A virus
A virus.
A virus is a non-living pathogen that invades body cells to replicate and cause infection.
It is grown in living cells and the antigens that cell makes are what will be in the vaccine. These then are purified and stabilized. The Salk vaccine involves using viruses that have been inactivated by using formalin. Heat would not inactive the virus.

outside a living host cell , a virus is found to be inactive , devoid of its metabolic activities . but inside a living cell it actively carries out all its metabolism . so sometimes it is living and some other times non living
Microorganisms are living things that are so small that they can not be seen by the naked eye. When a microorganism causes a disease it is then called a pathogen. A host is a scientific term used to refer to whatever the pathogen is living in. So a host could be an animal, such as a human, or even a plant. An infection occurs once a pathogen enters a host. Disease occurs after infection once the pathogen disrupts homeostasis, or "the balance", in the host's normal functions. The study of this process is known as pathology, and the process of a disease being caused by a pathogen in a host is called pathogenesis.
organelles
There is no such thing. viruses are so very small that a living thing could not live inside one. But a virus inside a living thing could be called latent if it is not causing a disease or active if it is.

Biologist
A pathogen is a microorganism that causes disease such as bacterium and viruses. All viruses are pathogens, which means they all cause disease it causes disease But a pathogen is a living organism and a viru s is not so its really argumentive.
