What is the condition in which antibodies protect a person from disease?
Antibodies protect people from disease because they are special defenders designed to fight a particular virus. Vaccines introduce small amounts of the virus into the body so it can build up antibodies against the disease.
What is Preparation and standardization of vaccines and immunization?
IT is prepared by weakening or killing a germ of that disease which is not strong enough to cause a disease. vaccines are given through a needle. these causes antibodies in the body's immune system which protect the body from diseases.
What is it that your body produces in response to vaccines to protect you against viruses?
Antibodies.As antibodies are produced, the body keeps a "record" of them and you will have developed an immunity to that specific virus in people with an otherwise healthy immune system. See more information below on how the immune system works.
Why do you need vaccines?
We need vaccines to protect us from infectious diseases and to trigger the immune system to respond with production of antibodies made for that specific pathogen. See the related questions for more details of how this works.
Explain how vaccines help in combating diseases?
Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system. Antibodies are proteins produced by the body to neutralize or destroy toxins or disease-carrying organisms. Antibodies are disease-specific. For example, measles antibody will protect a person who is exposed to measles disease, but will have no effect if he or she is exposed to mumps. There are two types of immunity: active and passive. Active Immunity Active immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Exposure to the disease organism can occur through infection with the actual disease (resulting in natural immunity), or introduction of a killed or weakened form of the disease organism through vaccination (vaccine-induced immunity). Either way, if an immune person comes into contact with that disease in the future, their immune system will recognize it and immediately produce the antibodies needed to fight it. Active immunity is long-lasting, and sometimes life-long.
Do vaccine cure or prevent disease?
Vaccines prevent disease by stimulating the immune system to produce protective antibodies against specific infections. While vaccines do not necessarily cure diseases once they are already contracted, they can help the body fight off the infection more effectively.
What are proteins that are made by cells to help destroy disease causing bacteria and viruses?
Antibodies are proteins produced by cells to target and destroy disease-causing bacteria and viruses in the body. They work by recognizing specific foreign invaders and signaling the immune system to attack and eliminate them.
How is a vaccine against a disease-causing virus produced using DNA technology?
Well all vaccines are made from weakened viruses so your body can defeat and remember them( T-Memory Cells). Small pox and polio vaccines are some of the most prominently and wide-spread, effectively elliminating the disease from much of America. However, it does still persist with occasional infections.
What is positive antibodies?
Positive antibodies indicate that the immune system has produced antibodies in response to a specific infection or vaccination. These antibodies help protect the body against future encounters with the same pathogen by recognizing and neutralizing it.
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.
Why is it difficult to find an effective vaccines against disease cause by pathogens that evolve rapidly explain why?
It can be difficult because when the disease evolves your antibodies will not fit the pathogens and you cannot simply have a different vaccine every week as it would be dangerous to your health.
What is the resistance from an organism to disease is know as what?
Immunity.Depending on how an organism becomes immune to an INFECTIOUS disease, classifies the immunity into :Active/ PassiveNatural/ ArtificialActive immunity- the organism produced its own antibodies to the disease.Passive immunity- the organism was given antibodies to fight the disease (this type does not last.. so that if the organism is re-infected with the SAME disease...it is not resistant like previously)Natural immunity- the organism naturally was infected to develop active immunity or given antibodies (from mother's milk).Artificial- the organism was deliberately infected to develop active immunity or given extracted antibodies (probably produced from rat's spleen).
