Medicago vaccine approved for people aged 18 to 64.
Health Canada has authorized the use of the first made-in Canada COVID-19 vaccine.
Medicago's two-dose plant-based vaccine has been approved for anyone aged 18 to 64.
Health Canada says the vaccine's effectiveness and safety for anyone outside of that age bracket has not been determined yet.
The dosing schedule is 21 days apart, and clinical trials suggest the vaccine was 71 percent effective in protecting against COVID-19 one week after the second dose.
The Quebec company submitted data to Health Canada in December.
