It would depend on what the author of the fictional story wanted
No, because vampires do not exist. You cannot affect anything that does not exist. But that said, it was indeed believed that the holy powers of silver would be extra-damaging to vampires, which were unholy.

The notion of silver harming vampires comes from Marvel Comics. From there, it made it's way into popular culture in movies and television. Silver does not affect vampires in the folklore. It doesn't even harm werewolves either for that matter. The use of silver as a weapon against monsters began with the Wolfman film of the early 1940's. Sunlight does not traditionally harm vampires either. That began with Nosferatu (the 1922 silent film).
In popular lore, vampires are often believed to be harmed by silver, similar to other supernatural creatures like werewolves. However, the idea of silver harming vampires is not as consistent or widely accepted as other weaknesses like sunlight or garlic.

Since vampires do not exist, they have no effect on the Catholic Church.
Objects that are traditionally believed to ward off vampires include garlic, holy water, crucifixes, and silver items. Garlic is thought to repel vampires due to its strong odor, while holy water is considered blessed and protective. Crucifixes symbolize faith and can be used to defend against evil. Silver, often associated with purity and protection, is also said to be effective against supernatural beings.
Only if you shoot them with a silver bullet, I've seen vampires wear silver jewellery.
No that's werewolves, in most stories vampires hate garlic and can be killed with a wooden stake.
There is no evidence to support the supposition that Vampires exist. However even if they do, it is not advised to go on a Vampire Hunt unless you are a professional, but items that are essential in hunting Vampires at least from the mythos are: 1. Garlic: In most appearances Vampires are weakened by Garlic if not out right deathly allergic to it. 2. Wooden Stake: In most appearances a wooden stake through the heart is the only sure fire way to finish off a Vampire 3. Crucifix: In most appearances Crucifixes weaken Vampires considerable 4. Holy Water: Blessed by a Priest it tends to burn the flesh of Vampires. This is a good benchmark to test if something really is a Vampire, because Holy Water generally has no affect on individuals 5. Eucharist: Same as the aforementioned Holy Water 6. Silver: In some appearances Silver is deadly to Vampires, in others it has little or no effect on them at all. 7. Fire: Many Vampires are afraid of fire and are weak to it.
if they are virgins or werewolfs or vampires or Justin beiber then you have to kill them with a silver bullet
vampies do not feel "burned" when in contact with silver but it does mess with thier head.
