Beginning Sunday, June 20, individuals 18 years or older who have an appointment booked at one of the city-run immunization clinics will receive a Moderna mRNA vaccine. Anyone over 18 years can safely receive the Moderna mRNA for their first dose or second dose.
- The Moderna and Pfizer vaccines are similar with near-identical efficacy rates. The “mixed mRNA model” (mixing Pfizer and Moderna for first and second dose) as well as a first dose of the AstraZeneca vaccine followed by a second dose mRNA vaccine is approved by both the federal and provincial governments.
- Canada’s National Advisory Committee on Immunization (NACI) has found “no important difference” between Moderna and Pfizer and considers these mRNA vaccines interchangeable.
- The Pfizer mRNA vaccine is the only vaccine currently approved for use in Canada for anyone under the age of 18. At this time, youth receiving their first dose of vaccine will only receive the Pfizer mRNA vaccine.
- Clinic staff will ensure clients are aware of which vaccine brand they will be receiving, however, there will be no opportunity for clients to request or switch to a particular vaccine brand. The limited Pfizer mRNA vaccine supply will be reserved and administered to youth 12 to 17 years old.
