A virus doesn't have to be alive for the body to produce antibodies against it. Antibodies recognize the physical appearance of a virus. By using dead viruses the immune system is taught to look out for a live virus with the same characteristics of the dead one, but you don't risk being infected by the virus.

What does the body make to fight viruses?
Body has got immune system. This immune system or the body immunity forms the antibodies to fight the viruses. The immunity against the viruses is usually life long.
How has the measles vaccine prevented diesease?
Measles vaccine prevents from measles and is administered to children of 18 months with a second dose before age of 4 or 5 years. Vaccine of measles contain alive viruses (called antigens). The alive antigen can reproduce inside the human body but they do not damage host because they are weakened in laboratory to the point where they are still alive and able to reproduce but can not cause serious illness. When this vaccine is injected into the human body, the T cells of lymphocytes (White blood cells) detect the type of viruses in it. Then B cells of lymphocytes produce antibodies against these viruses. The viruses reproduce inside human body therefore the lymphocytes produce more antibodies against this specific type of viruses. Antibodies bind to the viruses, stop their activity and destroy them. Now the viruses of vaccine have been destroyed but the antibodies against them are still present and they prevent the actual viruses (harmful) of measles to cause illness. The person who has once caught measles also has the antibodies against measles viruses after the actual viruses entered the body and caused illness. Therefore the patient will recover within a week without using the vaccine.This person can not get measles again in life because the antibodies against measeles are already produced for prevntion by catching measles once. These antibodies are memory cell for this specific type of viruses. The vaccine of measles does not cure but it is used for prevention because it helps in production of antibodies against measles without causing illness.
Can you get a paragraph on how the measles vaccine help peoples life?

Why won't the antibodies for measles work against chickenpox?
Antibodies for measles don't work against chickenpox virus because antibody for measles virus can not bind to chickenpox virus. Antibody for a specific antigen should have a shape and structure that is able to fit into this virus. Then it will be able to inhibit the activity of this virus. When a measles vaccine is inserted inside human body, or when someone has measles, the T type lymphocytes (White Blood Cells) detect the type of viruses and then B type lymphocytes produce the antibodies against this specific type of virus. If viruses of the vaccine are alive they will reproduce themselves inside the human body and the number of antibodies against them also increases. Antibodies bind to these viruses and destroy them. Now the virus (of specific disease which needs prevention) which was in the vaccine have been destroyed but the antibodies against this disease viruses are still there and they prevent from the actual disease causing viruses. Antibodies are specific: An infection with the measles virus means that the person makes antibodies only against measles. It doesn't make any antibodies against chickenpox too.
What is the job of white blood cell?
To produce antibodies, engulf antigens and produce antitoxin. They do this to protect the body of disease-causing bacteria and viruses.
What stimulates a person's body to produce chemicals that destroy vireses or bacteria?
The best answer would be Antibodies; however, these do not chemically "attack" viruses or bacteria. More accurately, antibodies recognize various germs and allow the various cell types of your immune system to attack and destroy these germs directly. For more info on how this works see: http://en.wikipedia.org/wiki/Adaptive_immune_system
What does the human immune system produce that is the basis immunization?
Antibodies
What all does our body's fight viruses with?
antibodies
What do white blood cells produce to fight viruses inside the body?
Antibodies. which you know is a white blood cell that fights things that are anti-body.
How does the MMR vaccine work?
The MMR Vaccine contains tiny doses of living but inactivated viruses that cause measles, mumps and rubella. Once these viruses are injected into the body, the immune system will develop certain antibodies against these three diseases shortly following vaccination. Because your body has memory cells it now knows how to defeat these diseases when they enter the body again, and it will know which certain antibodies it needs to produce; these antibodies in your body will give a lifelong protection against these diseases.
What role do antigens normally play in the human body?
are antigen apart of the body's natural defense against infections
Why doesnt the measles vaccine protect you from all of these disease?
AnswerBecause it does not help in production of the antibodies against other diseases inside the human body.ExplanationMeasles vaccine contain measles viruses (alive) called antigen. The measles virus inside it are alive but do not cause this disease because they are weakened in laboratory to the point where they are still alive and able to reproduce but do not cause serious illness.When this vaccine is inserted inside human body, the T type lymphocytes (White Blood Cells) detect the type of vaccine viruses (measles) and then B type lymphocytes produce the antibodies against measles viruses.The measles viruses of vaccine are alive so they reproduce themselves inside the human body and the number of antibodies against them also increases. Antibodies bind to these viruses and destroy them. Now the measles viruses of vaccine have been destroyed but the antibodies against the measles viruses are still there and they prevent from the actual measles viruses.These antibodies can not prevent from other virus because every virus has different structure so different antibodies are needed to destroy it. Antibody for a specific antigen should have a shape and structure that is able to fit into this pathogen.Then it will be able to inhibit the activity of this pathogen.So the other diseases are prevented by other vaccine having the viruses of this disease which help the production of antibodies against this specific disease.The viruses of vaccines may be killed or alive.
