What does immune mean?

Answer 1

If you are imune, then your body has made anti-bodies for a certain virus/disease. Once your body has made the antibodies the next time your body comes across that virus/disease, your body will be IMMUNE to it, and will know how to defend itself.

If you have injections to prevent a particular virus/disease, then they will inject dead or un-active microbes of that virus/disease. Because then, without doing your body any harm, your body can make antibodies, making you immune.

Answer 2

Prior to the vaccination, the body's white blood cells will be unable to use their existing antibodies. This is because the body's defence is not able to recognise the invading virus and will take too long to create an antibody to help destroy the virus. After the vaccination, which contains a harmless sample of the disease, the body will be able to fight this small amount of the disease in its own time; the white blood cells now have that disease locked firmly in its "mind". This process is called "immunisation". I am 13 and I think I have successfully beaten you.

Answer 3

Immunization is the ability of your body to eradicate a malicious "invader" in the body. By having immunization to a virus or disease, your body already contains the memory cells or the virus fighters to immediately destroy the virus without it taking hold of your body and making you sick. Their are also two types of immunity. Passive immunity happens if you actually have the disease and your body has already conquered the virus (for example, the virus can't pull the same trick twice such as in chicken pox which you get only once). The other type is active immunity, which occurs if a oerson receives the antidote to the virus from the mother- either in the uterus or through breast-feeding- or through injection. Doctors can inject the vaccine for a virus or disease giving you immunity against that illness.
