The Organic Tech tree has a medical facility that can prevent plagues of a certain lvl based on it's lvl. Up to lvl 3 plagues.
Personally, I think -that- should be available to regular tech. The other facilities that improve population growth to astonishing levels can stay in organic, but the medlabs should be available to everyone.

"What do -you- want?" "I'd like to live -just- long enough to be there when they cut off your head and stick it on a pike as a warning to the next ten generations that some favors come with too high a price. I would look up into your lifeless eyes and wave like this..." *waggle* "...can you and your associates arrange that for me, Mr. Morden?"
