There have been many influenza epidemics. There are now two well-known pandemics (covers a much larger world-wide area than an epidemic or a smaller outbreak). The "Spanish Flu" pandemic was in 1918 and 50-70 million people died of the virus. The most recent pandemic was the H1N1/09 "Swine Flu" pandemic beginning in 2009 with some isolated cases still ongoing in 2012.
In 1931, viral growth in embryonated hens' eggs was discovered, and in the 1940s, the US Military developed the first approved inactivated vaccines for influenza, which were used in the Second World War. (Wikipedia)

Discovered in 1931 by Richard Shope.
Following his work, a British research team led by Patrick Laidlaw was able to isolate the virus from humans in 1933.

Many scientists believe that the big bang started life. The big bang was a big explosion and the galaxies began.
Some people believe in that theory, but some people believe in Adam and Eve. Scientists claim that they have found evidence that we started from apes.

There are scientists that believe in a god and there are scientists that don't. Surveys find that a large majority of scientists do not believe in a god and even fewer believe in a creation account of the world.
True scientists are not fool to believe in ghosts.
