3.the body will be able to fight invasion by the same type of microbe in the future
they cause specific responses in specific cells.
Pathogens are made harmless for vaccines through processes such as inactivation (using chemicals or heat to kill the pathogen), attenuation (weakening the pathogen's ability to cause disease), or using only specific parts of the pathogen (such as proteins) that stimulate an immune response without causing illness. This allows the immune system to recognize and remember the pathogen, providing protection if exposed to the real pathogen in the future.
A vaccine stimulates the body to produce antibodies against a specific disease causing pathogen. This makes the body able to fight off that disease.
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.
each pathogen has a antigene which the antibodies attach to so each pathogen needs a unique antibodie
N/aA pathogen by definition is a disease causing organism
The purpose of introducing weakened microbes or pathogens into the body for vaccination is to stimulate the immune system to recognize and respond to the pathogen without causing disease. This exposure helps the body develop a memory of the pathogen, allowing it to mount a quicker and more effective immune response if exposed to the actual pathogen in the future. This process enhances the body's ability to prevent infections and provides long-lasting immunity against specific diseases.
You'd most likely want to expose yourself to a "dead" version of that pathogen via vaccination.
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.
That is the job of the B-cells, or B Lymphocytes.
it causes other diseases
Antibodies attach to specific antigens on the surface of pathogens.
