What else can I help you with?
Can you get infected with diphtheria again?
Previous infection may not prevent against future infection.
A blood cell that fights disease?
White blood cells produce antibodies against a virus so you don't get it again.
How do antibodies protect your body against disease when exposed to a virus?
Each antibody is made to target certain antigens (disease or virus). They then would destroy them. The antibodies stay in the body so that if the antigen attacks again, the antibodies would already be there to destroy them.
Can antibodies be used up?
Antibodies are continuous being produced by activated B cells in your body as a response to your constant exposure to invaders. Antibodies are proteins and synthesized like proteins. Therefore, antibodies will be produced until you die. However, antibodies against a certain type of invaders may disappear when the invaders are eliminated. The ability of the body to respond to the same invaders when they come again lies in the preservation of the B cells that produced these antibodies, not the actual antibodies themselves.
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.
Can the same person hit the ball if the person hits the ball against the net again?
No, they can only hit it again after another person has touched it.
Why does the body need to produce many different kinds of antibodies?
By definition, antibodies act against particles, proteins, microbes, and viruses. Each antibody has to be a "match" or a "fit" to work against what it is working on. So if you have had chicken pox, you made antibodies to act against it and inactivate it. If you are exposed again, you will not get it. If you get a blood transfusion it must match or your antibodies will inactive it and will cause a reaction that will hurt you. Think of all the things you have come across: different pollen from different plants, different colds, different flu (you have to get a new shot every year as it is different), different vaccines. It just goes on and on.
What is the advantages and disadvantages of active and passive immunity?
Active Immunity -The body reacts by producing antibodies to fight the pathogen. The antibody levels in the blood will rise and the boy will also retain a memory of of how to make these antibodies if it comes across the pathogen again. This process provides long-term protection from many diseases.Passive Immunity -Advantage: gives immediate protection against the pathogen.Disadvantage : Immunity is short lived and if the person encounters the disease again at a later date, the body has no memory of developing antibodies itself. This type of vaccination is only used in a few cases to give quick protection when it is thought the person may already have the disease.
If a person recovers from H1N1 and again gets infected by H1N1 what are the chances of his survival?
Once someone has had a case of swine flu that is confirmed, then they will have lifetime immunity to the disease and not catch it again.
How has the measles vaccine prevented diesease?
Measles vaccine prevents from measles and is administered to children of 18 months with a second dose before age of 4 or 5 years. Vaccine of measles contain alive viruses (called antigens). The alive antigen can reproduce inside the human body but they do not damage host because they are weakened in laboratory to the point where they are still alive and able to reproduce but can not cause serious illness. When this vaccine is injected into the human body, the T cells of lymphocytes (White blood cells) detect the type of viruses in it. Then B cells of lymphocytes produce antibodies against these viruses. The viruses reproduce inside human body therefore the lymphocytes produce more antibodies against this specific type of viruses. Antibodies bind to the viruses, stop their activity and destroy them. Now the viruses of vaccine have been destroyed but the antibodies against them are still present and they prevent the actual viruses (harmful) of measles to cause illness. The person who has once caught measles also has the antibodies against measles viruses after the actual viruses entered the body and caused illness. Therefore the patient will recover within a week without using the vaccine.This person can not get measles again in life because the antibodies against measeles are already produced for prevntion by catching measles once. These antibodies are memory cell for this specific type of viruses. The vaccine of measles does not cure but it is used for prevention because it helps in production of antibodies against measles without causing illness.
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.
