Why do vaccines protect against a specific viral disease?
Question:
A. They don't - only antibiotics protect against viruses.
B. They remain in the body and attack the virus.
C. They stimulate the sweat glands to eliminate the virus from the body.
D. They stimulate the immune system to recognize and kill any virally infected cells the next time you're exposed to the disease.
Answers:
I select item No.D.
Item No.A- Antibiotics have no effect on viruses because they reside within the living cells.
Item No.B-Vaccines containing live, attenuated microorganisms - these are live micro-organisms that have been cultivated under conditions that disable their virulent properties.
Item No.C-The virus cannot be eliminated through the sweat glands.
Item No.D-They typically provoke more durable immunological responses and are the preferred type for healthy adults. Examples include yellow fever, measles, rubella, and mumps.
D of course
A vaccine for a virus is made from a dead or severely crippled virus. That virus or some of the parts of the virus are injected into you, and your body recognizes those parts as foreign. It then makes antibodies against those parts so the next time you see the virus, your body is already prepared to destroy it.
Answer would be D.
here is how vaccines work. vaccines are nothing but dead whole bacterial cells that are injected into the body. they cannot cause any symptoms to the body, but the bodies immune system will recognize this foreign particles antigens and this will stimulate the production of antigens that work against this particular strain of bacterial cells.
so the next time the same type of bacterial cell which is live, that enters the body, the body already has the template to create antibodies faster to kill off the cells.
so the answer is of courseeeeeeeeeeeee....?
B. They inject a small amount of the virus into the body so the white blood cells can get used to it so if a large amount of that virus neters it can digest it because it is not a foreign body.
The answer is D.
Do I get an A for doing your homework?
D. They stimulate the immune system to recognize and kill any virally infected cells the next time you're exposed to the disease.
