Table 2 Incidence in pandemic and non-pandemic years

From: Public health and economic impact of vaccination with 7-valent pneumococcal vaccine (PCV7) in the context of the annual influenza epidemic and a severe influenza pandemic

  Age group (years)
Annual Incidence of PD per 100,000 0 - <2 2 - 4 5 - 17 18 - 49 50 - 64 65+
Incidence of PD in a non-pandemic year (13% influenza incidence)
   Among persons without influenza       
Bacteremic pneumonia 173.0 35.4 3.7 12.1 22.5 58.2
Other pneumonia 4,662 1,501 326 379 1,447 9,200
   Among persons with influenza       
Bacteremic pneumonia 186.3 38.1 4.0 13.1 24.2 62.6
Other pneumonia 5,020 1,616 351 408 1,558 9,906
Incidence of PD in a severe pandemic year (30% influenza incidence)
   Among persons with influenza/a       
Bacteremic pneumonia 2,898 1,688 600 1,192 1,056 4,166
Other pneumonia 6,954 4,006 1,409 2,814 2,491 10,143
  1. PD = pneumococcal disease
  2. a. The incidence of PD among persons without influenza during a pandemic is assumed to be the same as in a non-pandemic year
