The flu vaccine is strongly recommended annually for everyone
beginning at 6 months of age. There is no upper age limit for
the flu vaccine. The older one is, the more important it is to
get immunized. However, there are some reasons for a few people
to avoid the flu vaccine, these include: —People with severe
allergies to eggs, such as anaphylaxis. Minor allergies to eggs,
such as hives or lightheadedness is not a contradiction, but the
vaccine should be given in the presence of a health care
provider familiar with and capable to responding to allergic
reactions. —Children under 6 months of age. —People who have
developed Guillian-Barre syndrome within 6 weeks of getting a
flu vaccine. —People with a moderate or severe illness should
wait until they recover. For a child with a mild temperature
elevation or a mild, probable virus; illness is not a
contradiction. The nasal spray flu vaccine is a live weakened or
attenuated flu virus and is approved only for non-pregnant
healthy persons aged 2-49 years.
