Every autumn, I start hearing the same question: "Should I get the flu shot this year?" The logical, evidence-based pharmacist in me says, “For most people, yes.” However, for healthy adults between the ages of 18-50, my stance is neutral.
Now, it is important to remember that influenza is not simply a bad cold. Every year it causes significant illness, hospitalizations, missed workdays, and serious complications, particularly for young children, older adults, pregnant women, and people with chronic medical conditions. The Public Health Agency of Canada continues to recommend annual influenza vaccination for nearly everyone over six months of age.
The flu shot has overwhelming data in its favour for preventing significant illness and death in children, older adults, and immunocompromised individuals, but for healthy adults without chronic illness, I’m not pushing the flu vaccine. Some years, the flu vaccines are not even particularly effective against prevalent strains, and I would much rather see people maintain and boost their immunity through sleep, diet, exercise, stress management, and select supplements.
Here’s a very basic breakdown of your two main flu shot options this fall:
Option #1: The Traditional Flu Shot
This is still the most common influenza vaccine.
The formulation changes every year to match the influenza strains that experts believe are most likely to circulate during the upcoming season. Annual vaccination is recommended because those strains change over time.
The traditional flu shot remains a good choice for:
- Children
- Older adults
- Immunocompromised individuals
- Those with chronic illnesses
Option #2: The Nasal Spray Vaccine (e.g. FluMist)
Many people are surprised to learn that a needle-free flu vaccine exists.
FluMist is administered as a gentle nasal spray and is approved in Canada for certain individuals aged 2 to 59 years. It provides an alternative for people who dislike needles or have children who become anxious around injections.
Instead of being injected into the arm, the vaccine is sprayed into the nose where influenza viruses first enter the body.
However, it isn’t appropriate for everyone. Certain medical conditions and circumstances may affect eligibility, so it’s important to speak with your pharmacist or healthcare provider before choosing this option.
What About Natural Ways to Support Immunity?
As a “natural”-leaning pharmacist, I view healthy lifestyle habits and appropriate vaccination as foundational teammates, not competitors! They each have their suitable roles depending on the individual.
A strong lifestyle foundation for immunity includes:
- Quality Sleep (7-9 hours per night)
- Regular Exercise (but not overtraining!)
- Stress Management
- Adequate Protein Intake (0.7g+ per pound of bodyweight daily)
- Good Nutrition (limit processed foods!)
- Vitamin D3 Supplementation (when appropriate- get your levels checked!)
- Maintaining a healthy gut microbiome
These habits help support immune function year-round.
What they do not do is simply replace vaccination for influenza.
The strongest protection comes from combining healthy habits with evidence-based prevention strategies where appropriate.
My Pharmacist Perspective
Healthcare shouldn’t be about fear.
It’s about making informed decisions.
Whether you choose lifestyle interventions, the traditional flu shot, a needle-free option like FluMist, or a combination, understanding your choices allows you to make the decision that’s right for you and your family.
If you’re unsure which vaccine is most appropriate, speak with your pharmacist. We can help review your age, health conditions, medications, and preferences to determine the best option.
The goal isn’t simply avoiding illness this flu season.
The goal is staying healthy enough to keep doing the things you love.
