Pneumonia, say the researchers, was the most common clinical disease associated with culture-confirmed invasive pneumococcal disease and this was mostly attributable to serotypes 1, 19A, 3, and 7F.

In fact, one paper Mercola cites, which noted a 71% increase in the prevalence of 19A, also said there had been a dramatic 44% reduction in invasive pneumococcal disease, including pneumonia, meningitis, and bloodstream infections and that includes the increase in 19A. The new vaccine, Prevnar 13, introduced in 2010, protects against the deadly 19A strain, which now appears to be on the wane.
