What is the optimal interval between the first and second dose for 2-dose COVID-19 vaccines for children?

The optimal interval between the first and second dose of an mRNA COVID-19 vaccine is eight weeks.

  • More data has become available that suggests that protection can be improved upon when the interval between the first and second doses are extended beyond the original manufacturer’s recommended interval (e.g., 21 days between first and second dose of a Pfizer-BioNTech COVID-19 vaccine). 
  • As per NACI, there is emerging safety data that suggest that a longer interval between dose one and two may reduce the risk of myocarditis/pericarditis after the second dose of an mRNA COVID-19 vaccine.
  • These intervals appear to provide optimal protection while simultaneously minimizing the time at risk of infection due to having protection from only one dose. 
  • Individuals may choose to speak with their primary care provider about what interval is best for them considering the local transmission of COVID-19 and the degree of individual risk of exposure. 
  • The authorized interval may still be used with informed parental consent.
  • Interruption of a vaccine series resulting in a greater interval between doses than recommended does not require re-starting the series.

  • Children were invited to share messages on clinic white boards after receiving their COVID-19 vaccine.  Please enjoy these snapshots of their creative messages and drawings.


What are the possible side effects of the COVID-19 vaccine for children?

Like any other vaccine or medication, there are potential side effects of the COVID-19 vaccine, although not everyone experiences them to the same degree. Individuals who experience side effects mostly reported that they are mild and resolve within the first two days after vaccination.

The most common side effects include:

  • pain at the injection site
  • tiredness
  • headache
  • muscle and joint pain
  • chills
  • mild fever

Side effects can be a sign that your child’s body is working to develop their immunity. 

With ongoing monitoring of the safety and effectiveness of the COVID-19 vaccines, serious side effects are extremely rare. Vaccination is still highly recommended as the benefits of vaccination outweigh the potential risks. Learn more at

Vaccine Safety

Vaccination is one of the most effective ways to prevent the spread and reduce the impact of infectious diseases, whether it is the seasonal influenza or childhood infections such as chickenpox. While many people infected with COVID-19 experience only mild illness, others may get a severe illness or even die or have long lasting effects. There is no way to know how COVID-19 will affect you, even if you are not at increased risk of severe complications.

Healthy Choices, Healthy Children: Why Vaccinations Are A Healthy Choice for A Strong Immune System! Myths and FACTS (MHLTC) 

Preparing Your Child

Needles can be scary for some children and their parents. The CARD system (Comfort, Ask, Relax, Distract) provides groups of strategies that can be used before and during vaccination to make the experience a more positive one for you and your child. 


AFTER the vaccination

Be positive and help your child feel good about the experience. Avoid focusing on the pain. Give praise to your child; consider such phrase as “You did a fantastic job”, or “Now you know you can do it!” 

Review any information your health care provider gives you about vaccines, especially information that describes any mild reactions that might happen. These reactions are normal and will go away very quickly.

Adverse Event Following Immunization (AEFI)

An adverse event following immunization (AEFI) is an unwanted or unexpected health effect that happens after someone receives a vaccine, which may or may not be caused by the vaccine. Monitoring AEFIs is an important part of all vaccine programs and contributes to the success of any immunization program. All clients receiving the COVID-19 vaccine are advised to contact their primary care provider or call the health unit if they are experiencing an AEFI. When a medical provider reports an AEFI, they complete a form and then send it to their local public health unit for investigation and assessment.

All AEFIs are thoroughly investigated by Public Health Nurses and signed off by the Medical Officer of Health. Most of these events were local reactions and were fully self-resolving. Learn more about AEFIs related to Ontario’s COVID-19 vaccine program here:
