Wow this book is something that VCE students in year 11 and 12 that study biology as well as our science teachers too. Another group for any who want to really want to know Covid-19 vaccines. This book in the language that is easy for most people to access this and understand not just the discoveries but all so the drama that can occur behind the scenes. Hopeful this book can encourage others into the this field for the future. I listen to the audio version and narration you fantastic well worth the listening.
