Confusing question. Essentially, one way your body recognizes viruses by the antibodies it left behind the last time you were infected. Another is the sheer presence of something "different."
Antibodies (immunoglobulin) are Y-shaped proteins that are produced by plasma cells, and which have millions of variable. At each tip of the "Y" is an antigen binding site (paratope), in essence a lock. When your body comes into contact with a foreign pathogen or substance, the antibodies (epitopes) of the invader trigger the immune system to produce antibodies. the antibodies with paratopes that correspond to the epitopes of the invader are attached, and the invader is neutralized or killed.
The problem occurs when your body does notrecognize a virus or some other invader. At these times your body has no or reduced defense against the pathogen, and in serious cases (bubonic and pneumonic plagues, dengue and hemorrhagic fevers, ebola, haunta, super flues such as H1N1 or Swine Flu, and SARS) the immune system cannot fight it and becomes overrun.
Any invasion of the body by a foreign substance or pathogen automatically triggers an immune response. In very simple terms, the body produces what are called cytokines. Cytokine are cell-signalling proteins, peptides, and glycoproteins and are molecules that message the presence of any substance or pathogen they see as an invader. Cytokines are one of the first steps in the innate immune system, and can trigger the production of other cells, biochemicals, hormones, and other immunological responses that attack and work to remove the threat. How they mark and target invaders and initiate production of the various types of immunological response is still not very well known.

How do body's defenders recognize an enemy?
I'm not sure what you mean by body defenders but T-cells are the ones that recognize the enemy. The white cells get that and they kill the virus, bacteria, etc.
How does the human body detect the Nipah Virus?
The human body detects the Nipah virus through the immune system's response to the virus entering the body. Once the virus breaches the body's defenses, the immune system produces antibodies to fight the infection and trigger an inflammatory response. This process helps the body recognize and eradicate the Nipah virus.
Explain how a vaccine is used to strengthen the body's natural immune system against a virus?
A vaccine introduces a harmless part or a weakened form of a virus into the body, prompting the immune system to recognize it as a threat. This exposure stimulates the production of specific antibodies and activates immune cells, preparing the body to respond effectively if it encounters the actual virus in the future. By "training" the immune system in this way, vaccines enhance its ability to recognize and combat the virus more efficiently, thereby providing immunity.
How can your body produce antibodies against dead viruses?
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.
How is the body's reaction to a vaccine similar to its reaction when it is attacked by a virus?
When vaccinated, the body produces an immune response similar to when it is attacked by a virus. This includes producing antibodies to fight the vaccine components. The immune system "learns" to recognize the virus in the future, allowing for a faster and more effective response if exposed to the real virus.
How does a flu vaccine work to protect against the influenza virus?
A flu vaccine works by stimulating the body's immune system to produce antibodies that can recognize and fight off the influenza virus. When a person is vaccinated, their immune system is trained to recognize the virus and respond quickly if they are exposed to it in the future, helping to prevent infection or reduce the severity of symptoms.
Why does getting an inoculation prevent measles?
The inoculation introduces a 'dead' version of the virus to the body. It is dead so there is no illness from having the needle. So when the real virus shows up, the body recognizes it and already has a defence against it.
How can a vaccine affect a viruses reproduction?
When you receive a vaccine, it puts a "dead" version of a virus into your body; it is one that cannot reproduce, but instead causes your body to produce anti-bodies that fight infection. When you come into contact with that virus, you already have anti-bodies to fight the virus in question. In the event that you ALREADY have the virus, do not receive the vaccine. It is not going to properly do its job. So, to give a more direct answer, it doesn't effect reproduction, it simply gives your body a warning that it might show up so that it is prepared.
Which part of a virus to White blood cells lock onto?
White blood cells can recognize viruses by their surface proteins, known as antigens. When a virus enters the body, white blood cells can lock onto these antigens to launch an immune response and target the virus for destruction.
What the basic mechanism of vaccine?
To allow your immune system to recognize the modified virus to prevent yourself from getting the virus yourself
How does a vacine work?
Vaccines work by injecting you with a small dose of either a weak or dead form of a virus/disease. Your body naturally tries to kill the virus by creating anti-bodies. Your body remembers how to create these antibodies so that when the real virus attacks, it can fight back killing the disease before it does any harm.
What is a deactivated virus?
A deactivated virus, also known as an inactivated virus, is a virus that has been rendered non-infectious through physical or chemical means, such as heat or formaldehyde treatment. These viruses can no longer replicate or cause disease, making them useful in vaccines to stimulate an immune response without the risk of infection. By introducing a deactivated virus into the body, the immune system learns to recognize and fight the actual virus if encountered in the future.
