What else can I help you with?
Vaccines can now be genetically engineered by inserting the genes that encode the pathogen's surface proteins into the?
DNA of harmless bacteria or viruses.
What is the use of genetically engineered bacteria?
The can produce antigens useful in making vaccines without the harmful parts of the original disease organism.
What is the role that microorganisms play in vaccine production?
Microorganisms are used in vaccine production to grow the viruses or bacteria that will be used as the basis for the vaccine. They are also used in the process of creating antigens or proteins that mimic the pathogens in order to stimulate an immune response. Additionally, microorganisms are sometimes used to test the safety and efficacy of vaccines during the production process.
What are edible vaccines?
Edible vaccines are vaccines produced in plants genetically modified through bioengineering.
Vaccines are effective in preventing disease because they?
Vaccines are for the purpose of disease prevention. Vaccination is the process of introducing harmless pathogens to the body for a response trigger without an actual infection. Vaccines are either composed of: *dead pathogens *weakened pathogens *protiens from the target pathogens
Explain why the development of genetically engineered proteins has been important to pharmaceutical companies?
Genetically engineered proteins are important to many areas of human life such as agriculture, research, medicine and industry. Research is especially necessary for the possible cure of diseases that threaten every culture on Earth. Pharmaceutical companies can utilize the insulin and vaccines so necessary in developing countries.
Are made using weakened pathogens?
Vaccines.
What is biopharming?
Biopharming is the method of using genetically modified plants, animals, or microorganisms to produce pharmaceuticals, vaccines, enzymes, or other high-value proteins. These genetically engineered organisms are used as "bioreactors" to produce biologically active substances that can be harvested for medical or industrial purposes. Biopharming has the potential to create cost-effective and sustainable methods of producing important drugs and therapies.
What are Weak pathogens injected into your blood called?
Some vaccines are really just a weakened form of the disease. These are called attenuated vaccines.
Do vaccines destroy viruses only?
Vaccines do not destroy pathogens, they give the immune system antibodies so it can destroy a pathogen before it causes an infection. Vaccines do exist for some bacterial infections.
Definition of the conventional vaccines?
Conventional vaccines consist of whole pathogenic organisms, which may either be killed or live vaccines; the virulence of pathogens is greatly reduced in attenuated vaccines. This is classified into 2 categories :a)Live or attenuated vaccines; (eg : BCG vaccine)b)Inactivated vaccines (eg : Salk polio & Pertussisvaccines)
What are the uses of vaccines?
a preparation of direct manipulation of genes of weakened or killed pathogen, such as a bacterium or virus that upon administration stimulates antibody production or cellular immunity against the pathogen but is incapable of causing severe infection.
