The introduction of pneumococcal conjugate vaccine (PCV) was linked to a decrease in hospitalizations for sinusitis among children younger than 2 years and pneumonia among children younger than 5 years in a retrospective population-based study in Sweden. The work was published online November 10 in Pediatrics.
Hospitalizations for children with sinusitis dropped from 70 to 24 cases per 100,000 person-years in children younger than 2 years. Hospitalizations for pneumonia in the same age group decreased from 450 to 366 per 100,000 and decreased from 250 to 212 per 100,000 among children aged 2 to 5 years. There was no significant change in hospitalizations among children aged 5 to 18 years.
