Ontario Recommends Pfizer COVID-19 Vaccine for People 18-24 Years Old
Ontario issued a preferential recommendation of the use of Pfizer-BioNTech vaccine for individuals aged 18-24 years old effective immediately based on the current available analysis from Ontario’s adverse events following immunization (AEFI) surveillance system.
This recommendation was based on the advice of Ontario’s Children COVID-19 Vaccine Table, Ontario Vaccine Clinical Advisory Group, and Public Health Ontario and is due to an observed increase in Ontario of the very rare heart condition called pericarditis/myocarditis following vaccination with Moderna compared to Pfizer in the 18 to 24 year old age group, particularly among males. The majority of reported cases have been mild with individuals recovering quickly, normally with anti-inflammatory medication. Symptoms have typically been reported to start within one week after vaccination, more commonly after the second dose.
Should individuals aged 18 to 24-year old wish to receive Moderna they can continue to do so with informed consent.
Also note, the province and HPEPH will continue using the Pfizer vaccine for youth ages 12-17 (including those turning 12 in 2021).
A full updated version of the NACI recommendations on the use of COVID-19 vaccines was released on September 28, 2021.
