This book summarizes the development and statistical validation of a guinea pig model as an alternative for potency testing of the viral antigens included in combined vaccines applied in cattle to control the respiratory, reproductive, and neonatal calf diarrhea syndromes. The model allows, in one serum sample, to test the vaccine quality for all the viral antigens included in aqueous as well as in oil-adjuvanted formulations of bovine vaccines. The methodology proposed for the control of bovine herpes virus, parainfluenza, and rotavirus were recommended by CAMEVET as guidelines for the 30 countries in the forum, including the US. Key Features Reviews combined vaccines used for cattle Summarizes animal models used for vaccine testing Focuses on bovine herpesviruses, rotaviruses, parainfluenza, and bovine viral diarrhea virus Provides guidance on the effectiveness of the Guinea Pig model for testing vaccine immunogenicityIn AI Superpowers, Kai-fu Lee argues powerfully that because of these unprecedented developments in AI, dramatic changes will be happening much sooner than many of us expected. Indeed, as the US-Sino AI competition begins to heat up, Lee urges the US and China to both accept and to embrace the great responsibilities that come with significant technological power. Most experts already say that AI will have a devastating impact on blue-collar jobs. But Lee predicts that Chinese and American AI will have a strong impact on white-collar jobs as well. Is universal basic income the solution? In Lee's opinion, probably not. But he provides a clear description of which jobs will be affected and how soon, which jobs can be enhanced with AI, and most importantly, how we can provide solutions to some of the most profound changes in human history that are coming soon.
