VoICE Immunization Evidence: Growth, Development, and Nutrition
Vaccine preventable diseases are linked to poor growth and can further impact an already weakened immune system.
A large longitudinal study in the Philippines found that children suffering bouts of diarrhea and respiratory infections were at a significantly increased risk of physical stunting which is associated with “poor functional outcomes such as impaired cognitive development.”

A prospective case-control study conducted in several developing countries found that children with moderate-to-severe diarrhea grew significantly less in length in the two months following their episode compared to age- and gender-matched controls.

In a study conducted in Southern India, Pneumococcal carriage at age 2 months was associated with a 3-fold risk of stunting and decreased weight, length, and length-for-age by 6 months of age. Pneumococcal carriage at 4 months of age did not affect growth.

A study of Kenyan children under 5 years of age found that children with diarrhea and cough in the 2 weeks prior to the survey were 80-90% more likely to be underweight or to suffer from wasting.
