Why doesnt the measles vaccine protect you from all of these disease?

Answer 1

Answer

Because it does not help in production of the antibodies against other diseases inside the human body.

Explanation

Measles 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.
