Do vampires walk in daylight

Vampires, under standard conditions cannot walk around in daylight as daylight kills them. But if the creature was a Hybrid (A cross between a Vampire and a human being or a Vampire and a werewolf), then they could walk around in the sun, as they would posess the strengths of both breeds and the weaknesses of none. (Ref: The Underworld) However, in more recent times,(Ref: Blade) the Vampires have incorporated High levels of technology, based on Cell stem research and bio engineering to come up with serums that allow them to walk around in sunlight without fear of harm for limited periods of time. Vampires cannot walk in daylight or at noght they are entirely fictional hybrids can walk at day and at night
