Crosses: Crosses are a mere annoyance than anything to elders, newer vampires would get burned /if/ it touched them. Elders would simply regenerate the damage and shrug it off.

Silver: Silver hurts, period. Newer vampires, again, are weaker. Elders, while still vulnerable, will heal it at a moderate pace, the flesh slowly forcing the silver out as it regrows.

Holy Water: New vampires worst enemy, especially vapor. Elders, In great amounts proves troublesome, small amounts you are basically poking them with a damned toothpick.

Running Water: Does jackshit to anything, ever.

Blessed Iron: Neh...Concept seems a bit...eh. Not sure how one would bless a chunk of metal..

Dead Man's Blood: Hinders healing powers, large doses can damage. Almost useless, but handy in a pinch.

Poison: Younger vampires could be susceptible, depending on age. Does nothing to elders, whatsoever.

Acid: What hurts flesh, hurts flesh. That simple.

Stakes: RIP

Sunlight: Possibly slightly annoying, does nothing other than that

Did I miss anything? :D

Garlic, Holy Wafers (basically anything sacred or blessed to Judeo-Christianity, although frankly it is really the faith of the one holding the symbol, not the symbol in itself), Fire, Decapitation, Old Magic (and all enchanted weaponry).

Although I'm not sure if the other genres of vampires are truly bound by this list. Perhaps one weakness must be replaced with another.
