Boats, planes, helicopters: Canada gears up to vaccinate remote indigenous communities By Moira Warburton FILE PHOTO: Vials and medical syringe are seen in front of Moderna logo in this illustration TORONTO (Reuters) – Canada’s indigenous communities have been prioritized for the COVID-19 vaccine but distributing it across difficult and remote terrain will be a challenge, as authorities deploy small planes and boats to ship the drug. Canada approved drugmaker Moderna’s vaccine on Wednesday, which most indigenous communities are expected to use because it remains stable at 2-8 Celsius (36-46 Farenheit) for 30 days, unlike Pfizer’s, which needs to be stored at -70 degrees Celsius and is only stable for a few days after thawing.
