They are very different.
The Vampire Diaries and True Blood
True blood
This is hard because vampire diaries is so original and amazing. The secret circle on the cw was very similar, but for a younger audience. However that show has now been cancelled. Vampire diaries is like a toned down true blood where noone's safe and emotions run really high.

Moonlight, True Blood, The Vampire Diaries, Being Human, Buffy The Vampire Slayer
Buffy The Vampire Slayer
There has been the Twilight movies, Vampire Diaries, and Vampire Academy as well as True Blood.
True Blood is the greatest show ever! Well, it is one of the greatest shows ever! It is a lot more dark and sexual then being human and vampire diaries but definitely worth watching! If your going for a supernatural kind of vibe, then Supernatural is really good and so is Once Upon a Time.

In different legions vampires only have to bite humans for them to become vamires. In vampire diaries You have to drink the blood of a vampire, die with the blood still in your system and feed on human blood for the transformation to be complete. In True Blood a vampire has to give you there blood, you die and are buried with your master until you raise as a vampire. Any of this helpful? Well these are just examples of how a human is transformed to a vampire. But in the real world unfortunately there are no vampires.
Do you mean is a vampire true? Yes. Sang (blood drinkers) and Psychic ones.
