The measles virus finds a healthy cell and high-jacks it to create more viruses.
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.
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.
Host tissue refers to the cells, tissues, or organisms that provide the environment for a parasite or pathogen to live and reproduce. It can be human, animal, or plant cells that are susceptible to infection or infestation by a foreign organism.
Human pathogen.
When the human body mobilizes its defenses against a pathogen, it recognizes the pathogen by identifying specific molecules on its surface called antigens. The immune system then mounts a response by producing antibodies that target and neutralize the pathogen, as well as activating immune cells to attack and destroy the pathogen. This orchestrated immune response is crucial for fighting off infections and maintaining health.

Host tissue refers to the cells, tissues, or organisms that provide the environment for a parasite or pathogen to live and reproduce. It can be human, animal, or plant cells that are susceptible to infection or infestation by a foreign organism.
An animal, insect, or human whose body can sustain the growth of a pathogen is known as the pathogen's host.
Human Pathogen
pathogen/host
Viruses, bacteria, protists, and parasitic worms.
No, Vibrio cholerae is primarily a human pathogen.
HPV stands for human papillomavirus. HPV is a virus.
Infection allows the pathogen to enter human cells. Without infection plasmodium or any other pathogen can not enter the cells.
