Chryzinium: The Lazarus VI Project

What If... You or a loved one were dying of cancer, and had access to a vaccine that would allow you to live decades beyond a normal life span, disease-free. Would you consider it? But, there's a catch! While the Chryzinium vaccine may guarantee an extended, healthy life, it irrevocably alters DNA to the point where its recipients may not even be considered human. And the unearthly entity that offers this vaccine monitors and controls all who take it, 24 hours a day, 7 days a week. Would you still consider it?
