When the vaccine gets to the body the it will block away the viral infection.
There is no specific vaccine for viral pneumonia, but vaccines such as the influenza (flu) vaccine and the measles vaccine can help prevent some of the viral infections that can lead to pneumonia. It is important to practice good hygiene, get vaccinated, and seek medical attention if you develop symptoms of pneumonia.
The vaccine makes the body create memory cells.
Usually nothing. Antibiotics won't help it has to run its course.
Antibiotics fight bacterial infections, antibiotics do not fight all bacterial infections however, they generally fight one of two types of bacteria (gram negative and gram positive). Antibiotics have no effect on viral infections or parasites, but they are sometimes prescribed with a viral infection to prevent a bacterial superinfection - when you get a bacterial infection because your immune system was weakened by the viral infection first. Antibiotics have saved more lives than those lost in any war but overusing them or not finishing a course can lead to the evolution of resistant bacteria which can no longer be killed by antibiotics.
Vaccines are for preventing infections. Infections are pathogenic (caused by germs). Vaccines help your body prepare to fight specific pathogens, e.g., bacteria and viruses.

Antibiotics treat bacterial infections, they have no affect on viruses. Vaccinations treat viruses.

An anti-viral medication is one that works against an infection by a virus. An anti-viral program is a computer program that works to detect and block or remove a computer virus.
The immune system produces memory cells, specifically memory B cells and memory T cells, to help fight future infections with the same type of virus introduced in a vaccine. These memory cells are able to recognize the virus quickly upon re-exposure and mount a faster and more effective immune response, providing immunity against the virus.
Interferons are substances produced by virus-infected cells that help neighboring cells fight viral infections. They trigger the immune response in nearby uninfected cells, stimulating them to produce antiviral proteins to combat the infection and prevent further spread of the virus.
Simply because there really isn't medicine to fight most viral infections. There are a few exceptions like tamiflu for flu, but most viruses cannot be fought with medication. Any medication prescribed would just help symptoms of the infection but not do anything to fight it off.
