influenza virus, and is controlled by vaccines in the arm using a
syringe and a needle. The dead virus activates the immune system of the
body which produces specific antibodies for protection against the
virus. The seasonal flu shot contains virus that are commonly found in a
particular season. This is the best way to prevent the flu,
and flu prevention should be a goal for everyone.

two weeks prior to the inception of the flu season, so that, by the time
the flu spreads across the surrounding, your body is prepared to fight
against the infection. It must also be remembered, that a flu shot is
effective only against the strains of virus incorporated in it. If a
person contracts a viral infection by a different virus, the flu shot
will remain ineffective.
