proportion of children who received 1 dose of measles by their second birthday: 85% globally.
Polio– The proportion of children who received 3 doses of polio vaccine: 86% globally. Polio has been stopped in all but 3 countries- Afghanistan, Nigeria and Pakistan.
Tetanus– The proportion of newborn children who were protected through immunization: 83%.
Pneumococcal vaccine: 31% globally
Rotavirus vaccine: 19% globally
More than 60% of the 18.7 million infants worldwide who did not receive routine immunization services like DTP3 vaccine live in 10 countries: the Democratic Republic of the Congo, Ethiopia, India, Indonesia, Iraq, Nigeria and Pakistan, the Philippines, Uganda and South Africa.
Challenges to immunization coverage:
- limited resources;
- competing health priorities;
- poor management of health systems; and
- inadequate monitoring and supervision.
