Ottawa – The Public Health Agency of Canada (PHAC) and its partners are focused on keeping people and animals in Canada safe and ensuring Canada is ready for any potential health threats. This includes taking proactive measures to protect the health of people in Canada by authorizing and securing the supply of a human vaccine against avian influenza as part of our readiness and potential use, as needed, based on risk conditions. Leveraging an existing agreement, PHAC has secured an initial supply of 500,000 doses of GSK’s human vaccine against avian influenza – ArepanrixTM H5N1 A/American wigeon clade 2.3.4.4b. This vaccine will be used as part of Canada’s contingency planning to protect people who may be at increased risk of being exposed to the virus through animals infected with avian influenza.
While the current risk to the public remains low, individuals with higher-level exposure to infected animals are at increased risk and should take appropriate precautions. Canada reported its first domestically acquired human case of avian influenza A(H5N1) on November 9, 2024, and continued vigilance will help prevent additional human cases. To date, there has been no evidence of sustained person-to-person spread of the virus in any of the cases identified globally. However, avian influenza has the potential to cause serious illness in people.
PHAC will provide vaccines to provinces and territories based on an equitable and risk-based approach, with 60% of available doses going to provinces and territories and 40% kept in a federal stockpile for national preparedness. Provinces and territories will make decisions on the potential use and administration of their respective vaccination programs in the context of local risk conditions, with PHAC supporting program monitoring and evaluation to adjust national efforts as needed.
