Viral infection can be prevented, but not cured, by vaccines.
No vaccine can 'cure' the cold. common cold usually recovers of it's own. It takes few days to recover. Any vaccine is useful after few weeks, say three weeks for example.
Vaccine can prevent the flu.
Antibiotics only works against bacteria! Since Viruses are not living things, ( because they are single celled organisms) they can only be prevented and can never be "cured". To prevent from obtaining viruses, you get Vaccines (shots). Vaccines are weak or dead viruses injected into your body to release mass amounts of B cells that will help fight against the disease.
Vaccines don't kill viruses or diseases; they prevent disease before you are infected.

You can get cured after you have been sick
This is how vaccines help the body's natural defenses against viruses: -because vaccines contain weak and dead viruses -this can help our immune system to recognize and adapt to it -so this will not be the problem for it if later on this type of viruses threat us Hope this help Vipha
What are vaccines for influenza made from?parts or products of a virusdead, whole virusesantibodies to the virusweakened viruses
Vaccines for the prevention of the specific viral infection can be made with inactive "dead" viruses. They are also made with live, but attenuated (weakened), viruses. See more below about vaccines.
Currently, all vaccines on the market today only exist for diseases caused by viruses- though not all diseases caused by viruses have a corresponding vaccine. Notably, the common cold (rhinoviruses) and AIDS (HIV) have no vaccines.
Because certain viruses and bacteria evolve to become resistant to the old vaccines.
Vaccines are small amounts of live viruses injected into the body. These viruses teach the body's immune system how to fight off the disease. Correction: Some viruses are live. Some are weakened, most flu vaccines are dead viruses, not live, although the nasal mist is a live, weakened virus. Please make sure your answers are correct.
