What is a substance usually a protein that causes the formation of an antibody and reacts specifically with that antibody?
An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).
A vaccine can give you active immunity because it is a form of a specific?
(1 pt) antigen
Can a new unrelated peptide antigen can be used along with live vaccine to raise antibody against both?

What does the triple antigen vaccine prevent?
There are different kinds of triple antigen vaccines. A triple antigen vaccine is one made with three different antigens (often three virus strains). The seasonal flu vaccines are examples of triple antigen vaccines, because they contain vaccines against the three influenza viruses most prominent and most likely to spread that season. These are also called Triple Valent or Trivalent vaccines. Another example is the MMR trivalent vaccine made to vaccinate against Measles, Mumps, and Rubella. Several of the childhood vaccinations are this type of trivalent vaccine.
Why does a particular vaccine give immunity against one disease only?
That is a good question! In the vaccine, you have few proteins, that are derived from particular organism only. The antibodies are very specific. They act against the particular proteins only. So from the given vaccine, you get specific antibodies. Those antibodies will act against that particular organism only.
Why does a vaccine have to be a specially prepared version of a disease pathogen?
A vaccine is a special version of an antigen the gives you immunity against a disease. A vaccine is a weakened form of disease which helps your immune system create antibodies to fight it off so later if you ever get that certain disease again your body would recognize it and create antibodies to fight against it before it gets too serious.
How does a DNA vaccine prevent future disease?
A DNA vaccine contains DNA from a pathogen but cannot cause disease. When the vaccine is injected into a patient, the DNA directs the synthesis of a protein. Antibodies are produced by the body against the protein. If the patient contracts the disease in the future, the antibodies in his or her body will be able to provide protection.
What is vaccine production?
Vaccines are produced in large scale as they need to be administered to large populations of children and adults to be effective as a public health tool. This large scale production is often a challenge. Vaccine production has several stages. Process of vaccine manufacture has the following steps: Inactivation - This involves making of the antigen preparation Purification - The isolated antigen is purified Formulation - The purified antigen is combined with adjuvants, stabilizers and preservatives to form the final vaccine preparation.
Why can someone that's vaccinated against mumps still be infected by chickenpox?
The vaccine that is for mumps is not for any other pathogen. The vaccine is said to be specific. It can be said that the vaccine is like a pair of shoes that fits only you and not your father.
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.
Why a student vaccinated against mumps can still be infected by the pathogens that cause other diseases?
The vaccine that is for mumps is not for any other pathogen. The vaccine is said to be specific. It can be said that the vaccine is like a pair of shoes that fits only you and not your father.
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.
