Getting Vaccinated and Staying Up to Date

When to get your next dose

Eligibility for booster doses is based on the interval since your last dose. Once you have completed your primary series, individuals aged five and older can receive a booster dose at a recommended interval of six months (minimum three), since your last dose. Details on vaccine eligibility and doses by group.

If it has been six months since your last dose, it's time to get vaccinated again. Find out where you can get vaccinated.

  • Recommended COVID-19 vaccine products

    Every effort should be made to get vaccinated with an mRNA vaccine for the primary series and any booster dose(s). mRNA are highly safe and effective COVID-19 vaccines and are widely available across Niagara.

    Individuals 18 years of age and older who are interested in accessing a dose of Janssen and Novavax should contact the Niagara Region Public Health COVID-19 Info-Line at 905-688-8248, press 7, then 2, to be added to a wait list, after first being assessed for eligibility.

  • Getting other vaccines at the same time

    With COVID-19 still circulating in the community, everyone is encouraged to get up to date with all vaccines, including the COVID-19 bivalent vaccine if eligible, and the flu shot once available.

    COVID-19 vaccines may be given at the same time as, or any time before or after, other vaccines, for all age groups.

  • People who come into close contact with those who are immunocompromised

    To protect those who are immunocompromised, it's strongly recommended that all people that come into close contact (for example, health workers and other support staff, family, friends, caregivers) with these individuals stay up to date with their COVID-19 vaccines. They should also continue to follow the layers of protection from COVID-19.

  • People who are pregnant or breastfeeding

    The National Advisory Committee on Immunization continues to strongly recommend that individuals who are pregnant or breastfeeding get vaccinated and stay up to date. COVID-19 vaccinations can be given offered at any stage of pregnancy (in any trimester).

    Getting vaccinated is your choice. We want you to feel confident in your decision. It's really important to make sure you understand as much as you can about COVID-19 and the vaccine so you can make an informed choice. Learn more about COVID-19 vaccines in pregnancy.

  • People who received vaccines not authorized by Health Canada

    Primary series

    People who received only one or two doses of a non-Health Canada authorized COVID-19 vaccine may receive one additional dose in Ontario at least 28 days after the previous dose to complete the primary series.

    People who received one Health Canada authorized vaccine and one non-Health Canada authorized vaccine (in either order) need no additional doses to complete the primary series.

    People who received three doses (any combination of Health Canada authorized, and non-Health Canada authorized) need no additional doses to complete the primary series.

    Additional doses / boosters

    Following any additional doses needed to complete the primary series, these individuals should follow the recommendations based on age for their booster dose(s) (if eligible).

    More information

    If you are staying in Canada to live, work or study and have been vaccinated with vaccines not authorized by Health Canada, refer to the Public Health Agency of Canada's COVID-19 immunization recommendations.

    If you don't have a vaccine certificate (record of vaccination):

    • If you received a previous dose (s) of a COVID-19 vaccine but don't have a vaccine certificate (record of vaccination), see if you can obtain one
    • If the COVID-19 vaccine product you received remains unknown, a new vaccine series may need to be started with a Health Canada authorized COVID-19 vaccine
  • People who have had COVID-19

    You should still get your vaccine even if you had a previous COVID-19 infection. Getting vaccinated can strengthen and provide longer lasting protection against COVID-19. Compared to previous variants, Omicron has a higher reinfection rate for people who had a previous COVID-19 infection.

    A previous COVID-19 infection is defined as when an individual has

    • Tested positive for COVID, either by rapid antigen or PCR test, or
    • Had COVID-19 symptoms AND lived with a confirmed case

    If you had a COVID-19 infection before you started or completed your primary series

    Recommended to receive the vaccine eight weeks before the next dose in your primary series.

    If you had a COVID-19 infection after completing your primary series

    Recommended to receive the vaccine at least six months (minimum three) after your infection. A six month interval may provide better immune response, regardless of the product given.
