Flu Shot Effectiveness?

You might recall last year’s flu shot had some challenges–including a virus that mutated after the vaccine was formulated, then a further mutation later in the season. The CDC has added three times the protection for this year’s flu shot.

This year there are two different types of flu shot. The trivalent vaccine protects you against the A/H3N2, A/H1N1, & influenza B strains via a traditional shot, intradermal shot, or high dose shot for people over 65. The quadrivalent vaccine protects you from A/H3N2, A/H1N1, and two types of influenza B via traditional flu shot and nasal spray (not approved for pregnant women.)

There are two factors that determine how effective the flu vaccine will be. One, the match between the flu virus and the flu vaccine. Second, age and overall health of the person being vaccinated. By getting the flu vaccine, you are 60% less likely to need medical care for the flu.

It is important to be vaccinated early in the Fall before flu season begins, because it takes approximately two weeks for your body to develop the antibodies that defend against the flu virus. Remember getting the flu shot is your best chance of preventing the flu virus. Once you receive the flu shot, you will be protected for the whole flu season and will not need another vaccine until next year.

Why wait? Find a flu shot administrator nearby and keep you and your loved ones healthy this flu season.
