The process of vaccination?
Vaccination is the process of attempting to confer artificial immunity on an individual organism by exposing the immune system to antigens of the pathogen being vaccinated against. Vaccination does not provide nearly as good protection as natural, or acquired immunity.
What is the relationship between immunity and vaccination?
You get immunity by having a vaccination or by having the infection itself. The vaccination is the introduction of the pathogen in tiny amounts to kick start your immune system so it knows how to deal with the real thing if you encounter the germ in the environment. A vaccine is the medicine made to introduce the pathogen (infection-causing "bug") into your body in a vaccination. Having immunity is how your body prevents a second infection by the same germ. The first time you catch the germ (or get a vaccination for it), your body responds to cause immunity, so if you run across the same exact germ again later, your body already knows how to prevent an infection again. See the related questions below for more about vaccines and vaccinations.
What makes immune deficiency disorder so dangerous?
It sounds like this is schoolwork for someone somewhere...without an immune system, our bodies are left undefended against foreign invaders. The first opportunistic pathogen (this could be a virus, a bacterium, a fungus, or a parasite) to infect an individual without an immune system will likely result in this person's death. That is, someone without an immune system (the body's defense against infection), a person cannot live unless they are completely isolated from any source of infection.
What is the role of memory cells in providing acquired immunity?
The idea of immunisation is that you expose the immune system to the pathogen, ennabling it to recognise the pathogen and produce mature memory Helper T cells. This means that upon its second exposure the immune system is activated faster and more efficiently, allowing the immune system to kill off the pathogen quicker. In some cases antibodies are produced that can neutralise toxins, preventing their damaging effects. If memory T cells were not produced then the immune system would have to re-learn how to fight a pathogen every time.
What is the meaning of passive immunity?
Our immune systems are designed to keep track of the various infections that can be caused by pathogens once they encounter them. This helps to increase our immunity as this information helps the bodies immune system to fortify itself against further attacks by the same pathogen. If immunity is increased by means other than acquiring the disease, then it is known as passive immunity. e.g. Vaccination( in this weak pathogens are injected in the body and this helps the body's immune system to remember and then identify it to fortify the body for any future attacks by that pathogen)
How many times will a person get the actual disease if vaccinated?
Ideally a person would never contract a disease that he/she has been vaccinated against. The foundation of vaccination is the idea that you expose a person's immune system to the pathogen that causes a disease so that the immune system will recognize it and kill it off quickly if the person is ever exposed again. In reality, some vaccinations just don't work - there are always a few people that don't respond to the vaccine, or that respond weakly and don't have enough memory cells to fight off the pathogen.
Why are babies vaccinated?
Babies are vaccinated to protect against common diseases until their immune systems are developed.
What is immune response?
An immune response is part of the body's defense against pathogens in which cells of the immune system react to each kind of pathogen with a defense targeted specifically toward that pathogen.
The process of vaccination?
Vaccination is the process of attempting to confer artificial immunity on an individual organism by exposing the immune system to antigens of the pathogen being vaccinated against. Vaccination does not provide nearly as good protection as natural, or acquired immunity.
Does use of a vaccine to stimulate the immune system to act against a pathogen?
Yes.
What in a vaccine makes the immune system respond?
A dead or very weak form of the disease.
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.
True or false Vaccination triggers an immune response against the pathogen by simulating an infection?
True
One characteristic of the immune response is specificity This means that?
Immunity is directed against a particular pathogen.
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.
What happens when a pathogen enters in our body second and subsequent times?
During subsequent exposures to the same pathogen, the immune system is able to respond rapidly and activity reaches higher levels. The secondary immune responses can usually prevent disease, because the pathogen is detected, attacked and destroyed before symptoms appear.
Why does a vaccination provide long-lasting protection against a disease while gamma globulin provides only short-term protection?
With vaccination your body mounts an immune response to the pathogen. You learn what the pathogen looks like and make antibodies (gamma globulin) against it. You then get memory cells which can last a very long time and will let your body respond and fight off the pathogen the next time you are exposed. Gamma globulin is just an antibody that will circulate in your blood and and fight off the pathogens it was made against. You will not mount an immune response, and you will not get memory cells for long lasting protection.
