How does being injected with a inactive form of pathogen make you immune to the disease?
The inactive form of the pathogen still has the antigens (protein markers) specific to that pathogen on their surface. Antibodies locate the pathogen and create the correct form of antibody to combat it. As it is inactive the person does not suffer the effects of this pathogen, but when an active form is encountered later the immune system is quicker to respond due to the fact that it now recognises those antigens.

How does injecting an inactive form of pathogen make a person immune?
the inactive form still has the antigens (protein markers) specific to that pathogen on the surface. the immune system develops specific responses to this pathogen when it is encountered after a vaccination. as it is inactive the person does not suffer the effects of this pathogen, but when an active form is encountered later the immune system is quicker to respond due to the fact that it now recognises those antigens.
What is the name of the process when a person is immunised against a disease by injecting them with an inactive form of a pathogen?
The process is called vaccination. It involves injecting a person with a harmless form of a pathogen, such as a dead or weakened virus or bacteria, to stimulate the immune system to produce an immune response without causing the disease.
Do the injected microorganisms have the same antigens as the live pathogen?
The injected microorganisms in a vaccine may have the same antigens as the live pathogen, but they are weakened or killed to prevent disease. This allows the immune system to recognize and build immunity against these antigens without causing illness.
What must a vaccination contain to make it effective in producing immunity?
A vaccination must contain either a weakened or inactivated form of the disease-causing pathogen, or specific pieces of the pathogen such as proteins or genetic material. This prompts the body's immune system to recognize and remember the pathogen, allowing it to quickly mount a response if the person is exposed to the actual pathogen in the future.
How do vacines work?
Vaccines work by exposing the immune system to a weakened or inactive form of a specific pathogen, stimulating the production of antibodies. These antibodies recognize and attack the pathogen if the individual is later exposed to the same disease, preventing infection or reducing its severity. This leads to the development of immunity against the disease without causing illness.
What is a true pathogen and an opportunistic pathogen?
True Pathogen- are capable of causing disease in healthy persons with normal immune defenses ex. influenza virus, plague bacillus, and ect Opportunistic pathogen- cause disease when the host's defenses are compromised or when they grow in part of the body that is not natural to them
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.
In what two ways can a person become immune to an infectious disease?
A person can become immune to an infectious disease through vaccination, which triggers the body's immune response to produce antibodies against the pathogen. Additionally, a person can also develop natural immunity by recovering from an infection, where the immune system creates memory cells that can recognize and fight the pathogen if re-exposed.
How does a pathogen cause disease in the human body?
A pathogen causes disease in the human body by invading and damaging healthy cells, releasing toxins, and triggering an immune response that can lead to inflammation and tissue damage.
Does active immunity involve a person becoming immune to a pathogen as a result of having a disease?
by vaccination
What is the name of the liquid which can protect you if given before you have the disease?
it is vaccine . you get injected it before and it makes ou immune to the disease.
Is a medicine that stimulates the body's immune response to make disease-fighting molecules to attack a specific pathogen?
antibiotics
