VoICE Immunization Evidence: Long term disability

Long Term Disability

The Long term disability section contains proof points and evidence related to the abnormal health conditions or diseases related to vaccine preventable diseases. These diseases can be costly to treat and carry long-term consequences for learning, physical functions and future productivity. Visit the Economics, Education and Health Equity sections for more information on some of these consequences.

Key Evidence: Those who experienced more frequent or longer episodes of diarrhea as an infant were more likely to have metabolic syndrome as adults. A longitudinal study in Guatemala found that diarrhea episodes in early infancy are associated with chronic health issues later in life. Each 1% increase in diarrhea burden in children 0-6 months was associated with a 3% increased prevalence in high blood pressure in adulthood. Similarly, a 1% increase in diarrhea burden in older infants 6-12 months was associated with a 4% increased prevalence in elevated waist circumference in adulthood.

Key Evidence: In a study of data from England & Wales, Denmark and the US, it was shown that measles infection suppresses the immune system for up to 3 years after infection, increasing the risk of death due to other childhood infections during that time. This means that prevention of measles significantly impacts overall health during critical childhood years.

Key Evidence: In Gambia, 58% of children who survived a bout of pneumococcal meningitis “had clinical sequelae; half of them had major disability preventing normal adaptation to social life” (mental retardation, hearing loss, motor abnormalities, seizures).

Key Evidence:A systematic literature review analyzing data from 21 African countries revealed that bacterial meningitis is associated with high case fatality and frequent neurophysiological sequelae. Pneumococcal and Hib meningitis contribute to one third of disease related mortality. They also cause clinically evident sequalae in 25% of survivors prior to hospital discharge. The three main causes of bacterial meningitis- Hemophilus influenzae; Streptococcus pneumoniae (pneumococcus) and Neisseria meningitidis (meningococcus) are vaccine preventable, routine use of conjugate vaccines have potential for significant health and economic benefits.
