More data needed before recommending AstraZeneca COVID-19 vaccine for seniors: Tam

Canada's chief public officer of health Dr. Theresa Tam said on Tuesday that more “real-world data” is still needed after the National Advisory Committee on Immunizations recommended that the newly-approved COVID-19 vaccine from AstraZeneca not be given to those 65 or older. However, she said "don't read their recommendations as sort-of static, they will update as needed.”
