The National Advisory Committee on Immunization (NACI) is a Canadian advisory body operating within the Public Health Agency of Canada (PHAC).[1] It is tasked with “providing guidance on the use of vaccines currently or newly approved for use in Canada to the Government of Canada.”[2]
NACI was formed in 1964.[2:1]
On April 23, 2021, NACI recommended the AstraZeneca-Oxford COVID-19 vaccine be offered to “all Canadians over the age of 30, but only when the benefits outweigh the risks of rare, serious post-vaccine blood clots.”[3]
On June 29, 2022, NACI issued guidance recommending “booster doses” of COVID-19 vaccines for all “Canadians at increased risk of serious illness from COVID-19,” regardless of how many doses they had previously received.[4]
On March 3, 2023, NACI called for “high-risk individuals” to receive another booster dose in the spring.[5][6]
On July 11, 2023, NACI once again strongly recommended that all individuals over the age of 5 receive a "primary series" of COVID-19 vaccines, with a less emphatic recommendation for those aged 6 months to five years. They also recommended an additional dose of "the new formulation of COVID-19 vaccine for individuals in the authorized age group if it has been at least 6 months from the previous COVID-19 vaccine dose or known SARS-CoV-2 infection."[7][8]
