Rising Cases of Invasive Pneumococcal Disease in Adults Over 50 Spark Warning
Thunder Bay – Health News – The Thunder Bay District Health Unit (TBDHU) is strongly encouraging adults—especially those aged 50 and over—to make sure they are up to date with their pneumococcal vaccination.
The push comes as cases of invasive pneumococcal disease (IPD) continue to rise in the region. So far in 2025, 55% of all reported IPD cases have been in people 50 years of age or older.
Most of these individuals were either not vaccinated or had underlying health conditions like heart or lung disease.
What is IPD and Why the Concern?
IPD is a serious illness caused by the Streptococcus pneumoniae bacteria. It can lead to life-threatening conditions such as pneumonia, meningitis, and sepsis. In many cases, IPD leads to hospitalization.
In fact, 68% of cases in the Thunder Bay District have needed hospital care, and some even required treatment in the ICU.
Who Should Get the Vaccine?
The pneumococcal vaccine, sometimes called the “pneumonia shot,” is a safe and effective way to prevent this illness. According to Ontario’s publicly funded vaccine schedule, the following groups are eligible:
-
All adults aged 65 and older who haven’t had the vaccine yet
-
Anyone with a chronic illness such as heart disease, lung disease, liver or kidney problems
-
People with weakened immune systems or certain medical conditions
-
Adults 65 and older with chronic health issues may be eligible for a second dose if it’s been more than a year since their first
Where to Get Vaccinated
People can get the vaccine through their primary care provider or by booking an appointment at TBDHU’s routine immunization clinic in Thunder Bay. Visit TBDHU.com/vaxclinics to make an appointment.
Currently, pharmacies are not offering this vaccine.
IPD Cases on the Rise
TBDHU has been tracking IPD cases closely. While numbers were lower during the COVID-19 pandemic, they have been steadily increasing:
-
2023: 63 cases
-
2024: 77 cases
-
2025 (so far): 95 cases
Although young children are also at risk, TBDHU reports no increase in IPD cases in infants or toddlers. However, parents are still urged to make sure their kids are up to date on all routine vaccines, which include protection against pneumococcal disease.
Stay Protected
Vaccination remains the best way to protect yourself and others from invasive pneumococcal disease. To learn more, visit the TBDHU IPD Information Page.
