How does the yellow fever vaccine work?

Answer 1

Flu vaccines work to give a pattern of the strain of virus they are developed to combat to the body's immune system so it can create a way to disable the specific virus. It works on the principle that once a person has had and survived a virus infection, there is an immunity from the same virus making you ill in the future because the body knows just what to do to stop it the second time before it has any chance of making you sick.

To give the pattern to the immune system, vaccines are made two different ways, one is to use an inactivated form of the virus ("dead" virus) so it can not make you sick but your body will still recognize it as a foreign substance that has invaded your body and it will create the perfect "killer cells" for it. The other type of vaccine is made from active ("live") viruses and it does the same thing with your immune system, except it has been attenuated (weakened) so that it is not strong enough when it gets into your cells to make you sick.

Another answer:

The vaccine is made from the virus itself! You put the virus into you so your cells notice that it is bad! The cells will 'defeat' the vaccine (or virus), then if you may get the actual virus, the blood cells will know how to battle it and destroy it before it causes harm to your body!

Answer 2

The vaccine puts a weaker form of the virus (the arbovirus) into your body, and the white blood cells produce antibodies, antitoxins or perform faegocitosis quicker to destroy the virus and make you more immune to the disease as the virus wouldn't reproduce a lot.
