Alberta Health Launches Review After Improper Pneumococcal Vaccine Administration

In a significant health alert, Alberta Health is conducting a thorough review of data from nearly 75,000 doses of pneumococcal vaccines following an internal investigation that uncovered improper administration intervals among a number of patients. This critical oversight means many adults and children may require reimmunization to ensure they are adequately protected against potentially serious pneumococcal diseases.

The issue stemmed from a combination of two different vaccines: Pneumo-P and Pneu-C20. Health authorities indicated that the recommended vaccination policy states there should be a minimum of one year between the last dose of Pneumo-P and the subsequent dose of Pneu-C20. However, the review revealed that some patients received their vaccinations too close together, which may diminish the effectiveness of the latter shot.

In response, Alberta Health has updated its vaccination policies and reminded pharmacists through a recent memo from Alberta Blue Cross about the importance of adhering to these timelines. The memo emphasizes that failure to respect the minimum intervals could lead to less effective immunization with Pneu-C20, necessitating reimmunization.

Looking at the numbers, nearly 28,000 doses of Pneumo-P were administered in 2023 alone, while the figures further indicate that from July to November 2024, almost 47,000 doses of Pneu-C20 were given out. Although Alberta Health asserts that there are no immediate adverse effects reported from receiving the vaccines too close together, they are currently working with immunization providers to assess how many patients have been impacted. As the analysis continues, the exact number of affected individuals remains undetermined.

Once this data is validated, the pharmacists will be tasked with reaching out to the affected patients to ensure they receive the necessary follow-up care. The Alberta College of Pharmacy has also been informed and is prepared to contact individual pharmacists as required to facilitate this process.

The Pneu-C20 vaccine is recommended for anyone aged two months and older who is at heightened risk for severe infections, including those with pre-existing health conditions such as heart, lung, kidney, or liver issues, those suffering from diabetes, individuals with compromised immune systems, and residents of care homes.

Pneumococcal vaccines are crucial in preventing severe infections such as pneumonia, meningitis, bacteremia, and sinusitis, all of which can lead to grave health complications. Pneumococcal disease is primarily transmitted through respiratory droplets from coughing, sneezing, and sharing food or toys—a significant concern for young children and older adults, who are particularly vulnerable to severe outcomes.

Statistics from Health Canada highlight the urgency of vaccination, revealing an eight percent fatality rate for children suffering from pneumococcal meningitis, which rises to 22 percent in adults. Survivors often endure permanent neurological damage, underscoring the critical need for effective prevention strategies, including proper vaccination protocols.

Stay informed and proactive in your health matters—ensure that you are up to date with any vaccination schedules and consult your healthcare provider if you suspect you may have been affected by this issue.
