Inside The Syringe: How The Flu Shot Works


And I kind of pinch here
and I’m gonna poke ya. It only takes a few seconds to get,
but it can end up saving your life. All done. The flu shot packs quite
a punch. So, how does it work? Over at the Washoe County Health District, public health nurse Lynnie Shore explains
the magic ingredient that vaccine manufacturers put in those syringes. Killed viruses. They take a small amount
of the virus, they kill it, treat it, but there’s still enough there that it
generates an immune response from your body so that when you are
infected with influenza, it attacks it and helps get rid of it. The vaccine reduces your risk of
contracting the flu by 40 to 60%, according to the Centers for
Disease Control and Prevention. While the vaccine doesn’t
provide guaranteed immunity, it still cannot give you the flu,
contrary to a popular misconception. Shore explains why some people
still hold on to that age-old myth. Once you get the flu shot, it takes your body up to two weeks
to develop the antibody protection. So right now we’ve had flu circulating
since October in our community, and the chances are that you may have
already been exposed to the disease and you’ve gotten the shot and certainly
you’re going to think that the shot gave you the flu when actually you were exposed
to it or you weren’t fully protected by the time the vaccine kicked in. Over at the University of Nevada,
Reno, Student Health Center, Dr. Cheryl Hug-English explains why people
need to get the flu shot every single year, as opposed to most other
vaccines that last much longer. The one thing about the flu is that
it is a sneaky virus that mutates very quickly each year, and so every year
the strain is a little bit different. And the vaccine, it’s a little bit
of a guessing game. Some years, the vaccine is more effective than others
because they predicted the strain of the flu virus a little
bit more successfully. And Band-Aid…And you did a great job. Thanks. Yeah. Of course.
