Flu Season Guide for Seniors

Influenza is more than just a seasonal nuisance for older adults. For Canadians aged 65 and older, the flu poses a serious health threat, leading to the highest rates of hospitalizations and deaths each year. Recent data from the 2025–2026 flu season confirms that seniors continue to face the greatest risk of severe flu outcomes. Understanding why flu season matters more as we age and taking the right preventive steps can make a significant difference in staying healthy and protected.

Why Flu Season Is More Dangerous for Seniors

As people age, their immune systems weaken through a natural process called immunosenescence. This decline means that older adults:

• Experience more severe infections

• Take longer to recover

• Face higher chances of complications such as pneumonia, heart problems, or loss of independence

  
  

Seniors with chronic illnesses like diabetes, heart disease, or lung conditions are even more vulnerable. Influenza can worsen these conditions, increasing the risk of hospitalization or long-term health decline.

Get the Right Flu Vaccine Every Year

Annual flu vaccination remains the most effective way to reduce the risk of influenza and its complications. Health authorities recommend that all adults 65 and older receive a flu shot each year, ideally before flu activity peaks in the community.

Enhanced Vaccines for Seniors

Standard flu vaccines do not work as well in older adults. To improve protection, Canada’s National Advisory Committee on Immunization (NACI) advises seniors to get enhanced flu vaccines, which include:

• High-dose influenza vaccine: Contains a higher amount of antigen to stimulate a stronger immune response

• Adjuvanted influenza vaccine: Includes an ingredient that boosts the body’s immune reaction

  
  

These vaccines provide better protection against flu strains common in seniors and reduce the risk of severe illness.

Practice Good Hygiene to Reduce Exposure

Simple hygiene habits can lower the chance of catching or spreading the flu:

• Wash hands frequently with soap and water for at least 20 seconds

• Use alcohol-based hand sanitizer when soap is unavailable

• Avoid touching your face, especially eyes, nose, and mouth

• Cover coughs and sneezes with a tissue or your elbow

• Clean and disinfect frequently touched surfaces regularly

  
  

These steps help block the virus from entering the body or spreading to others.

Maintain a Healthy Lifestyle to Support Immunity

A strong immune system helps fight infections more effectively. Seniors can support their immunity by:

• Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins

• Staying hydrated by drinking plenty of water

• Getting regular physical activity suited to their ability

• Ensuring adequate sleep each night

• Managing stress through relaxation techniques or hobbies

  
  

These habits contribute to overall health and improve the body’s ability to respond to infections.

Avoid Crowded Places During Peak Flu Season

Flu viruses spread easily in crowded indoor spaces. Seniors should try to:

• Limit time spent in crowded public places, especially during peak flu months

• Use masks in high-risk settings or when flu activity is high

• Opt for outdoor gatherings or well-ventilated areas when socializing

  
  

Reducing exposure to large groups lowers the chance of catching the flu.

Know the Signs and When to Seek Medical Help

Early recognition of flu symptoms can lead to timely treatment and better outcomes. Common signs include:

• Fever or chills

• Cough

• Sore throat

• Muscle aches

• Fatigue

• Headache

  
  

Seniors should contact their healthcare provider promptly if they experience flu symptoms, especially if they have underlying health conditions. Antiviral medications may be prescribed to reduce the severity and duration of illness if started early.

Stay Up to Date on Other Vaccinations

Besides the flu vaccine, seniors should keep other vaccinations current to prevent complications:

• Pneumococcal vaccine to protect against pneumonia

• COVID-19 vaccine and boosters

• Shingles vaccine

  
  

These vaccines help reduce the risk of infections that can worsen flu outcomes.

Prepare Your Home and Support Network

Being prepared can ease the burden if illness strikes:

• Keep a supply of tissues, hand sanitizer, and disinfectants at home

• Stock up on easy-to-prepare nutritious foods and fluids

• Arrange for someone to assist with errands or care if needed

• Have a list of emergency contacts and healthcare providers handy

  
  

Preparation helps seniors recover comfortably and safely.

Taking these steps can help seniors face flu season with confidence and reduce the risk of serious illness. Getting the right vaccine, practicing good hygiene, maintaining a healthy lifestyle, and knowing when to seek care are key to staying protected. Seniors and their caregivers should work together to build a flu season plan that fits their needs.

Staying informed and proactive is the best way to protect health during flu season. Talk to your healthcare provider about the best flu vaccine for you and any other precautions to take this year.
