Stanley Plotkin's testimony is no ordinary testimony (he is also a pediatrician )

The Wistar Institute of Anatomy and Biology
During his time at Wistar, Plotkin worked on several vaccines; chief among them are vaccines for rubella, rabies, rotavirus, and cytomegalovirus (CMV). He developed a vaccine for rubella, based upon the RA 27/3 strain of the virus (also developed by Plotkin using WI-38 human fetal stem cells), which was released to the public in 1969.[9] This vaccine led to the eradication of the disease in the United States, according to the Centers for Disease Control and Prevention, in 2005.[10] Plotkin, working with Tadeusz Wiktor and Hilary Koprowski, produced a human vaccine for rabies during the 1960s and 1970s. This vaccine can be used as a preventative measure for people who have an increased risk of contracting rabies, as well as a treatment for those who have been exposed recently to the disease, preventing infection in nearly 100 percent of cases.[10] Another vaccine that Plotkin co-developed, working with H. Fred Clark and Paul Offit, is for rotavirus. In 2006, the team's vaccine became part of the U.S. recommended vaccine schedule for babies.[10] In the 1970s, Plotkin led the development of an experimental vaccine against CMV. This vaccine, developed using attenuated CMV, has yet to make it into commercial production.[10]

Dr. Plotkin has been a tireless advocate for the protection of humans, and children in particular, from preventable infectious diseases. His lifetime of work on vaccines has led to profound reductions in both morbidity and mortality not only in the United States, but throughout the world. His unbending adherence to the principle of being guided by outstanding science has led him to be admired by his peers. He demonstrates the combination of scholar, scientist and public servant exemplified by Dr. Maxwell Finland.
