Dear London, 
Yes, it is safe to a Vampire PRP treatment 6 months after having Sculptra and it will be safe as there is no contraindication. 
Sculptra is an injectable cosmetic filler that can be used to restore facial volume lost due to aging or illness. It contains poly-L-lactic acid (PLLA), a biocompatible synthetic substance that stimulates collagen production and it can be used to treat deep lines, creases, and folds to give a more youthful appearance.
Whereas, Vampire Treatment - PRP treatment have an incredible ability to brighten the face, making it look more plump, hydrated and healthy as well as free from fine lines and wrinkles it is done by isolating the growth factor from the patients blood after which a micro-needling device to create multiple micro-punctures; both driving the isolated growth factors into the skin & creating stimulus for tightening and rejuvenation of the collagen of the face. Then the practitioner paints the growth factors onto the micro-punctures so that the growth factors soak into the tissue for further stimulation of tightening and skin rejuvenation.
The skin tightens, and glows with color, and scaring softens for a beautiful younger and very natural result. 
Any adverse reactions are rare, but your practitioner may use a topical anesthetic cream before injection the PRP. You may feel a tingling sensation after the procedure and there may be redness, slight swelling and bruising. These symptoms will soon disappear and the results will be apparent after 3-6 weeks.
