Because a vaccine is a little bit of a weakened or dead virus to trick your immune system into thinking that you have the disease so that it creates the antibodies to fight the disease. This prevents you from getting the disease. If you already have the disease, then it won't do much.
A vaccination is a dead or weakened virus. It is sort of like a training dummy for your white blood cells. The viruses go in and train the white blood cells to attack it, to make it familiar with the virus for when the real thing comes up. Pretty much, if your body is already infected, then it doesn't help if more viruses go into your body.

How can a vaccine affect a viruses reproduction?
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.

How does a vaccine prepare the immune system of the body?
A vaccine normally exposes the body's immune system to dead portions of the virus it is trying to protect against. The immune system will still react to the dead virus and develop anti-bodies to protect against the virus. This will either prevent the person from becoming infected or reduce the length and the severity of the symptoms if they do become infected.
Do vaccines work if you already have a virus?
Yes, they can, depending on the virus you have. Immunocompromised people with the HIV/AIDS virus may not get full immunization from a vaccine since their body doesn't respond to infections like other people's bodies. If it is a flu virus, there is no problem getting a vaccination unless you have a high fever from the virus. They will ask you about any recent fevers when you go to get the vaccination. The problem if you are sick with a virus is that your body's immune system is working very hard to get rid of the virus you have, if you add the vaccine for a different virus to your body, it has to work twice as hard to deal with both at the same time, and you may not get a good response to the vaccine.
