Pneumococcal Disease

Pneumococcal disease is caused by the bacteria Streptococcus pneumoniae which is responsible for a range of infections, some of which can be life threatening.1

Pneumococcal vaccination helps to protect against invasive pneumococcal disease 2,3

Pneumococcal infections usually fall into one of two categories:4

  • Invasive pneumococcal infections: Occur when bacteria are detected in normally sterile body fluids such as the blood or cerebrospinal fluid.4
  • Non-invasive pneumococcal infections: Occur when there is no evidence that the bacteria has spread to normally sterile body fluids and examples include otitis media (ear infection), sinusitis and pneumonia.4

Invasive pneumococcal infections include: 1


Streptococcus pneumoniae is a common cause of pneumonia in adults.3

Community acquired pneumonia (CAP) is one of the most frequent causes of death from infection in Europe.2 The majority of patients with pneumonia are treated at home but about 1 million are hospitalised annually in the EU.2
