Flu Shot (Overview)

Also known as influenza vaccines, flu shots are given out once a year to protect against the flu. The flu shot stimulates the immune system to build antibodies to three or four strains of flu viruses in the hopes that it will offer protection from the current strains present in the community. Each year the Centers for Disease Control (CDC) monitors the strains of Influenza globally and incorporates the appropriate antigens in the new vaccine. For best protection the vaccine should be acquired annually.

How do flu shots work?

How do flu shots work?

They create memory: Flu-shots have parts of the virus that can't cause infection, but provoke an immune response. The virus continually changes, so that protection requires a new vaccine containing parts of the correct strain(s) of virus circulating that year, as predicted by the who. The immune reponse leads to "t-cells" that remember that part of the virus, and can quickly fight off live virus when you get exposed. ...Read more

What exactly makes up a flu shot vaccine?

What exactly makes up a flu shot vaccine?

Not live...: The flu vaccine does not have any live flu virus. Rather, it consists of killed virus or protein from the virus. Your immune system then reacts against the virus protein and makes antibodies so that if your body then is exposed to the actual virus, the antibodies needed to kill it are already there. This prevents you from getting sick from the virus since the antibodies kill it first! ...Read more
