How long do viruses live?
Which virus? The avian flu virus has a 4-5 day lifespan in the air and can travel 2-3km but is higly susceptible to disinfectants containing detergents.But which virus are you talking about?
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.
Lipophilic viruses require the lipid (fatty) envelope to remain active ("live"*), and the fatty layer can be destroyed by alcohol. Non-lipophilic viruses do not require this fatty envelope, and the protein layer (capsid) is more resistant to alcohol. *Note: viruses are not actually alive, they are only genetic codes with 1 or 2 (lipophilic) protective layers. Biologists call "live" viruses *active* and "dead" viruses *inactive* or *inactivated*.
The length of time that cold or flu germs can survive outside the body on an environmental surface, such as a doorknob, varies greatly. But the suspected range is from a few seconds to 48 hours - depending on the specific virus and the type of surface. Flu viruses tend to live longer on surfaces than cold viruses do. Also, it's generally believed that cold and flu viruses live longer on nonporous surfaces - such…

Usually your immune system will kill the virus and you will live your normal life span. There are specific groups of people who are at higher risk for complications and even death from the H1N1/09 flu, but the death rate is very low compared to even the seasonal flu viruses, chances are you will live as long as you would have without having had the flu.
Maurice Hilleman developed the first effective mumps vaccine in 1963. It was tested and became commercially available in 1967. It was created from live mumps viruses. Before that, starting in 1950, there had been a vaccine made from killed mumps viruses but it was not very effective or long-lasting.
In the US there is a flu vaccination made with live viruses that have been weakened (attenuated) to prevent them from making otherwise healthy people sick. This type of vaccine can be used by those who are healthy and aged 2 - 49. It creates a very good immune response to cause immunity and so it can be administered in an intranasal mist that is inhaled into the nose instead of having to be given…
Many bacteria live in your body, and most of them do not make you sick. The ones that do make you sick do so because of the fact that they use your body's resources to live and reproduce, and also because their waste products are toxic. Similarly with viruses - viruses reproduce by invading and reprogramming your body's cells to make more viruses. This harms your body because it destroys its cells.
