The company’s technology uses plants to grow virus-like particles that mimic the peplomers that cover the coronavirus.
A Canadian pharmaceutical company said its plant-based COVID-19 vaccine has shown strong protection against the virus and will soon seek approval at home and elsewhere.
Medicago announced on Tuesday that a double-dose vaccine is 71% effective in preventing COVID-19 infection in a large late-stage study involving several variants, including the delta variant. The company’s results did not include new Omicron variants that were not in circulation during the study period.
The Quebec City company said it has also begun the process of seeking Canadian approval “soon” and submitting it to regulators in the United States, the United Kingdom and other countries. The company also said it is preparing to send the data to the World Health Organization.
Medicago uses plants as a living factory to grow virus-like particles that mimic the peplomers that cover the coronavirus. Our UK partner, GlaxoSmithKline, provides an immunopotentiating chemical called a vaccine adjuvant.
With numerous COVID-19 vaccines deployed worldwide, health authorities around the world are looking for additional candidates in the hope of increasing supply in developing countries. As Omicron variants spread, experts warn that the coronavirus will continue to propagate unless vast parts of the world are vaccinated.
The Medicago study enrolled 24,000 adult volunteers who received either vaccines or dummy shots and were followed up to track COVID-19 infections and complications. They received two shots every three weeks.
According to the company, no serious safety issues were detected and common side effects such as fever and malaise were “mild to moderate” and resolved within 3 days. The results have been published in a press statement and have not yet been independently reviewed by experts.
