Antibodies
it prompts the body to produce immunity to a disease:)
Vaccine
When you receive a vaccine, it puts a "dead" version of a virus into your body; it is one that cannot reproduce, but instead causes your body to produce anti-bodies that fight infection. When you come into contact with that virus, you already have anti-bodies to fight the virus in question. In the event that you ALREADY have the virus, do not receive the vaccine. It is not going to properly do its job. So, to give a more direct answer, it doesn't effect reproduction, it simply gives your body a warning that it might show up so that it is prepared.

matabolism
A vaccine stimulates the body to produce antibodies against a specific disease causing pathogen. This makes the body able to fight off that disease.
A horse should receive a tetanus vaccine annually. This is a preventative measure, as the causative bacterium (Clostridium tetani) is ubiquitous in the environment and horses are extremely sensitive to the exotoxins that produce clinical signs of tetanus.
vaccine
The vaccine is made of weakened virus particles. This causes your body to produce interferon to fight an infection. :-)
The small does introduces the body to the disease, (small amounts) so the body then can produce antibodies, so that when the body is exposed to it, it can fight it off.
You are giving the definition of a vaccine but not "what is the following to choose from"
