Fighting Back AIDS researchers continue to make progress in battling HIV, addressing the fight with a variety of new and promising approaches...but this NOVA Hot Science isn't about the fight against the AIDS virus. Fighting Back instead takes a look at the battlefield where the fight takes place, putting you into the world of the immune system. A mumps virus enters the body, then enters a cell. There it makes copies of itself. How does the immune system respond? It's up to you to figure it out. A play-by-play explanation will follow, as well as an explanation of what makes an attack by the AIDS virus unique...and devastating.
