Ear disease, hearing loss, and cognitive outcomes in high school children who were previous participants in a randomized placebo controlled trial of an 11 valent conjugate pneumococcal vaccine administered in infancy

This is the authors' abstract. We don't add key points for this paper.

The WHO estimates that close to 1.7 billion people worldwide have hearing loss; 34 million of whom are children, with 90% residing in low- and middle-income countries. While the effects of ear disease and hearing loss on language, academic, and behavioral development are established, there is remarkably little data on intellectual and other cognitive differences.
