Summary: Roughly 80 percent of the U.S. population is infected with the herpes virus. While the virus is very easy to get, it remains dormant in many people, who never even know they have it. This is partly because it effectively evades the immune system, taking up refuge in the central nervous system.<br> <br> Dr. Greg Smith is a herpes expert. He is a professor in the microbiology-immunology department at Northwestern University’s Feinberg School of Medicine. <br> <br> His research on herpes looks at novel targets for antivirals and engineering recombinant viral particles as effective gene delivery vehicles. <br> <br> In this episode, Smith talks with STEM-Talk host Dawn Kernagis about his educational and research path to becoming a herpes expert. He also touches on polio as an example of an earlier virus that was largely defeated, and how that was different than herpes. Finally, Smith touches on the development of viral vectors and vaccines to win against the more severe forms of herpes that some people are genetically predisposed to get.<br>
