Abstract
On October 29, 2021, the Public Health Agency of Canada (PHAC) released interim guidance from the National Advisory Committee on Immunization (NACI) on booster doses of COVID-19 vaccines. These recommendations are based on current scientific evidence and NACI's expert opinion.
NACI reviewed the evidence on the need for, and benefit of, a booster dose of a COVID19 vaccine following a primary series in various populations. NACI used a decisionmaking framework to help guide ethical and evidence-informed decisions.
