Federal Government Marks National Immunization Awareness Week With Measles Push as Coverage Gaps Persist

The federal Minister of Health used National Immunization Awareness Week to call on provinces, territories, and health authorities to redouble efforts to close stubborn vaccine coverage gaps, with measles featuring as the most pressing immediate concern at a moment when North America and Europe have seen renewed measles activity for the first time in over two decades. The annual public-health observance, which has traditionally focused on broad messaging about vaccine safety and availability, has taken on additional weight this year as outbreak risks have grown and as several Canadian provinces have reported coverage rates well below the threshold required for measles herd immunity.

What the federal statement said

The federal statement, issued at the start of the week, framed immunization as the foundation of preventive health care and called attention to the ways in which Canadian vaccination coverage has slipped over the past several years. The minister acknowledged that coverage levels in some communities remain well below the ninety-five per cent threshold required to prevent measles transmission, and pointed to public-health messaging, school-based programmes, and community-based outreach as the primary tools for closing the gap.

The statement specifically highlighted the work being done with provincial, territorial, and community partners on vaccine confidence, on access for under-vaccinated populations, and on surveillance systems that can detect and respond to emerging outbreak risks. Federal officials have been working with provincial chief medical officers of health on coordinated responses to recent measles activity in Canadian and American communities.

The statement made clear that the federal government does not have direct authority over provincial immunization programmes and that the path to higher coverage runs primarily through provincial and territorial action. The federal role, officials emphasised, is to support coordination, to provide funding for surveillance and outbreak response, and to ensure consistent national messaging on vaccine safety and effectiveness.

The current measles picture

Canada has seen elevated measles activity in 2026 relative to the past several years, with cases reported in multiple provinces and with several outbreaks linked to international travel. The Public Health Agency of Canada has been tracking the activity closely and has issued enhanced surveillance guidance to provincial health authorities. Most Canadian cases have been imported or have arisen from clusters with limited domestic transmission, although several provinces have reported community transmission events.

The pattern in Canada is consistent with elevated measles activity across North America and Europe. The United States Centers for Disease Control and Prevention has reported significant case counts in multiple states, with some outbreaks reaching hundreds of confirmed cases. European authorities have similarly reported elevated activity in multiple countries. The World Health Organisation has flagged a global measles resurgence as a continuing public-health concern.

The factors driving the resurgence are well-documented. Vaccine coverage declined in many jurisdictions during the pandemic period, with school-based programmes disrupted and with routine well-baby visits postponed in many regions. Vaccine confidence eroded in some communities. Travel to and from regions with active outbreaks resumed at pre-pandemic levels.

Coverage by jurisdiction

Provincial coverage data show a mixed picture. Several provinces have maintained measles coverage above the ninety-five per cent threshold considered necessary for herd immunity. Other provinces, particularly those with significant under-vaccinated communities or with more disrupted school-based programmes during the pandemic, have reported coverage levels in the eighty to ninety per cent range, well below the threshold.

Within provinces, coverage varies further by community, region, and population. Some Indigenous communities have maintained strong coverage rates, while others have faced barriers including geographic isolation, limited primary-care access, and historical mistrust of federal health systems. Some immigrant communities have lower coverage in part because of differences in vaccination schedules between countries of origin and Canada. Some religious communities have lower coverage as a matter of long-standing practice.

Provincial chief medical officers of health have been emphasising that catch-up vaccination is the most important short-term tool. Children, adolescents, and adults who missed scheduled vaccinations during the pandemic period are being encouraged to seek catch-up doses through their family physician, primary-care nurse practitioner, public-health clinic, or pharmacist where pharmacists are authorised to administer vaccines.

The role of pharmacists

The expanded role of pharmacists in administering vaccines is one of the most significant changes in Canadian immunization delivery over the past decade. Most provinces now allow pharmacists to administer routine adult vaccinations, including measles, mumps, and rubella vaccine. Several provinces have extended pharmacist authority to paediatric vaccination as well.

The federal Canada Health Act amendments that took effect April 1 reinforce this trend by requiring provincial and territorial health plans to cover pharmacist-administered services that are equivalent to physician-delivered services. The change is expected to support continued expansion of pharmacy-based vaccination delivery across the country.

The Canadian Pharmacists Association said in a statement that pharmacy delivery has been a significant contributor to vaccine accessibility, particularly for adults seeking catch-up vaccination and for parents seeking convenient vaccination for school-age children outside of traditional clinic hours.

Indigenous health and immunization

For Indigenous communities, immunization presents both significant successes and significant challenges. Indigenous Services Canada has worked with First Nations, Inuit, and Metis communities on vaccination programmes that have achieved strong coverage in many regions, including during the pandemic period.

Several Inuit communities, including in Nunavik and Nunavut, have invested significantly in vaccination programmes and have achieved high coverage rates. Several First Nations communities have similarly invested in community-based vaccination delivery and have achieved coverage levels at or above provincial averages.

Other communities have faced more significant challenges. Geographic isolation, limited primary-care infrastructure, and the legacy of mistrust between Indigenous communities and federal health authorities all contribute to access barriers. The Carney government has committed to ongoing investment in Indigenous health infrastructure, including primary-care expansion and community-based public-health programmes.

Vaccine confidence and misinformation

The federal statement and provincial chief medical officers of health have all emphasised that vaccine confidence is a continuing concern. Misinformation about vaccine safety, particularly on social media platforms, has contributed to declining confidence in some communities. The federal government has invested in counter-messaging programmes and in support for evidence-based public-health communication.

The Canadian Medical Association, the College of Family Physicians of Canada, and the Society of Obstetricians and Gynaecologists of Canada have all emphasised that primary-care providers play a critical role in vaccine confidence. Patients trust their family physicians and nurse practitioners to provide accurate information about vaccine safety and effectiveness, and that trust is one of the most powerful tools for supporting vaccination uptake.

What it means for parents and patients

For parents of school-age children, the federal and provincial messaging is direct: ensure that your child's vaccinations are up to date, particularly with respect to measles, mumps, and rubella. Catch-up doses are available through family physicians, nurse practitioners, public-health clinics, and pharmacists in most provinces.

For adults who may have missed vaccinations during the pandemic period, the same message applies. Adults born after 1970 are generally recommended to have received two doses of measles vaccine, and those who are uncertain about their vaccination history are encouraged to consult their primary-care provider.

For people travelling internationally, particularly to regions with active measles outbreaks, vaccination is particularly important. Travel medicine clinics across Canada provide pre-travel consultations and vaccinations, and several provinces have expanded primary-care provider authority to provide travel medicine services.

What's next

The federal Minister of Health is expected to convene a meeting of provincial and territorial health ministers in the coming weeks to discuss immunization coverage and outbreak preparedness. The meeting is expected to address coordination of measles surveillance, response capacity, and public-health communication.

Provincial chief medical officers of health are expected to continue working through the spring and summer on coverage initiatives. Several provinces have launched new public-health campaigns aimed at supporting vaccine confidence and at promoting catch-up vaccination.

For Canadians, the practical message of immunization week is one of routine attention to a foundational public-health practice. Measles is one of the most contagious diseases in the world, and the only effective protection against it is vaccination. Whether the country can maintain coverage levels sufficient to prevent significant domestic outbreaks depends on millions of individual decisions, and on the public-health infrastructure that supports those decisions.
