Matt Crawford speaks with author Fabrice Delaye about his book, The Medical Revolution of Messenger RNA. To the casual observer, it took about 10 months to develop the COVID-19 vaccine. That extraordinary success was made possible by decades of research and development in the use of messenger RNA (mRNA), the molecule that instructs cells to make a protein that stimulates production of antiviral antibodies. Fabrice bring us to back to the discovery of and evolution leading up to mRNA being used to treat this global pandemic and the scientists and companies who developed and produced it. A layperson's perspective, this book will make this subject easy to understand for all its readers.
