Has anyone seen this study published in the Journal of the American Medical Association on the effects of the PREVNAR vaccine?

Excerpt:

CHICAGO—Infants who received heptavalent pneumococcal conjugate vaccination (PCV-7) at 2, 4, and 11 months were more likely than unvaccinated controls to have nasopharyngeal (in the nasal passages and upper part of the throat behind the nose) acquisition of pneumococcal serotype 19A, a leading cause of respiratory pneumococcal disease, according to a study in the September 8 issue of JAMA.

Hmph, I thought this had been known for a while re serotypes 3, 7, and 19A. Hence PCV13. Am I missing the novel part of this study?

PCV13 doesn't cover Serotype 19A either.
