COVID-19 Vaccines

Here is a preview of our most recent updates on the vaccine development:

Information on COVID-19 vaccines is evolving. Ensure to follow local public health measures. This webpage provides current information about COVID-19 vaccines for children. In order to make data available for Ontarians, other Canadians, people living in the United States, and the rest of the world, we have linked information from the Government of Ontario, Public Health Agency of Canada (PHAC), Centers for Disease Control and Prevention (CDC), and the World Health Organization (WHO).

All vaccines authorized by Health Canada, the U.S. Food and Drug Administration, and the WHO are validated to be safe and effective at protecting against COVID-19 infection.1 Vaccination also provides protection against severe COVID-19 disease. Getting vaccinated helps keep your community safe by reducing your risk of getting infected with COVID-19 and transmitting it to others. Although vaccine effectiveness against the Omicron variant is currently unknown and being studied, vaccination remains the best strategy to protect ourselves against COVID-19. 2 

Vaccines for children are safe and effective. While most children experience mild COVID-19 symptoms, some children (including those who have chronic illnesses) will experience more severe disease and may be hospitalized. 3 A few children with severe COVID-19 experience serious complications such as multisystem inflammatory syndrome in children (MIS-C), a critical condition in which vital organs become severely inflamed.4 Some children may have long-lasting symptoms, and in rare cases, COVID-19 can cause death. 3 It is important to vaccinate children to protect them from serious illness as well as to prevent transmission to family and friends. 

All vaccinated individuals should continue to practice recommended public health measures (e.g., handwashing, wearing masks, physical distancing). 

Supporting your Child getting Vaccinated

Vaccination can be stressful for children. Here are some resources to learn how to help your child have a comfortable experience receiving their COVID-19 vaccine: 

What to Expect After Vaccination

Your child will be monitored by a healthcare provider for 15 minutes following vaccination to watch for signs of an allergic reaction. Having an allergic reaction to the vaccine is rare, and the condition is treatable.3 

It typically takes two weeks for the COVID-19 vaccine to provide maximum protection.3,5 After vaccination, continue to follow public health guidelines. Maintain proper hand washing, physical distancing, and mask wearing.  

Possible side effects of the vaccine in children 6 

It is normal for your child to experience mild side effects following vaccination, which will go away on their own. These side effects indicate that the vaccine is working properly. Many children do not have any side effects.  

Common side effects in children include:  

  • Soreness, redness, or swelling at the site of injection 
  • Chills 
  • Fatigue 
  • Body aches 
  • Headache 
  • Mild fever 

While these side effects will go away on their own, non-aspirin medications such as Advil or Tylenol can be given to the child to relieve pain. CDC advises against taking these medications before vaccination.

Timing with Other Vaccines 

It is safe for adults and youth aged 12 to 17 years to receive other vaccines (e.g., the flu vaccine, routine immunizations) at the same time as receiving a COVID-19 vaccine.7
