This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book aims to spread like wildfire, eventually reaching the shores of the United States. In fact, the World Health Organization declared COVID-19 to be a pandemic in late January 2020.

Probably the best formulation of chemicals for a novel COVID-19 virus comes from the family of derivatives that originate from the “Guanosine” family. Determination of the specific criterion which will make an effective vaccine, especially for the delta variant of the novel COVID-19 vaccine, can be an extremely difficult task as there are so many variables that need to be taken into consideration.
