VoICE Immunization Evidence: Educational Attainment
Key Evidence: In a study of children in a Brazilian shantytown, researchers found that the greater the number of episodes of persistent diarrhea before age two, the more delayed a child was in terms of school readiness. Overall, each episode of diarrhea delayed a child’s starting school by 0.7 months. Likewise, 6-10 years later, increasing episodes of diarrhea before age two predicted delays in age-appropriate educational attainment.
Survivors of potentially vaccine-preventable tuberculous meningitis have a high school failure rate.
Key Evidence: Children in Western Cape, South Africa who were well enough to attend school after surviving tuberculosis meningitis, more than half had failed at least one school grade.
Key Evidence: This study follows up on a 1974 randomized trial of tetanus and cholera vaccine administered to mothers in Bangladesh. At the time of follow up in 1996, there was a clear pattern of increased educational attainment among children whose mothers received tetanus vaccine during pregnancy. This pattern was significant for the group of children born to vaccinated mothers with very low levels of education.
Key Evidence: For every 6 children vaccinated against measles in a poor, largely rural community in South Africa, one additional grade of schooling was achieved.
