A flu question,?

hello

this happened a while ago but I'd thought I'd ask anyway. I got a flu vaccine about three months ago along with a few other vaccine. Inronically about one week after it I ended up getting the flu anyway. I guess my question is, are there many different types of flu? or might it have something to do with the vaccine? I guess I'm looking for a possible explanation, mainly curious more than anything else.

Flu vaccines only protect you from the three strains that were the most dangerous from the year before. They are called "trivalent" vaccines - 3 virus antibodies bonded together in one vaccine.

These vaccines do not contain a live virus, so they cannot infect you. However, while they do kick up your immune system, it takes at least a couple of weeks to achieve immunity. If you are exposed to the flu bug before you have made adequate antibodies, you can still get sick.

Thats normal cause u were injected the flu virus, weird right?

Flu is caused by a virus known as influenza virus. This virus can change its outer covering wall (antigen) against which your immunity stimulated by the vaccine is supposed to work. This change in the outer coating of the virus wall occurs in periodical cycles. This is one way the virus manages to hood wink your body's immunity.

A vaccine is when they acually inject you with a mild form of the disease/virus you are trying to prevent. You probably just got a mild case of the flu, which is much better than some of the strains you were protected from. Now your body knows how to fight the flu and will recognize it if you are exposed to it from now on. Kind of like chicken pox, once you get it, it rarely comes back!
