Invasive Pneumococcal Disease

Invasive pneumococcal disease (IPD) is caused by the bacteria Streptococcus pneumoniae. It is spread through having close contact with someone who has the bacteria in their nose and mouth, including asymptomatic carriers. IPD occurs when the pneumococcal bacterium invades a normally sterile site (e.g., blood) and can cause pneumonia, sepsis (blood poisoning) and meningitis. In Ontario, pneumococcal vaccines are given in infancy, in older adults and those at increased risk of the disease.

To obtain or inquire about an immunization record, or for general immunization information, please contact your local public health unit.
