A Canadian drugmaker says its plant-based COVID-19 vaccine showed strong protection against the coronavirus. Medicago said Tuesday that its two-dose vaccine was 71% effective in preventing COVID-19 infection in a large, late-stage trial. It included several circulating variants, but not the emerging ommicron variant. The company’s technology uses plants to grow virus-like particles, which mimic the spike protein that envelops the coronavirus. The company will soon seek approval from Health Canada and has begun filing with regulators in the US, UK and other countries. It is also preparing to send its data to the World Health Organization.
