Could the "real vampire" be the creature, what cells will renew in the extreme short cycle?

Sometimes there have been movies, where man is turning to a vampire, and that creature cannot be killed by using normal bullets. So I sometimes wonder, what kind of thing that kind of creature could be. Could the vampire be the creature, what tissues will renew in a very short cycle, and this renewing process would make them unable to get injuries by the mechanic objects? That thing would make that kind of creature extremely vulnerable against electromagnetic radiation, and even the short period staying in the sunlight would cause terrible burning injuries.

If the tissue would renew as fast as in the films, the thing is that this creature would need the NBC protecting suit while walking in the sunlight. And if that creature would be real, that means that the cells what it has might be in the edge to transform to the cancer cell. If that hypothetical organism would acting like transforming another species,  it would need a very specific immune system.

That thing means that it must have tanks or some kind of things, where it has stored the viruses, which can release in the body. The thing is that if the creature would have the ability to transform another species the DNA must change in its cells by each cell at the same time. That kind of ability would be real imaginational, and that vampire can change its form to the swarm of insects.

In that case, the renewing the tissues would happen so fast, that the bullet holes and another kind of things would fix themselves or the cells would close the wound channel. If that kind of creature, what cells are renewing in a very fast period would have existed, that creature must protect itself from the ultraviolet radiation. The extreme fast renewing tissues are really vulnerable and able to get cancer is very big.

But those creatures might be very vulnerable if they are targeted by electromagnetic radiation, because of the fast period of the cleavage, because in that period, the genomes inside the cell are separating, and the genetic material will be visible. If the genomes are targeting the electromagnetic radiation at that moment, that would cause damages in the DNA molecule. That damage is the thing, what is called as elding would cause also cancer.
