Walk-in vaccination clinic

Walk-in clinics are set up based on vaccine availability. Visit the websites of healthcare institutions to get details about the vaccination clinic nearest you.

If you have a contraindication to messenger RNA vaccines, or if you refuse these vaccines, visit the websites of healthcare institutions to find out how to get a COVID-19 recombinant protein vaccine with adjuvant (Novavax).

Any electronic or telephone communication offering COVID-19 vaccination for a fee is fraudulent. Moreover, you never have to provide your social insurance number (SIN) or credit card number to get vaccinated.

Goals of vaccination

The main goal of vaccinating against COVID-19 is to reduce hospitalizations and deaths associated with COVID-19 for those most at risk.

Number of vaccine doses

COVID-19 vaccination includes primary doses and booster doses. The number of recommended doses depends on the situation of the vaccinated person.

People aged 18 years and older

A primary vaccine is recommended (two doses at an interval of eight weeks or more).

For the fall 2022 vaccination, it is recommended to get one booster dose five months after the last dose.

Youth 6 months to 17 years

Parental consent

Young people aged 13 years and under need the consent of a parent or legal guardian to be vaccinated. People 14 years of age and older can give their own consent for COVID-19 vaccination.

Children from 6 months to 4 years

A primary vaccine is offered to children aged 6 months to 4 years (two doses at an interval of eight weeks or more).

Booster doses are not offered to children under the age of 5 years.

Children from 5 to 11 years

A primary vaccine is offered to children aged 5 to 11 years (two doses at an interval of eight weeks or more).

A booster dose is also offered to these children, five months after the last primary dose.

Youth from 12 to 17 years of age

A primary vaccine is recommended (two doses at an interval of eight weeks or more).

A booster dose is also offered to these youth, five months after the last primary dose.

Youth considered to be at high risk for complications

After the primary vaccine (two doses at an interval of eight weeks or more) a booster dose is recommended for youth aged 5 to 17 years who are considered to be at high risk for complications, presenting with conditions such as the following:

  • a cardiac, pulmonary, liver, kidney or blood disorder
  • diabetes
  • obesity
  • a medical condition that may affect the ability to expel respiratory secretions or that may cause a risk for aspiration
  • another condition identified by the attending physician.

It is recommended to get this dose five months after the last primary dose.

People who are immunocompromised or on dialysis

6 months to 4 years

A primary vaccine is recommended (three doses at an interval of four weeks or more).

Booster doses are not offered to children under the age of 5 years.

5 years and older

A primary vaccine is recommended (three doses at an interval of four weeks or more).

For the fall 2022 vaccination, it is recommended to get one booster dose three months after the last dose.

Since these people have a less robust immune response and are at a greater risk of developing more serious complications from the illness than healthy people, it is preferable to protect them more quickly.

People who have had COVID-19

People who have had COVID-19 may need fewer doses, but could get all the doses offered if they wish.

An interval of three months is recommended between a COVID-19 infection and a COVID-19 vaccine dose, while adhering to the interval required between vaccine doses.

People in residential care centres or living in group homes

Booster doses are recommended for people living in CHSLDs and RPAs, and other settings with a high proportion of elderly and vulnerable people, such as some intermediate and family-type resources, as well as some religious communities.

A booster dose is also recommended for youth 12 to 17 years of age living in a group home.

Pregnant women

It is recommended that pregnant women get vaccinated because they present a higher risk of complications from COVID-19 than women who are not pregnant.

Importance of booster doses

A booster dose allows the immune system to re-establish a sufficient level of antibodies to compensate for the drop that may occur after a few months.

Types of vaccines

COVID-19 messenger RNA vaccine

Québec experts recommend messenger RNA vaccines because they are more effective. These vaccines include:

  • The Pfizer vaccine, approved for people 5 years of age and older;
  • The Moderna vaccine, approved for people aged 6 months and older.

The Pfizer vaccine is recommended for people aged 5 to 29 because it may present a lower risk of pericarditis and myocarditis. The Moderna vaccine may be obtained on demand or offered to some young people with health problems that affect their immune system.

Pediatric vaccine formulations are used for children aged from 6 months to 11 years.

COVID-19 recombinant protein vaccines with adjuvant

These vaccines include Novavax and Medicago. They are approved for people 18 years of age and older in one of the following situations:

  • when messenger RNA vaccines are contraindicated
  • when a person refuses a messenger RNA vaccine.

A COVID-19 messenger RNA vaccine is recommended as a booster dose. However, people with a contraindication or who refuse messenger RNA vaccines may choose a recombinant protein vaccine with adjuvant as a booster dose.

The Medicago vaccine is not currently available in Québec.

COVID-19 viral vector-based vaccines

These include the AstraZeneca, Covishield and Janssen vaccines. They are not currently available in Québec.

How vaccines work

When a person is vaccinated against COVID-19, the body prepares its defence against the virus. A natural immune response is triggered that neutralizes the virus by producing antibodies and other defence cells.

The virus that causes COVID‑19 is composed of a strand of genetic material, RNA (ribonucleic acid), surrounded by an envelope. The surface of the virus contains proteins, including the S protein (spike protein) which gives it its crown shape, hence its name coronavirus. The S protein allows the virus to infect cells in the human body.

COVID-19 messenger RNA vaccines and viral vector-based vaccines block the S protein, preventing the virus from entering and infecting human cells.

The COVID-19 recombinant protein vaccines with adjuvant contains the S protein (spike protein) and uses it as an antigen. The addition of adjuvant facilitates activation of the immune system cells to prevent the virus from entering human cells and infecting them.

These vaccines do not protect against colds and respiratory infections caused by other viruses, such as influenza.

Vaccines cannot cause COVID‑19 because they do not contain the SARS‑CoV‑2 virus, responsible for the illness. However, a person who has been in contact with the virus in the days preceding or following vaccination could still develop COVID‑19. It is important to continue applying the recommended health measures.

Symptoms after vaccination

Vaccination may cause symptoms such as redness at the injection site. Other problems may arise by chance and are unrelated to vaccination, such as a cold or gastroenteritis.

Most reactions are mild and short-lived. Local reactions may occur up to 8 days after vaccination. Reactions are less common in children under 12 and people over 55 years of age. They are most common after the second dose. For further information, please consult the Vaccine information sheets for population This hyperlink will open in a new window..

Safety of the vaccines

The COVID‑19 vaccines approved by Health Canada are safe. They have been tested in quality studies on a large number of people and have gone through all the necessary steps prior to approval. They must meet the same quality and safety standards as any other vaccine used in Canada. Experts closely monitor any adverse events that might occur after vaccination and take measures to ensure that these vaccines are safe and effective.
