a vaccine
Vaccine This is any solution that is prepared to cause immunity against a specific disease, usually employing a non-harmful form of the disease agent (the virus or bacteria), as killed or weakened (inactive) to stimulate antibody production.
Active immunity is of two kinds: Natural active immunity: This is acquired when a pathogen enters the body and immune response occurs. This is stored by the memory cells and eliminates the pathogen for the second time as soon as it enters the body. Acquired active immunity: This artificial and it is induced through a artificial source like vaccines.
Physicians prescribe drugs to the patients.But the pathogens have the propensity to evolve and become "super bugs"(so called because they are drug resistant).This could lead to a bad condition of the disease or might develop some rare form of disease.The common cause of the development of drug resistance is inappropriate dosage of drugs.In that case these drugs act as natural selection agents and could not kill the entire population of pathogens this could lead to the increase in frequency of those resistant forms of pathogens.So if a physican has a clear understanding of evolution by natural selection he will not be careless about the dosage of drugs
Cardiovascular disease is more commonly known as heart diseases. but one of the most common heart disease is coronary artery disease.
Viruses are not considered living organisms but can cause disease. Prions that cause Bovine Spongiform Encephalopathy (Mad Cow disease, aka vCJD- variant Creutzfeld-Jakob disease when in humans) are not living organisms as they are just misfolded protein particles.
You are giving the definition of a vaccine but not "what is the following to choose from"
medicine containing dead or weakened pathogens
Live vaccines contains weakened viruses of the disease. These viruses can not cause the disease but give immunity to the recipient. ( In the initial days of such trials, 18 patient got the rabies due to vaccine and died.)
Immunity.
That is called a vaccination.
Vaccin
a vaccine
weakened pathogens
The medical term for disease resistance is immunity.
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
These substances are called "vaccines".
