A new Lakeridge flu shot message is asking Durham residents to think about heart health as well as respiratory illness when discussing seasonal vaccination with a health care provider.
In an October 26 article, Lakeridge Health explains that infections such as influenza can trigger inflammation and place additional strain on the cardiovascular system. The hospital network says the concern is especially relevant to older adults and people with existing health conditions.
Potential benefit beyond avoiding influenza
Lakeridge says research suggests vaccination against respiratory infections may also offer cardiovascular protection, particularly for older people and those who already have heart disease.
The Public Health Agency of Canada’s published review of influenza vaccination evidence also describes a possible protective effect against cardiovascular events in higher-risk populations. That is a potential additional benefit, not a guarantee that a vaccinated person cannot experience a heart attack or stroke.
Individual advice remains important
The Lakeridge flu shot article encourages residents to ask a doctor, nurse practitioner or pharmacist which vaccines are appropriate for their age, health and vaccination history. It also discusses COVID-19, RSV and pneumococcal protection; those products do not all have the same eligibility rules or dosing schedule.
The local hospital network’s message is distinct from Durham Region’s earlier announcement about where residents can obtain fall vaccines. Its focus is the connection between serious respiratory infections and cardiovascular health, rather than a new clinic opening or a change to local appointment dates.
No new local cardiovascular case count or vaccine trial result is announced in the article. It is a fresh public-health message from Lakeridge Health drawing on existing evidence, not a claim that the hospital network has discovered a new treatment.
