Use of the 13-valent pneumococcal conjugate vaccine reduced the incidence of invasive pneumococcal disease and related deaths in Denmark, according to recent findings.

Notably, the decrease in invasive pneumococcal disease (IPD)-specific mortality was related to decreased disease incidence in the non-vaccinated population, researchers wrote.

The researchers found that after the introduction of PCV13, there was a 21% decrease in the incidence of IPD in the general population and a 71% decrease in children younger than 2 years.

There was also an approximate 28% decrease in 30-day mortality specific to IPD. This rate went from 3.4 deaths per 100,000 population before PCV introduction to 2.4 after the introduction of PCV13.
