How does the immune system respond to develop immunity after being given the vaccine?


Question:


Answers:
The body produces two types of antibodies. The first is designed to attack an antigen that has entered the body, to keep it from multiplying. This first type is stored in the lymph system throughout the body, and is assigned to attack antigens as they appear.

The second type of antibody, the one you are concerned with, is formed to attack a specific microorganism. When a vaccine is administered into the body, it is a weakened or dead form of microorganism, which the body produces antibodies against. These antibodies remain in the body in great enough numbers to ward off infection from that microorganism, in many cases, for the remainder of your life. The second type of antibody would only serve to protect the body from that microorganism for which it was originally formed ( the vaccination). Hope this helps some.

Other Answers:
This is what I understood on how it really works.

You see, the vaccine given is supposed to be dead virus causing a certain illness (like if you are immunized with measles, the vaccine is actually tons of dead measles virus.^_^).

Once the dead virus/vaccine is injected and released in the bloodstream, the immune system produces antibodies so that it could stop these viruses from supposedly "colonizing" (but it's dead anyway, so it won't really happen). It even is possible that in the process the dead virus could become a part of your body, it will be synthesized in such a way that it won't do your body any harm. That's why it's advisable that you get immunized more than once-so that your immune system will be more familiar with the virus.

So now, because your immune system is somehow prepared for that kind of virus, because you have given it "trainings" and "practice", when the real, living virus attacks, it already knows what to do.

Hope I was helping!!^_^
