I have finals next week for school and I need help in two questions for Biology class. These are the questions: Why is it important for a person to finish all of his or her antibiotics? How does a vaccine work to prevent a person from developing an infection? PLEASE HELP!
* Responses that I don't like will be reported for abuse!

it's important to maintain a certain concentration level of the antibiotic in order to kill the bacteria if you stop the antibiotic it just won't be able to work the next time you need it cause the bacteria is resistant to it. and a vaccine is usually inactivated virus and when they get into your body your body developes antibodies and when you get an active virus the antibodies will fight it

The "finish all your antibiotics" answer requires you to believe that bacteria evolve. If you take enough antibiotics to kill nearly all of the bacteria in your system, the survivors are the ones that are resistant to the antibiotic. Then they multiply, and the antibiotic can't stop them. So you have to keep taking the antibiotic to allow your immune system finish off the resistant ones.
The vaccine question is more involved. Basically, a vaccine gives your immune system a taste of things to come so it can prepare to fight the real disease.

I'm really not sure about the antibiotic one. I know if you don't finish them it just makes the bacteria harder to get rid of.
But i do know the answer to the vaccine one. I just had my bio exam todat and that was on it. A vaccine actually contains the disabled pathogens, or the things that make you sick, of the virus you are trying to treat or a similar but less harmful version. when you are given the vaccine, the disabled pathogen stimulate your immune system to build up against that virus, that way when you do come in contact with it your body is ready to fight it so you don't get sick. Since the pathogens are disable, the vaccine won't make you sick.
I hope i answered that question.

If you don't finish all your antibiotics it doesn't completely kill off the infection..the infection can then lie dormant and and reappear when you immunity is down.
Vaccines usually gives you part of the bacteria that you are trying to prevent so your body naturally builds up antibodies against it.

Hi Diana, this is your teacher. Nice to see you are studying.
The first question you'll find the answer to in your textbook under "Bacterial Resistance".
The second question you'll find the answer to, also in your textbook, under the section on "Immune System Learning".
Good luck. I'll be sure to make these questions extra-challenging for you.
