Are vaccines safe?

Yes. Vaccines used in Quebec are subject to rigorous safety controls. Side effects are generally mild and temporary, such as a slight fever or soreness at the injection site.

At what age should my child receive their vaccines?

The vaccination schedule begins at 2 months of age and includes boosters at specific ages to ensure optimal protection.

Can my child be vaccinated if they have a cold or are taking antibiotics?

Yes. A mild cold or taking antibiotics is generally not a contraindication to vaccination.

Do vaccines weaken the immune system?

No. On the contrary, vaccines strengthen the immune system by teaching it to recognize and fight specific pathogens.

Which vaccines are recommended for adults?

Adults should receive certain essential vaccines throughout their lives, such as:

flu vaccine (annually),
tetanus, diphtheria, and pertussis vaccine (booster every 10 years),
shingles vaccine (from age 50),
and, depending on the situation, vaccines against hepatitis A and B, pneumococcal disease, or human papillomavirus (HPV).

Travel Vaccinations:

Additional vaccines may be required depending on your destination (e.g., yellow fever, typhoid, Japanese encephalitis, rabies, etc.). It is recommended to visit a travel health clinic several weeks before your departure to receive appropriate advice and vaccinations.

Which vaccines are required for international travel?

The vaccines required or recommended depend on your destination, the length of your stay, local conditions, and your health status.

Frequently recommended vaccines for travellers:

Yellow fever (required for certain countries in Africa and South America)
Hepatitis A and B
Typhoid
Rabies (for extended travel or rural areas)
Japanese encephalitis (Southeast Asia and rural areas)
Meningitis (certain regions of Africa or for the pilgrimage to Mecca)

When should you consult?
Ideally, book an appointment at a travel health clinic 4 to 6 weeks before your departure. This allows time to receive the necessary doses and ensure proper protection.

How can I get proof of vaccination?

Proof of vaccination is available through the vaccination registry of Quebec. You can also obtain it from your CLSC or your doctor.

What are the possible side effects of vaccines?

Vaccines are generally well tolerated. The vast majority of side effects are mild and temporary. The most common include:

pain, redness, or swelling at the injection site
a slight fever
fatigue or a general feeling of discomfort
sometimes headaches or loss of appetite (especially in young children).

These reactions are normal: they indicate that the immune system is responding to the vaccine. They usually go away within 24 to 72 hours.

Less common side effects:
In rare cases, more significant reactions can occur, such as a high fever or more noticeable swelling of the arm or leg. These effects remain temporary and are easily treated.

Severe allergic reactions:
Severe allergic reactions (e.g., anaphylactic shock) are extremely rare—about 1 case per million doses—and healthcare professionals are trained to respond immediately if this occurs.

What should you do if you’re concerned?
If you notice a reaction that seems unusual or persistent after a vaccine, don’t hesitate to contact a healthcare professional.
