COVID-19 Vaccines

Information on the COVID-19 vaccine is evolving and current evidence is limited. Ensure to follow local public health measures. In order to make data available for Canadians, people living in the United States, and the rest of the world, we included information from the Public Health Agency of Canada, Centers for Disease Control and Prevention, and the World Health Organization.

Note: On May 5, 2021, Canada authorized the use of the Pfizer-BioNTech COVID-19 vaccine in children aged 12 and older. The Pfizer-BioNTech COVID-19 vaccine is not recommended for individuals who are allergic to ingredients in the vaccine, have had severe allergic reactions to a previous dose of this vaccine, or have symptoms due to COVID-19. Health Canada and the Public Health Agency of Canada aim to closely monitor the safety of the vaccine in children. 

Note: On May 12, 2021, the United States authorized the use of the Pfizer-BioNTech COVID-19 vaccine for children 12-15 years of age. The CDC recommends COVID-19 vaccination for individuals 12 years of age and older.

    • AstraZeneca COVID-19 vaccine for individuals 18 years of age and older
    • Janssen COVID-19 vaccine for individuals 18 years of age and older
  • Individuals who have received their first dose of the AstraZeneca vaccine are able to receive either the AstraZeneca vaccine or a mRNA vaccine (Pfizer or Moderna) for their second dose
  • According to current clinical trials, no serious safety concerns related to the vaccines have been identified, however studies are ongoing
  • COVID-19 vaccines are currently prioritized to individuals according to the National Advisory Committee on Immunization (NACI) Guidance on the Prioritization of Initial Doses of COVID-19 Vaccine(s)
  • NACI currently recommends that COVID-19 vaccines should not be offered to individuals who are not in the authorized age group
  • Regardless of vaccination with COVID-19 vaccine, all individuals should continue to practice recommended public health measures (e.g., good handwashing and physical distancing)

Centers for Disease Control and Prevention (CDC)
  • Vaccines that have been authorized and recommended to prevent COVID-19 are:
    • ​​​​Pfizer-BioNTech COVID-19 vaccine
    • Moderna’s COVID-19 vaccine
    • Johnson & Johnson’s Janssen COVID-19 Vaccine
  • According to the Advisory Committee on Immunization Practices (ACIP), the initial phase of the COVID-19 vaccination program will include healthcare personnel and individuals in long-term care facilities. Subsequent phases of the COVID-19 vaccination program include Phase 1b (frontline essential workers and individuals 75 years of age and older) and Phase 1c (other essential workers, persons 65–74 years of age, and individuals 16–64 years of age with underlying medical conditions).
  • The CDC is currently conducting two studies on COVID-19 vaccines in children. The first study is researching children’s immune responses against COVID-19 vaccines, and it is studying the immune response in children previously infected with COVID-19 (1). The objective of the second study is to research children who are at high risk for severe COVID-19 outcomes (2).
