Vampire isn't much of a problem when you can Flambé them.
Or when you can Flambeau them.
Ars Magica/Mage: The Ascension joke literally no one here is going to get.
Basically just what
Avaron1974 said - try to leave out any preconceived notions of how the various supernaturals "function" in traditional lore.
The real problem is that "traditional lore" is barely a thing anyway.
Werewolves and vampires barely have anything to do with each other in the original folklore. About the only real connection was that both were supposedly the product of black magic or deals with the Devil. The idea that they're rivals who constantly fight is
extremely new (easily late 20th century), and is mostly the product of Hollywood. In fact, most of what we think we know about werewolves in general (weakness to silver, ties to the full moon, a contagious bite, a half-man/half-wolf form) almost
entirely comes from the Universal horror movies of the 40s. Which is probably around the first time people started thinking about vampires and werewolves together as well (around the time Universal was going to do the Wolfman vs. Dracula movie). Things get even more complicated when you start looking at the vampires and skinchangers of
other cultures (which can easily be different from Eastern European folklore).
In European folklore (what most people think of when talking about Gothic Horror), werewolves were mostly just witches or warlocks who used magic to transform into animals (in this case, specifically wolves). Basically, you make a deal with the Devil, and he teaches you the black magic you need to use to transform. That's pretty much it.
And yes, that does in fact mean that Tara would easily fit certain traditional definitions of what a "werewolf" actually is.
Vampires were pretty much the same way. Most of what we think we know about them comes from movies, not folklore. They were never allergic to the sun until Nosferatu came out (which is around the same time you started getting more monstrous looking vampires).
They were the ones who were originally repelled by silver (because silver was seen as being "pure" and thus able to resist evil), which is also why they don't have a reflection (early mirrors were backed with silver) or show up in photographs (because early photography used silver) - neither of which should be a problem
now (since neither use silver anymore). Most modern stories ignore the fact that they were super OCD (and had to stop and count every grain of wheat or rice if you threw a handful at them while they were chasing you) and couldn't cross running water - unless you're dealing with a smartass who throws stuff like that in just to look clever.
And yes, that does in fact mean that The Count from Sesame Street is one of the more accurate representations of a classical vampire you'll ever see on television.
Honestly, any story involving vampires or werewolves (or the lack thereof) can describe them in pretty much any way they want to - odds are there's already been a myth or a story or a movie out there that describes them similarly anyway. There's really no ONE TRUE WEREWOLF or ONE TRUE VAMPIRE that is the baseline accurate definition and everything else is wrong.
Except vampires that glitter in sunlight. That shit's just 100% wrong.
