By Pure Matters Unfortunately, some people think that getting a
flu immunization is too much trouble or costs too much. Or, they
swear that a flu immunization will make them sick or make them
more likely to catch the flu--or even colds. Influenza--the flu
--is caused by one of several strains of influenza viruses (type
A or B) that infect the nose, throat and lungs, making life
miserable for a week or two for many people--and deadly for
some. Flu season can peak anywhere from late December to early
April, according to the CDC. Your best defense against the flu
is to get immunized. Depending on your age, you can do that in
one of two ways: - With a flu shot, given with a needle. This
form of the vaccine contains killed virus and is approved for
all people over the age of 6 months. - With a nasal-spray
vaccine. This form contains live, weakened flu viruses that
cannot cause the flu. This form is approved for healthy, non-
pregnant people ages 2 to 49 years. A flu vaccination is most
important for children 6 to 59
