Canada authorises first plant-based COVID-19 vaccine
Canadian regulators said Thursday Medicago's two-dose vaccine can be given to adults ages 18 to 64, but said there's too little data on the shots in people 65 and older.
The decision was based on a study of 24,000 adults that found the vaccine was 71% effective at preventing COVID-19 - although that was before the omicron variant emerged. Side effects were mild, including fever and fatigue.
Medicago uses plants as living factories to grow virus-like particles, which mimic the spike protein that coats the coronavirus. The particles are removed from the plants' leaves and purified. Another ingredient, an immune-boosting chemical called an adjuvant that is made by British partner GlaxoSmithKline, is added to the shots.
While numerous COVID-19 vaccines have been rolled out around the world, global health authorities are looking to additional candidates in hopes of increasing the worldwide supply.Quebec City-based Medicago is developing plant-based vaccines against multiple other diseases, and the COVID-19 vaccine may help spur more interest in this new method of medical manufacturing.
