American scientists have claimed that a flu vaccine is underway its development process that would immune one against all strains of flu.

The vaccine is being invented by a crew of scientists at the National Institute of Health in Maryland. As per researchers, it would be effective enough to build immunization against all strains of the disease including seasonal flu and flu outbreaks like swine flu.

It would take five years for the one-shot drug to come in the market. It would just require one or two shots of the vaccine to fight against strains of flu for the lifetime.

The drug is being made from DNA that when will injected into a person's body, will stimulate the immune system to generate antibodies against the protein's base, rather than the lollipop stick. The stick doesn't show much variation among different strains, so one vaccine would be enough to fight against all flu strains.

The trial of the drug has been performed on animals. Gary Nabel, the institute's Director of vaccine research derived DNA from the protein and injected into animal's body that kindled their immune system to release antibodies and wipe out the virus. Then, the common flu vaccine was used on the Animals, which could only destroy a flu virus from 2007 and one from 1934.
