Are viruses living things

Answer 1

A virus is a parasitic organism that attaches to a bacteria and multiplies by taking it's sustenance from the bacteria. It fulfills the basic definition of life to biologists: It has the ability to replicate itself. There is still debate over this, but most scientists believe viruses are living entities, though some describe them as being "at the edge of life". Vaccines to prevent infection by certain viruses fall into two types: live vaccine and dead vaccine. Vaccines are made from the virii themselves. Logically, you cannot make a live vaccine from a non-living thing. There is an even smaller, less understood relative of viruses called a "viroid", which is not well understood as of yet.

Answer 2

Viruses are considered by some scientists to be non-living entities because they cannot carry out all the functions of life on their own. They need a host cell to replicate and survive.
