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.
vaccination
the inactive form still has the antigens (protein markers) specific to that pathogen on the surface. the immune system develops specific responses to this pathogen when it is encountered after a vaccination. as it is inactive the person does not suffer the effects of this pathogen, but when an active form is encountered later the immune system is quicker to respond due to the fact that it now recognises those antigens.

The inactive form of the pathogen still has the antigens (protein markers) specific to that pathogen on their surface. Antibodies locate the pathogen and create the correct form of antibody to combat it. As it is inactive the person does not suffer the effects of this pathogen, but when an active form is encountered later the immune system is quicker to respond due to the fact that it now recognises those antigens.
A virus.
They are called "bacterial pathogens".
Technically a 'pathogen' IS measels. A pathogen is a fancy name for Bacteria. And a pathogen is a bacteria that IS a certin disease. Hencforth, the answer to your question would be measles IS its own pathogen.
In a vaccination you will receive a version of the pathogen (disease) that can not make you sick because it is inactive or significantly weakened. It will be introduced into your body with an injection or sometimes using oral or nasal formulations. Your immune system will then produce antibodies, which will kill or deactivate the introduced pathogen. Therefore, if an active/live pathogen would enter your body later, your immune system would be quickly able to produce more of the same type of antibodies, as they will recognizethe organism that caused the infection and know what antibodies will work on it. Boosters then might be used over the years to essentially remind the immune system how to defend your body against the pathogen.
A virus
Sometimes bacteria is the pathogen involved.
The term pathogen most commonly is used to refer to infectious organisms. The inactive form of a virus is called a provirus. -ChaCha Answers
