Influenza, or “the flu,” is a contagious respiratory infection caused by different influenza viruses. The specific virus strains can change from year to year.
Flu symptoms can range from mild to severe and often include fever, cough, sore throat, muscle aches, and fatigue. While most people recover in about a week, the flu can sometimes lead to serious complications. These may include pneumonia, emergency room visits or hospitalisation, especially for older adults, young children, and people living with lung disease or chronic conditions.
Should I get a Flu Vaccine?
The flu vaccine is your best protection against the flu and its complications.
It helps by:
- Reducing your chances of getting sick
- Preventing serious flu-related illness or hospitalisation
- Protecting people around you from getting infected and sick – especially those at higher risk
In Canada, the flu vaccine is free and available to everyone 6 months and older. Pregnant individuals and people with chronic health conditions are especially encouraged to get vaccinated.
For adults 65 and older, a high-dose flu vaccine may be recommended, as it provides stronger protection for ageing immune systems. Speak to your healthcare provider or pharmacist to learn more.
When and Where to Get Your Flu Shot
Flu vaccines are updated every year to match the most common circulating strains. The best time to get vaccinated is in the fall, before flu season peaks.
It takes about two weeks after your shot for your body to build full protection.
Flu shots are available at local pharmacies, community flu clinics, and doctors’ offices across Canada.

You can also safely receive your flu shot at the same time as other vaccines, including COVID-19 or RSV vaccines
Vaccine Safety
The flu vaccine is safe and effective.
You cannot get the flu from the vaccine. Side effects, if any, are mild, such as a sore arm or brief fatigue. These symptoms go away within a few days.
Severe reactions are very rare, and vaccines in Canada are carefully monitored for safety.
Protect Your Lungs and Community
Getting your flu shot helps you stay healthy and protects those around you.
If you have asthma, COPD, or another lung condition, vaccination is one of the most effective ways to prevent serious respiratory illness this season.
