Congratulations to Christopher Rutty on his new article in The Canadian Encyclopedia, “Canadian Lipid Nanoparticle Research: The Key to COVID-19 mRNA Vaccines.” Chris’ article describes the ground-breaking work of Pieter Cullis, Michael Hope, and Thomas Madden at the University of British Columbia in studying and developing lipid nanoparticles systems for drug delivery. In addition to many important applications such as delivering anti-cancer drugs to tumours, their research made possible the unprecedented speed with which COVID-19 mRNA vaccines were developed and delivered amid a global pandemic.
