It has been a long and painful pandemic but the light at the end of the tunnel is within our sights. While there are many reasons for what will surely be a celebration, there is one one particular medical advancement that has raised all of our spirits and may represent the future for battling disease. It’s the mRNA vaccine. This week, we’re closing out our season on COVID-19 science with a guest we all need to hear. He is Pieter Cullis and he a Professor in the Department of Biochemistry and Molecular Biology  at the University of British Columbia. He is one of the founders of mRNA vaccine technology, although when he started this journey over four decades ago, there was a very different reason for the work. It’s a story you need to hear to truly get a feel for the miracle that is mRNA vaccines.  I want to thank everyone who asked a question over the course of this season. It helped to make the show interactive and also more informative. If you have any questions, you can still reach me on Twitter or by Email. Have a great summer and I look forward to better times and awesome science.  Twitter: @JATetro Email: [email protected] Guest: Pieter Cullis https://biochem.ubc.ca/person/pieter-cullis/  See omnystudio.com/listener for privacy information.
