To be clear, Targaryens are not immune to fire, only resistant. This was confirmed by GRRM on his blog, " So Spake Martin ", after people kept asking him if Dany was immune to fire after she survived Drogo's funeral pyre in season 1. He answered no, it was blood magic, she is not immune to fire, nor are any Targaryens. They're fire-resistant, but not immune.

To illustrate this GRRM wrote a scene with Dany burning herself in the fifth book :P

"Her skin was pink and tender, and a pale milky fluid was leaking from her cracked palms, but her burns were healing."
