Scientists have injected the first human patient with a new cancer-killing virus.

The virus, known as Vaxinia, has seen successful tests in animals.

However, scientists are using a new cancer-killing virus known as Vaxinia in an experimental cancer treatment.

The virus itself has been engineered specifically to kill cancer cells.

And, in previous animal trials, scientists have seen very promising results.

This time around, though, the scientists have engineered the cancer-killing virus to not only harm cancer cells, but also to make them more recognizable to the body’s immune system.

Of course, before moving on to the human tests, the scientists tested the virus on animals.

There are a lot of reasons for this, obviously, but the researchers are hopeful this virus could improve patients’ chance to fight back against cancer.
