TORONTO — Researchers at McMaster University in Hamilton, Ont., have been approved to begin human trials on two Canadian-made COVID-19 vaccines that are delivered by inhaled aerosol to target the lungs and upper airways.

In a release Tuesday, McMaster said researchers would test the safety and immune potency of the inhaled vaccines during Phase 1 of clinical trials they recently received Health Canada approval to begin. Both inhaled vaccines are intended to act as boosters to be administered to participants who have previously received two doses of a COVID-19 mRNA vaccine such as Pfizer or Moderna’s.
