Seemed designed well enough to me, blast doors, bullet proof/shatter proof glass. Self sufficient power source (diesel only last so long lol). A fail safe to ensure the viruses dont get out. Lets be honest a CDC in a city is a good idea. Why? Where else can you get so many samples? Where people thrive, after that you e-mail or secure transport all the findings to a more isolated place. I am no security's or disaster planner but makes sense to me.
