A super appears on a pink background: COVID-19 vaccine questions
Cut to a new super on a white background with a pink border: What common side effects might children experience after being vaccinated?
Cut to a doctor in an office, then a super appears:
- Dr. Laura Sauvé
- Pediatric infectious disease specialist
- BC Children’s Hospital
The doctor answers the question.
Dr. Laura Sauvé: Some children will have no reaction to their COVID-19 vaccine, while others may have some short-term side effects.
These side effects are usually mild and clear up on their own within hours or days.
Side effects experienced by children in the clinical trials were similar to those for youth 12 and older. Common side effects can include redness and soreness and swelling at the injection site, and your child may also feel chills, mild fever, headache, and joint and muscle aches in the first day or two after being vaccinated.
As with adults, your child will be asked to wait onsite for about 15 minutes after vaccination to watch for allergic reactions. Severe allergic reactions are very rare. They usually occur within minutes after a person receives the vaccine, and they are treatable.

A super appears on a pink background: COVID-19 vaccine questions
A person seated in a living room speaks directly to the camera to ask a question: Can the COVID-19 vaccines affect fertility?
Cut to a doctor in an exam room, then a super appears:
- Dr. Darine El-Chaâr
- Maternal Fetal Medicine Specialist
- The Ottawa Hospital
The doctor responds to the person’s question.
Dr. Darine El-Chaâr: Multiple independent studies have shown that there is no evidence that COVID-19 vaccines cause fertility issues for anyone.
If you are pregnant, even early on, you are at a higher risk of severe illness from COVID-19. Evidence shows that mRNA COVID-19 vaccines are safe and recommended if you’re pregnant or breastfeeding.

A super appears on a pink background: COVID-19 vaccine questions
A person speaks directly to the camera: Are there any ingredients in the COVID-19 vaccines that I should be concerned about?
Cut to a doctor in an examination room, then a super appears:
- Dr. Ayesha Raza
- Family Physician, Women’s Health Specialist
- Centre Francophone de Toronto
The doctor responds to the question.
Dr. Ayesha Raza: Research and testing have shown the ingredients in the COVID-19 vaccines to be safe. They leave the body shortly after vaccination, like with all vaccines.
And as with all vaccines, COVID-19 vaccines teach the body’s immune system to recognize and attack the virus that causes COVID-19 and helps to protect you if you’re exposed to the virus in the future.
There are small amounts of ingredients in the vaccines and each one has a specific purpose to make the vaccine work. The ingredient list for each vaccine is available online.

The doctor responds to the person's question.
Dr. Upton D. Allen: The COVID-19 vaccines were rigorously tested during their development and carefully reviewed by Health Canada. After people have received the vaccines, real-world effectiveness and safety are monitored. Any safety concerns are expected to be very rare.
