Frequently Asked Questions:

Based on the Ontario Expanded Eligibility for third/booster dose of COVID-19 vaccine, the province will begin offering booster doses to the following vulnerable populations if at least three months have passed since their last dose:

  • People who are immunocompromised
  • Individuals aged 18 and over (born in 2003 or earlier);
  • Health care workers and designated essential caregivers in congregate settings (including long-term care home and retirement home staff and designated caregivers);
  • Individuals who received a complete series of a viral vector vaccine (two doses of the AstraZeneca vaccine or one dose of the Janssen vaccine); and
  • First Nation, Inuit and Métis adults and their non-Indigenous household members.

Booster doses are being offered to these groups based on evidence of gradual waning immunity six months after receiving their second dose and a higher risk of severe illness from COVID-19.

A third dose can be given at a minimum of two months (56 days) after the second dose for:

  • People receiving dialysis (hemodialysis or peritoneal dialysis)
  • Transplant recipients of a solid-organ transplant or hematopoietic stem cell transplant (within two years of transplantation or taking immunosuppression therapy)
  • People undergoing active treatment* for solid tumors and hematologic cancers
  • Recipients of chimeric antigen receptor (CAR)-T-cell
  • People with moderate or severe primary immunodeficiency (e.g. DiGeorge syndrome, Wiskott-Aldrich syndrome)
  • People undergoing active treatment** with the following categories of immunosuppressive therapies: anti-B cell therapies (monoclonal antibodies targeting CD19, CD20 and CD22), high-dose systemic corticosteroids (refer to the Immunization of Immunocompromised Persons – Canadian Immunization Guide for suggested definition of high dose steroids), alkylating agents, antimetabolites, tumour-necrosis factor (TNF) inhibitors, and other biologic agents that are significantly immunosuppressive (see Table 1 of the COVID-19 Vaccine Recommendations for Third Doses***)

All eligible individuals will be able to book their booster dose appointment through the COVID-19 vaccination portal or by calling the Provincial Vaccine Contact Centre, directly through public health units that use their own booking systems, through Indigenous-led vaccination clinics, select pharmacies, and primary care settings. Hospital-based health care workers are encouraged to reach out to their hospital employer to get vaccinated directly through their hospital’s vaccination program.

For vaccine eligibility requirements specific to Ontario, click here.

The recommended interval for boosters is ≥6 months (168 days) after the completion of the primary series.

If you are currently not eligible under the published criteria, you may fill out the form and provide your date of birth and date of last dose, we will contact you once you are considered eligible.

Yes, we are preparing to provide a safe space to administer Pfizer Vaccines for children 5 to 11 yos for a limited time. We ask that all clients eligible register their dependents on our registration page. We will reach out to clients eligible for Paediatric Pfizer COVID-19 vaccine on a first come, first served basis. Appointments will only be offered to clients who meet Provincial or City of Toronto eligibility criteria.

Children given the Pfizer-BioNTech COVID-19 vaccines had side effects similar to those experienced by people age 16 and older. The most commonly reported side effects include:

  • Pain where the shot was given
  • Fatigue
  • Headache
  • Chills
  • Muscle pain
  • Fever
  • Joint pain
  • Swollen lymph nodes
  • Nausea
  • Decreased appetite

Similar to adults, children have side effects within 2 days after vaccination that typically last 1 to 3 days. More children reported these side effects, except for injection site pain, after the second dose of the vaccine. However, some people have no side effects.

After your child is given a COVID-19 vaccine, he or she will be monitored for 15 to 30 minutes to see if he or she has an allergic reaction that requires treatment.

It isn’t recommended that you give your child an over-the-counter pain reliever before vaccination to prevent side effects. It’s OK to give this kind of medication after your child gets a COVID-19 vaccine.

It is important to note that children 5-11 years old had short-term side effects less often than older adolescents and adults.

The Pfizer-BioNTech COVID-19 vaccine for children ages 5 through 11 contains a lower dose (10 micrograms) than the vaccine used for older children and adults (30 micrograms). Smaller needles are being used to deliver the vaccine to children ages 5 through 11.


The Pfizer-BioNTech COVID-19 vaccine for children ages 5 through 11 also contains a different buffer than the vaccine used for older children and adults. This different buffer, which is used in other FDA-approved vaccines, will help keep the vaccine stable in refrigerated temperatures for longer.

The ingredients and dosing of the Pfizer-BioNTech COVID-19 vaccine are the same for children ages 12 through 15 and people age 16 and older.

How far apart should children ages 5-11 receive their first and second dose?

This vaccine is not yet available to children younger than age 5. Clinical trials involving younger children are in progress.

The vaccine also shouldn’t be given to a child with a known history of a severe allergic reaction to any of its ingredients. If this is the case, your child might be able to get another COVID-19 vaccine in the future.

In the U.S., there has been an increase in reported cases of myocarditis and pericarditis after mRNA COVID-19 vaccination, particularly in males ages 12 through 17. Myocarditis is the inflammation of the heart muscle, while pericarditis is the inflammation of the lining outside the heart. These reports are rare. One study suggests that the risk of myocarditis in the week after being fully vaccinated with the Pfizer-BioNTech vaccine is about 54 cases per million doses given to males ages 12 to 17.

Of the cases reported, the problem happened more often after the second dose of the COVID-19 vaccine and typically within several days after COVID-19 vaccination. Most of the people who received care quickly felt better after receiving medicine and resting. Symptoms to watch for include:

  • Chest pain
  • Shortness of breath
  • Feelings of having a fast-beating, fluttering or pounding heart

If you or your child has any of these symptoms within a week of getting a COVID-19 vaccine, seek medical care.

COVID-19 infection is much more likely to cause myocarditis in children, especially children who develop multisystem inflammatory syndrome , than the vaccine.

  • Presently in Ontario, Pfizer and Moderna vaccines are being offered.
  • Ontario will continue using the Pfizer-BioNTech vaccine for youth ages 5-17 (including those turning 12 in 2021)
  • A booster dose is not approved by Health Canada for 5 to 17 year olds.
  • It is recommended that 18-24 year olds receive the Pfizer vaccine based on the current available data from Ontario’s adverse events following immunization (AEFI) surveillance system. Individuals 18-24 years old can still receive the Moderna vaccine with informed consent.
  • Anyone who got a complete vaccination series of a viral vector vaccine (e.g., two doses of AstraZeneca vaccine or one dose of Janssen) are recommended to get a booster of either mRNA COVID-19 vaccine (Pfizer-BioNTech Comirnaty or Moderna Spikevax)
  • If you are are getting a booster:
  • For the Pfizer-BioNTech Comirnaty mRNA vaccine, a full dose (30 mcg) is recommended.
  • For the Moderna Spikevax mRNA vaccine, a full dose (100 mcg) is recommended for adults living in long-term care homes or other congregate living settings that provide care for seniors 70 years of age and older. A half dose (50 mcg) is recommended for other adults.

Vaccine effectiveness against severe COVID-19 outcomes with all vaccine types (including viral vector) remains high, but it is currently unclear to what extent the duration of protection may vary by vaccine product.

Our Medical Advisory Services team highlights the efficacy of Canada’s approved vaccines below.

After ten months of the COVID-19 vaccines being released, scientific evidence still suggests it is the best line of defense against the virus. While no vaccine is 100% effective, getting vaccinated provides the highest level of safety for ourselves and our community members. Below is a chart that highlights the effectiveness of the vaccines against the delta variant as of August 27th.

Important note: As for Moderna, the efficacy rate reflected on the chart is only based on one dose as ongoing research is being conducted for the efficacy of two doses.

The COVID-19 vaccine is free for everyone in Ontario.

Residents without OHIP cards who meet the current vaccine eligibility criteria for their first or second dose may get vaccinated at any clinic. A health card is not needed; however, individuals must bring an acceptable form of identification which may include government-issued ID such as a driver’s license or passport, a piece of mail with your name on it, a pay stub, or a student card.

Consult with your health care provider before getting vaccinated, if you:

  • are on medications that weaken your immune system – you may want to time your vaccination with your medications
  • had an allergic reaction within four hours after receiving your first COVID-19 vaccine dose
  • have severe allergies to any of the vaccine ingredients

Your health care provider will review the benefits and risks for your unique situation.

Please be aware that for those 5-11 years of age, the COVID-19 vaccine cannot be given within 14 days of another vaccine ie. flu shot.

Should there be changes to your eligibility, please notify our Vaccine team at

If you have any questions, or require additional guidance, please consult your family physician—at Medcan or elsewhere.
