Following provincial direction, starting today, Monday, December 20, 2021, residents 18 years of age and older (born in 2003 or earlier) can book an appointment to receive a third dose of COVID-19 vaccine through Halton’s online booking system. Appointments may be limited.
"Thank you to our incredible clinic team who are working hard to vaccinate as many people as possible, especially as we head into the holidays," said Halton Regional Chair Gary Carr.
"In addition to our clinics, first, second and third doses are available at over 100 local pharmacies, participating doctor’s offices and the GO-VAXX bus that will be making stops at markets and malls in our community."
All third dose appointments at Halton’s Community Vaccination Clinics must be booked through Halton’s online booking system. Please only call 311 if you require immediate support.
Halton Region is asking for patience from the community as they work to provide third doses to residents age 50+ and immunocompromised groups, in addition to prioritizing doses for 5 to 11 year olds.
"With the rapid spread of the Omicron variant, it is important for all Halton residents to continue to do their part," said Dr. Hamidah Meghani, Halton Region’s Medical Officer of Health. "This includes reducing your contacts with others as much as possible by switching to virtual gatherings and limiting in-person gatherings, staying home when sick even with mild symptoms, and getting vaccinated with your first, second or third dose when you can."
She continues, "All Health Canada approved vaccines are safe and effective and the first vaccine available to you is the best option to provide protection against COVID-19, including Omicron. Thank you to everyone for their patience as we work to get third doses to those most at-risk right now and for continuing to do your part."
