Canada Approves First Plant-Based COVID-19 Vaccine

As Sanofi SA SNY and GlaxoSmithKline Plc's GSK COVID-19 vaccine finally heads to regulators, another shot using GSK's pandemic adjuvant has won its first global approval.

  • Mitsubishi Tanabe Pharma Corporation-backed Medicago's recombinant COVID-19 vaccine, dubbed Covifenz, has snagged a green light in Canada in individuals 18 to 64 years of age.
  • The vaccine uses a plant-based virus-like particles technology to mimic the coronavirus' spike protein and is combined with GSK's pandemic adjuvant.
  • Covifenz marks the first approved vaccine for Medicago and the first nod for a COVID shot using GSK's pandemic adjuvant.

  • In a Phase 3 trial conducted in more than 24,000 adults, Covifenz showed a 71% efficacy against COVID-19 by various SARS-CoV-2 variants, though not omicron because the now-dominant variant wasn't present at the time of the study.
  • The virus-like particles platform allows Covifenz to be stored at normal refrigeration conditions from 2 degrees Celsius to 8 degrees Celsius. Two doses of the vaccine are given intramuscularly 21 days apart.
