COVID-19 Booster Doses

The bivalent COVID-19 vaccine is an updated version of the COVID-19 vaccine that targets the original COVID-19 virus and the Omicron variant. Bivalent vaccines are available as booster doses for eligible individuals in Ontario aged 5 years of age and older.

Individuals age 5 and older may receive a Pfizer bivalent vaccine product. The bivalent Moderna vaccine is approved for individuals 18 years and older. There is currently no approved booster vaccine for individuals less than 5 years of age.

Individuals who are at higher risk of severe COVID-19 illness, including individuals aged 65 and older, are recommended to get their next booster dose if it has been at least six months since their last dose or confirmed COVID-19 infection.

Individuals not at high-risk of severe COVID-19 illness should receive a booster dose if they have not had a booster dose since September 1, 2022 and have not had a COVID-19 infection in the last six months.

Appointments are strongly recommended and can be booked online (www.GetYourShotCK.ca) or by calling 519-351-1010.

COVID-19 vaccines can be given at any time before or after non-COVID-19 vaccines.

Both the Pfizer and Moderna bivalent vaccines will be available at the CK Public Health vaccination clinics. When booking your COVID-19 bivalent vaccine appointment, simply register for the timeslot that works best for you, and you can choose which vaccine you would like once you arrive to the clinic (Individuals must be 18 years of age to receive the Moderna bivalent vaccine)

Individuals infected with COVID-19 after completion of their primary series, who are currently eligible for a booster, are recommended to receive booster six months after infection.  As per NACI, emerging evidence indicates that a longer interval between SARS-CoV-2 infection and vaccination is associated with improved antibody responses to COVID-19 vaccines.

*A previous infection with SARS-CoV-2 is defined as a COVID-19 case confirmed by a molecular (e.g., PCR) or rapid antigen test, or symptomatic AND a household contact of a confirmed COVID-19 case.
