The "Godfather of Vaccines", Stanley A Plotkin, is the world-renowned American physician who works as a consultant to vaccine manufacturers, such as Sanofi Pasteur, as well as biotechnology firms, non-profits and governments. In the 1960s, he played a pivotal role in discovery of a vaccine against rubella virus while working at Wistar Institute in Philadelphia. Plotkin was a member of Wistar's active research faculty from 1960 to 1991.

In addition to his emeritus appointment at Wistar, he is emeritus professor of Pediatrics at the University of Pennsylvania. His book, "Vaccines," is the standard reference on the subject. He is an editor with Clinical and Vaccine Immunology, which is published by the American Society for Microbiology in Washington, D.C.

In 2017, Plotkin agreed to be an expert witness for a court case in Michigan. This is the unaltered transcript from the legal deposition of that case and is an unprecedented look into the mind of perhaps the most knowledgeable authority in the field in an honest and thorough interview by one of the foremost legal minds in the world, Aaron Siri.
